发明详述
在本发明中，除非另有说明，否则本文中使用的科学和技术名词具有本领域技术人员所通常理解的含义。并且，本文中所用的蛋白质和核酸化学、分子生物学、细胞和组织培养、微生物学、免疫学相关术语和实验室操作步骤均为相应领域内广泛使用的术语和常规步骤。例如，本发明中使用的标准重组DNA和分子克隆技术为本领域技术人员熟知，并且在如下文献中有更全面的描述：Sambrook，J.，Fritsch，E.F.和Maniatis，T.，MolecularCloning：A Laboratory Manual；Cold Spring Harbor Laboratory Press：Cold SpringHarbor，1989(下文称为“Sambrook”)。同时，为了更好地理解本发明，下面提供相关术语的定义和解释。
在第一方面，本发明提供一种检测生物样品中靶核酸分子的存在和/或量的方法，所述方法包括以下步骤：
(a)使所述生物样品接触：i)Cas12b蛋白，ii)针对所述靶核酸分子中的靶序列的gRNA，和iii)被切割后产生可检测信号的单链DNA报告分子，从而形成反应混合物；
(b)检测所述反应混合物中产生的可检测信号的存在和/或水平，
其中所述可检测信号的存在和/或水平代表所述靶核酸分子的存在和/或量。
在一些实施方案中，所述靶核酸分子是双链DNA分子。在一些实施方案中，所述靶核酸分子是单链DNA分子。所述靶核酸分子可以是基因组DNA、cDNA、病毒DNA等，或它们的片段。
“Cas12b”、“Cas12b核酸酶”、“Cas12b蛋白”、“C2c1”、“C2c1核酸酶”和“C2c1蛋白”在本文中可互换使用，指的是一种来自微生物CRISPR系统的RNA指导的序列特异性核酸酶。Cas12b能在向导RNA的指导下靶向并切割DNA靶序列形成DNA双链断裂(DSB)，也称作经典dsDNA切割活性。更重要的是，Cas12b与gRNA的复合物在识别并结合相应靶DNA序列后，能够激活其非特异性单链DNA切割活性，也称作非经典旁路ssDNA切割活性。利用非经典旁路ssDNA切割活性，切割在被切割后产生可检测信号的单链DNA报告分子，即可以反映靶DNA的存在和/或量。在本文中，被Cas12b与gRNA的复合物识别并结合，激活Cas12b的非特异性单链DNA切割活性的DNA分子也称作“激活物”。
在一些实施方案中，所述Cas12b蛋白是来自Alicyclobacillus acidiphilus的AaCas12b蛋白、来自Alicyclobacillus kakegawensis的AkCas12b蛋白、来自Alicyclobacillus macrosporangiidus的AmCas12b蛋白、来自Bacillus hisashii的BhCas12b蛋白、来自Bacillus属的BsCas12b蛋白、来自Bacillus属的Bs3Cas12b蛋白、来自Desulfovibrio inopinatus的DiCas12b蛋白、来自Laceyella sediminis的LsCas12b蛋白、来自Spirochaetes bacterium的SbCas12b蛋白、来自Tuberibacillus calidus的TcCas12b蛋白。在一些优选实施方案中，所述Cas12b蛋白是来自Alicyclobacillus acidiphilus的Cas12b蛋白(AaCas12b)。本申请人已经鉴定这些Cas12b蛋白可以用于在哺乳动物中进行基因组编辑，也可以用于本发明的核酸检测方法。
例如，所述Cas12b蛋白是来自Alicyclobacillus acidiphilus NBRC 100859的AaCas12b蛋白、来自Alicyclobacillus kakegawensis NBRC 103104的AkCas12b蛋白、来自Alicyclobacillus macrosporangiidus strain DSM 17980的AmCas12b蛋白、来自Bacillus hisashii strain C4的BhCas12b蛋白、来自Bacillus属NSP2.1的BsCas12b蛋白、来自Bacillus属V3-13contig_40的Bs3Cas12b蛋白、来自Desulfovibrio inopinatus DSM10711的DiCas12b蛋白、来自Laceyella sediminis strain RHA1的LsCas12b蛋白、来自Spirochaetes bacterium GWB1_27_13的SbCas12b蛋白、来自Tuberibacillus calidusDSM 17572的TcCas12b蛋白。在一些优选实施方案中，所述Cas12b蛋白是来自Alicyclobacillus acidiphilus NBRC 100859的Cas12b蛋白。
Alicyclobacillus acidiphilus的Cas12b的基因座上缺少已经测序的直接重复(DR)阵列，因此本领域技术人员将会认为其无法进行基因编辑，从而在CRISPR核酸酶筛选中将其略过。然而，本发明人令人惊奇地发现，来自Alicyclobacillus acidiphilus的Cas12b蛋白同样具有经典靶向dsDNA切割活性和非经典旁路ssDNA切割活性，从而能用于基因编辑和核酸检测。类似地，所鉴定的其它一些Cas12b蛋白，例如DiCas12b或TcCas12b蛋白，尽管其天然基因座不具有CRISPR阵列，也出乎意料地可以用于本发明。
在本发明一些实施方式中，所述Cas12b蛋白是其天然基因座不具有CRISPR阵列的Cas12b蛋白。在一些实施方式中，所述天然基因座不具有CRISPR阵列的Cas12b蛋白是AaCas12b蛋白、DiCas12b或TcCas12b蛋白。
在一些实施方案中，所述Cas12b蛋白包含与SEQ ID NO:1-10中任一个具有至少80％、至少85％、至少90％、至少95％、至少96％、至少97％、至少98％、至少99％序列相同性的氨基酸序列。在一些实施方案中，所述Cas12b蛋白的氨基酸序列相对于SEQ ID NO:1-10中任一个具有一或多个氨基酸残基取代、缺失或添加。例如，所述Cas12b蛋白相对于SEQ IDNO:1-10中任一个具有1个、2个、3个、4个、5个、6个、7个、8个、9个或10个氨基酸残基取代、缺失或添加的氨基酸序列。在一些实施方案中，所述氨基酸取代是保守型取代。在一些实施方案中，所述Cas12b蛋白包含SEQ ID NO:1-10中任一所示的氨基酸序列。例如，所述AaCas12b、AkCas12b、AmCas12b、BhCas12b、BsCas12b、Bs3Cas12b、DiCas12b、LsCas12b、SbCas12b、TcCas12b蛋白分别包含SEQ ID NO:1-10所示氨基酸序列。在一些优选实施方式中，所述Cas12b蛋白包含SEQ ID NO:1所示的氨基酸序列。
本发明人已经证明了Cas12b蛋白的RuvC结构域对于其非经典旁路ssDNA切割活性是关键的。在一些实施方案中，所述Cas12b蛋白包含野生型Cas12b蛋白的RuvC结构域，所述野生型Cas12b蛋白例如包含SEQ ID NO:1-10任一项所示氨基酸序列。本领域技术人员可以容易地鉴定出Cas12b蛋白的RuvC结构域。例如，通过NCBI提供的工具。
序列“相同性”具有本领域公认的含义，并且可以利用公开的技术计算两个核酸或多肽分子或区域之间序列相同性的百分比。可以沿着多核苷酸或多肽的全长或者沿着该分子的区域测量序列相同性。(参见，例如：Computational Molecular Biology,Lesk,A.M.,ed.,Oxford University Press,New York,1988；Biocomputing:Informatics and GenomeProjects,Smith,D.W.,ed.,Academic Press,New York,1993；Computer Analysis ofSequence Data,Part I,Griffin,A.M.,and Griffin,H.G.,eds.,Humana Press,NewJersey,1994；Sequence Analysis in Molecular Biology,von Heinje,G.,AcademicPress,1987；and Sequence Analysis Primer,Gribskov,M.and Devereux,J.,eds.,MStockton Press,New York,1991)。虽然存在许多测量两个多核苷酸或多肽之间的相同性的方法，但是术语“相同性”是技术人员公知的(Carrillo,H.&Lipman,D.,SIAM J AppliedMath 48:1073(1988))。
在肽或蛋白中，合适的保守型氨基酸取代是本领域技术人员已知的，并且一般可以进行而不改变所得分子的生物活性。通常，本领域技术人员认识到多肽的非必需区中的单个氨基酸取代基本上不改变生物活性(参见，例如，Watson et al.,Molecular Biologyof the Gene,4th Edition,1987,The Benjamin/Cummings Pub.co.,p.224)。
特别地，本领域人员将可以理解，在同一细菌物种的不同菌株Cas12b蛋白可能在氨基酸序列存在一定差异，但是却能实现基本上相同的功能。
在一些实施方案中，所述Cas12b蛋白是重组产生的。在一些实施方案中，所述Cas12b蛋白还含有融合标签，例如用于Cas12b蛋白分离/和或纯化的标签。重组产生蛋白质的方法是本领域已知的。并且本领域已知多种可以用于分离/和或纯化蛋白质的标签，包括但不限于His标签、GST标签等。通常而言，这些标签不会改变目的蛋白的活性。
向导RNA”和“gRNA”在本文中可互换使用，通常由部分互补形成复合物的crRNA和tracrRNA分子构成，其中crRNA包含与靶序列具有足够相同性以便与靶序列的互补序列杂交并且指导CRISPR复合物(CRISPR核酸酶+crRNA+tracrRNA)与该靶序列以序列特异性方式结合的序列。然而，可以设计并使用单向导RNA(sgRNA)，其同时包含crRNA和tracrRNA的特征。不同的CRISPR核酸酶对应的gRNA存在不同。例如，Cas9和Cas12b通常需要crRNA和tracrRNA两者，然而，Cas12a(Cpf1)则只需要crRNA。
“针对靶核酸分子的靶序列的gRNA”指的是gRNA能够特异性识别所述靶序列。例如，在一些实施方案中(靶核酸分子是双链DNA)，所述gRNA包含能够与靶序列的互补序列特异性杂交的间隔区序列(spacer)。在一些实施方案中(靶核酸分子是单链DNA)，所述gRNA包含能够与靶序列特异性杂交的间隔区序列。
A.acidiphilus CRISPR基因座中没有直接重复序列(DR)阵列，因此，AaCas12b并没有对应的crRNA。然而，本发明人发现，AaCas12b也可以采用来自其他生物体的Cas12b蛋白的相应gRNA。例如AaCas12b可以采用自身的tracrRNA和来自A.acidoterrestris的CRISPR基因座的crRNA序列作为gRNA。本发明人对可用于AaCas12b的gRNA进行了优化。
在本发明的一些实施方案中，所述向导RNA是由crRNA和tracrRNA部分互补形成的复合物。在一些实施方案中，所述tracrRNA由以下的核酸序列编码：5’-GTCTAAAGGACAGAATTTTTCAACGGGTGTGCCAATGGCCACTTTCCAGGTGGCAAAGCCCGTTGAACTTCTCAAAAAGAACGCTCGCTCAGTGTTCTGAC-3’。在一些实施方案中，所述crRNA由以下的核酸序列编码：5’-GTCGGATCACTGAGCGAGCGATCTGAGAAGTGGCAC-Nx-3’，其中Nx表示X个连续的核苷酸组成的核苷酸序列，N各自独立地选自A、G、C和T；X为18≤X≤35的整数。优选地，X＝20。在一些实施方案中，Nx是能够与靶序列的互补序列特异性杂交的间隔区序列(靶核酸分子是双链DNA)。在一些实施方案中，Nx是能够与靶序列特异性杂交的间隔区序列(靶核酸分子是单链DNA)。
在本发明的一些实施方案中，所述向导RNA是sgRNA。在一些实施方案中，所述sgRNA由5’端的支架序列和3’端的间隔区序列组成。间隔区序列可以与靶序列或靶序列的互补序列特异性杂交。间隔区序列通常长度为18至35个核苷酸，优选20个核苷酸。

其中Nx表示X个连续的核苷酸组成的核苷酸序列(spacer序列)，N各自独立地选自A、G、C和T；X为18≤X≤35的整数。优选地，X＝20。在一些实施方案中，序列Nx(spacer序列)能够与靶序列的互补序列特异性杂交。所述sgRNA中除Nx之外的序列为sgRNA的支架(scaffold)序列。
在一些实施方案中，所述人工sgRNA包含由SEQ ID NO:30-66中任一项的核苷酸序列编码的支架序列。
在一些实施方案中，所述gRNA的间隔区序列被设计为与靶序列或其互补序列完全匹配。在一些实施方案中，所述gRNA的间隔区序列被设计为与靶序列或其互补序列具有至少一个核苷酸错配，例如具有一个核苷酸错配。这样的gRNA也称为经调节的(tuned)gRNA，所述核苷酸错配也成为调节位点。利用Cas12b对sgRNA与靶之间不同错配的耐受能力差异，设计为与靶序列或其互补序列具有核苷酸错配的gRNA能够区分靶序列中的单核苷酸多态性变异。在一些实施方案中，所述至少一个核苷酸错配的位置不同于所述单核苷酸多态性变异的位置。例如，经调节的sgRNA与靶序列1在位置1具有一个核苷酸错配，而靶序列1与靶序列2在位置2具有单核苷酸多肽性，也即经调节的sgRNA与靶序列2之间具有两个核苷酸错配。由于Cas12b对错配数目的耐受性差异，其仅在靶序列1存在时产生可检测信号(只有1个错配)，而靶序列2没有可检测信号(由于存在两个错配)，从而可以将包含单核苷酸多态性的靶序列1和靶序列2区分开。本领域技术人员可以根据具体的靶序列筛选合适的调节位点。
本发明中，gRNA中除间隔区序列之外的序列也称做gRNA支架(scaffold)。
在一些实施方案中，所述gRNA体外转录产生。在一些实施方案中，所述gRNA通过化学合成产生。
在本发明的一些实施方案中，所述靶核酸分子包含特征性的长度为18-35个核苷酸，优选20个核苷酸的靶序列。在本发明的一些实施方案中，特别是涉及双链DNA检测，所述靶序列在紧接其5’端具有选自：5’TTTN-3’、5’ATTN-3’、5’GTTN-3’、5’CTTN-3’、5’TTC-3’、5’TTG-3’、5’TTA-3’、5’TTT-3’、5’TAN-3’、5’TGN-3’、5’TCN-3’和5’ATC-3’的PAM(前间区邻近基序)序列，优选5’TTTN-3’。
“被切割后产生可检测信号的单链DNA报告分子”例如可以在单链DNA的两端分别包含荧光团和其猝灭基团。当单链DNA未被切割时，由于猝灭基团存在，荧光团不发出荧光。而当Cas12b-gRNA复合物被靶核酸分子激活，通过其非经典旁路ssDNA切割活性切割所述单链DNA报告分子的DNA单链时，荧光团被释放，从而发出荧光。合适的荧光团及其相应猝灭基团，以及其标记核酸分子的方法在本领域是已知的。合适的荧光团包括但不限于FAM、TEX、HEX、Cy3或Cy5。合适的猝灭基团包括但不限于BHQ1、BHQ2、BHQ3或TAMRA。合适的荧光团-猝灭基团对包括但不限于FAM-BHQ1、TEX-BHQ2、Cy5-BHQ3、Cy3-BHQ1或FAM-TAMRA。因此，在一些实施方案中，所述可检测信号是荧光信号。在一些实施方式中，所述荧光团是FAM，所述猝灭基团是BHQ1。
所述单链DNA报告分子中单链DNA的长度可以是大约2-100个核苷酸，例如2-5个、2-10个、2-15个、2-20个、2-25个、2-30个、2-40个或2至更多个核苷酸。所述单链DNA报告分子中单链DNA可以包含任意序列，但在一些实施方案中，polyG(聚鸟苷酸)除外。在一些实施方案中，所述单链DNA报告分子中的单链DNA可以选自polyA(聚腺苷酸)、polyC(聚胞苷酸)或polyT(聚胸苷酸)。
在一些具体实施方式中，所述单链DNA报告分子选自5’-FAM-AAAAA-BHQ1-3’、5’-FAM-TTTTT-BHQ1-3’、和5’-FAM-CCCCC-BHQ1-3’。
在本发明的方法的一些实施方案中，还包括在步骤(a)之前对所述生物样品中的核酸分子进行扩增的步骤。所述扩增包括但不限于PCR扩增或重组酶聚合酶扩增(Recombinase Polymerase Amplification，RPA)。优选地，所述扩增是重组酶聚合酶扩增。
在一些实施方案中，所述重组酶聚合酶扩增进行约10分钟-约60分钟
在一些实施方案中，在与所述生物样品接触之前，所述Cas12b蛋白已经与所述gRNA预先复合形成Cas12b-gRNA复合物。

在一些实施方案中，步骤(a)在合适的缓冲液中进行。例如，所述缓冲液是NEBufferTM2、NEBufferTM2.1或Buffer。在一些实施方式中，所述缓冲液包含终浓度50mM NaCl、10mM Tris-HCl、10mM MgCl2、1mM DTT，pH7.9。在一些实施方式中，所述缓冲液包含终浓度50mM NaCl、10mM Tris-HCl、10mM MgCl2、100μg/ml BSA，pH7.9。在一些实施方式中，所述缓冲液包含终浓度50mM乙酸钾,20mM Tris-乙酸,10mM乙酸镁,100μg/ml BSA,pH 7.9。
可用于本发明的方法的生物样品包括但不限于全血、血浆、血清、脑脊液、尿液、粪便、细胞或组织提取物等。所述生物样品涵盖提取自细胞或组织的核酸样品。
本发明的范围内还包括用于本发明的方法的试剂盒，该试剂盒包括用于实施本发明的方法的试剂，以及使用说明。例如，所述试剂盒可以包括Cas12b蛋白(例如本发明的Cas12b蛋白)、gRNA(例如包含本发明的gRNA支架)或用于产生gRNA(例如其包含本发明的gRNA支架)的试剂、单链DNA报告分子(例如本发明的单链DNA报告分子)，合适的缓冲液、和/或核酸扩增试剂。试剂盒一般包括表明试剂盒内容物的预期用途和/或使用方法的标签。术语标签包括在试剂盒上或与试剂盒一起提供的或以其他方式随试剂盒提供的任何书面的或记录的材料。
本发明还提供了上文所定义的Cas12b蛋白和/或包含本发明的支架的gRNA和/或用于产生包含本发明的支架的gRNA的试剂在制备用于本发明的方法的试剂盒中的用途。
实施例
实验材料和方法
蛋白表达和纯化
SpCas9和LbCas12a蛋白商购获得(NEB)。根据之前的报道纯化AaCas12b、ArCas12a、HkCas12a和PrCas12a蛋白。简言之，BPK2014-Cas12-His10蛋白在大肠杆菌菌株BL21(λDE3)中表达，用0.5mM IPTG在16℃诱导表达16小时。收获细胞沉淀并裂解，使用His60Ni Superflow Resin(Takara)纯化。将纯化的Cas12蛋白透析，浓缩，最后使用BCA蛋白质测定试剂盒(Thermo Fisher)定量。
核酸制备
DNA寡核苷酸商购获得(Genscript)。双链DNA激活物通过PCR扩增获得并使用Oligo Clean&Concentrator Kit(ZYMO Research)纯化。向导RNA使用HiScribeTMT7 HighYield RNA Synthesis Kit(NEB)体外转录并用MicroElute RNA Clean Up Kit(Omega)纯化。
在指定反应中使用的背景基因组DNA使用Mouse Direct PCR Kit(Bimake)纯化自人胚肾293T细胞。为了模拟无细胞DNA(cfDNA)，dsDNA以指定浓度稀释至人血浆中(ThermoFisher)。
荧光团猝灭剂(FQ)-标记的报告测定
用30nM Cas12、36nM gRNA、混合在40ng背景基因组DNA中(在指定的反应中)的40nM激活物(除非另有说明)、200nM定制合成的均聚物ssDNA FQ报告基因(表1)和NEBufferTM2(除非另有说明)在Corning 384-孔聚苯乙烯NBS微孔板中进行20μl反应检测测定。将反应物在37℃下孵育以在荧光板读数器(BioTek Synergy 4)中指示时间，每5分钟测量荧光动力学(λex＝485nm；λem＝528nm，透射增益＝61)。通过SigmaPlot软件分析荧光结果。
重组酶聚合酶扩增(RPA)反应
根据制造商的方案，使用TwistAmp Basic(TwistDx)进行重组酶聚合酶扩增(RPA)反应。将含有不同DNA输入量的50μl RPA反应系统在37℃下孵育10分钟。如上所述，将16μlRPA产物直接转移至20μl检测试验。
实施例1、Cas12b的反式ssDNA切割活性的表征
源自Alicyclobacillus acidiphilus NBRC 100859的CRISPR-Cas12b核酸酶(AaCas12b，氨基酸序列示于SEQ ID NO:1)已被用于哺乳动物基因组编辑，因为其具有经典的dsDNA靶向切割能力(图1a)。为了表征Cas12b的非经典反式旁路切割活性，使用Cas12b、Cas12a和Cas9分别与其相应的向导RNA(gRNA)组合进行体外ssDNA切割测定。结果表明，AaCas12b和Cas12a(ArCas12a、HkCas12a和PrCas12a)在靶向M13的sgRNA(OT-gRNA)存在下可诱导单链M13DNA噬菌体快速降解，而SpCas9则不能(图1b)。同样，AaCas12b和Cas12a在存在与M13噬菌体基因组没有序列同源性的非靶gRNA及其互补ssDNA“激活物”的情况下也实现了M13降解(图1c)。催化失活的变体(发生R785A和D977A取代)中非经典旁路ssDNA切割活性被消除，表明该旁路切割活性是RuvC结构域依赖性的(图2)。这些结果表明AaCas12b-sgRNA复合物一旦被与向导序列互补的DNA触发，就可以获得非特异性ssDNA反式切割活性。
实施例2、开发Cas12b介导的DNA检测系统
为了开发Cas12b介导的DNA检测系统，首先分析了AaCas12b-sgRNA复合物对荧光团-猝灭剂(FQ)标记的同聚物报告分子的切割偏好。发现AaCas12b偏好多聚胸苷酸(ployT)以及多聚腺苷酸(poly A)和多聚胞苷酸(poly C)，而多聚鸟苷酸(poly G)基本上不被切割(图3a)。同时，可以优化切割效率，其在NEBufferTM 2表现最佳(图3b)。然后，使用NEBufferTM2中的poly T报告分子进行AaCas12b介导的切割测定。使用sgRNA-互补的OT-ssDNA和OT-dsDNA(OT表示on target，在靶)，或sgRNA-非互补的NT-ssDNA和NT-dsDNA(NT表述non target，非靶)作为激活物，发现了OT-ssDNA和OT-dsDNA激活物能够触发AaCas12b切割FQ-报告分子，尽管OT-dsDNA效率较低(图3c)。
接下来使用带有不同错配的ssDNA或dsDNA激活物测试了反式切割活化的特异性。发现PAM序列对于dsDNA激活物触发的AaCas12b的反式切割活性至关重要，并且对于ssDNA不是必须的(图4a、b)。同时，还发现dsDNA激活物和sgRNA之间的错配会阻碍甚至消除反式切割活性，而ssDNA激活物则对错配更耐受(图4a、b)。
然后确定了AaCas12b-sgRNA-激活物系统的灵敏度，发现没有预扩增，AaCas12b在ssDNA-激活物输入浓度<1.6nM或dsDNA-激活物输入浓度<8nM时不产生可检测信号(图5a)。
由于dsDNA激活物具有更高的特异性(图4a、b)，将AaCas12b-sgRNA-dsDNA激活系统设计为DNA检测平台(Cas12b-based DNA detection，CDetection)。合成了一种花椰菜花叶病毒(CaMV)的dsDNA和两种人乳头瘤病毒(HPV16和HPV18)的dsDNA作为在检测反应中的激活物。当激活物的输入浓度≥10nM时，AaCas12b-sgRNA不仅可以产生可检测的信号(图5b，c)，还可以区分两种dsDNA病毒HPV16和HPV18(图5c)。
与基于Cas12a的DNA检测相比，AaCas12b在这两个检测位点均展示更高的检测灵敏度，因此CDetection产生更高的信号水平和更低的背景水平(图4c和图5d)。
为了提高灵敏度，使用重组酶聚合酶扩增(RPA)进行了预扩增，并在实现单分子检测(图4d和图5e)。这些结果表明，Cas12b介导的DNA检测(CDetection)可以实现具有高特异性和渺摩尔级灵敏度的DNA检测，其灵敏度高于基于Cas12a的检测平台(图4e)。
实施例3、开发增强型Cas12b介导的DNA检测系统
为了扩展和模拟CDetection在分子诊断应用中的应用，将合成的HPV dsDNA稀释到人类基因组DNA中。结果显示CDetection可以在亚渺摩尔级下检测出感染性病毒靶标(图6a)。
AaCas12b在人血浆中的高灵敏度促使测试CDetection在基于cfDNA的非侵入性诊断中的应用。虽然之前使用过cfDNA分析灵敏度达到了108分之一，但这些方法需要相对大量的cfDNA(5-10ng/ml血浆)，并且是耗时的。为了证明CDetection在cfDNA检测中的优势，将HPV的dsDNA稀释进人血浆中并检测该新方法的灵敏度。结果显示，CDetection可以检测人血浆中浓度低至的HPV DNA的存在(图4f和图6b)，表明可以用仅仅一滴血快速检测存在的感染性病毒。
为了扩展CDetection在精确诊断中的应用，我们设计了使用三种靶向sgRNA和相应的dsDNA激活物(on-以及off-激活物)的实验来鉴定六种常见的人ABO等位基因。理论上，携带三种sgRNA中的每一种的CDetection可分别鉴定出O01、O02/O03和B101。如果所有sgRNA的荧光信号没有检测到，则等位基因应为A101/A201(图7a)。结果显示，CDetection无法区分不同的ABO等位基因，因为它产生在on和off的dsDNA激活物组之间难以区分的荧光信号(图7b)。
为了增强CDetection的特异性，设计了在间隔区序列(spacer)中含有单核苷酸错配的经调节的向导RNA(tuned gRNA，tgRNA)，其使得只有单个核苷酸差异的两种相似靶标由不可区分变为可区分(图7c)。
为了证明这种增强的CDetection(eCDetection)的单碱基分辨率灵敏度，进行了ABO血液基因分型测试。结果表明，eCDetection可以高精度地确定血型，而CDetection则不能(图8a)。
测序和探针检测是检测点突变引起的疾病的两种主要方法。然而，测序是昂贵且耗时的，并且其灵敏度取决于测序深度。基于探针的方法对单碱基突变的敏感性较差。由于本发明的eCDetection方法具有高特异性和灵敏度，可以使用eCDetection检测人类基因组中的低比率单碱基突变。
选择了癌症相关的TP53 856G>A突变来测试其可行性。结果表明，CDetection可以使用选定的tgRNA准确区分点突变等位基因与野生型等位基因(图9a)。
此外，应用CDetection平台检测乳腺癌相关BRCA1基因的两个热点(3232A>G和3537A>G)。用选择的tgRNA(tgRNA-3232-1和tgRNA-3537-4)进行CDetection可以很好地区分点突变，而sgRNA几乎不支持点突变检测(图8b、c和图9b、c)。
此外，为了模拟通过CDetection使用cfDNA早期临床检测原发疾病，将BRCA13232A>G dsDNA稀释到人血浆中。研究结果表明，CDetection可以在单碱基分辨率下实现点突变检测(图8d和图9d)。本发明的eCDetection能够以单碱基分辨率在临床研究实现快速DNA检测。
总之，本发明提供了CDetection平台，该平台基于Cas12b核酸酶的非经典旁路ssDNA切割特性，可以渺摩尔级灵敏度检测DNA。同时，结合经调节的gRNA，开发了增强版(eCDetection)，实现单核苷酸分辨率。本发明的CDetection和eCDetection平台可以在各种分子诊断应用中更容易地检测核酸，以及在临床研究中进行基因型分析(图10)。
实施例4、其他Cas12b蛋白的鉴定
选择并从头合成来自不同细菌的六种代表性Cas12b蛋白，以及之前报道的四种Cas12b直系同源物，在人胚胎肾293T细胞中进行基因组编辑(图11、12和SEQ ID NO:1-10)。在这10种Cas12b直系同源物中，来自D.inopinatus(DiCas12b)和T.calidus(TcCas12b)的Cas12b既没有可预测的前体CRISPR RNA(pre-crRNA)也没有反式激活crRNA(tracrRNA)(图11b)，提示这两种Cas12b蛋白可能不适合基因组编辑应用。
为了进行哺乳动物基因组编辑，用单独的Cas12b酶和其靶向含有适当PAM的人内源基因座的同源单向导RNA(sgRNA)共转染293T细胞(图11)。T7核酸内切酶(T7EI)测定的结果显示，AaCas12b、AkCas12b、AmCas12b、BhCas12b、Bs3Cas12b和LsCas12b稳健地编辑人类基因组，尽管它们的靶向效率在不同的直系同源物之间和在不同的靶向位点不同(图11b和图13a)。还通过简单地使用多个sgRNA，使用Bs3Cas12b实现多重基因组编辑，同时编辑人类基因组中的四个位点(图13b，c)。这些新发现的有功能的Cas12b直系同源物扩展对基于Cas12b的基因组编辑的选择，同时扩展了基于Cas12b的DNA检测的选择。
实施例5、不同Cas12b及双RNA的可互换性
为了研究Cas12b系统中双RNA(crRNA和tracRRNA)和蛋白质组分之间的可互换性，首先分析Cas12b蛋白和双RNA两者的保守性。除了Cas12b直系同源物的保守氨基酸序列外(图14a和图12)，前体crRNA:tracrRNA双链体的DNA序列及其二级结构也表现出高保守性(图11b和图15)。接下来，用分别与来自8个Cas12b系统的各sgRNA复合的8种Cas12b直系同源物，在293T细胞中进行基因组编辑。如T7EI测定的结果所示，衍生自AaCas12b、AkCas12b、AmCas12b、Bs3Cas12b和LsCas12b基因座的sgRNA可以替代原始sgRNA用于哺乳动物基因组编辑，尽管在不同Cas12b直系同源物和sgRNA之间的活性有所不同(图14c，d和图16)。这些结果证明不同Cas12b和来自不同Cas12b基因座的双RNA之间的可互换性。
实施例6、利用天然基因座无CRISPR阵列的Cas12b进行基因组编辑
本发明进一步选择两个基因座没有携带CRISPR阵列的Cas12b直系同源物DiCas12b和TcCas12b进行后续实验(图17a)。基因座没有携带CRISPR阵列使得它们的crRNA:tracrRNA双链体的序列不可预测。在293T细胞中共转染与靶向不同基因组位点的衍生自其他8种Cas12b直系同源物的基因座的sgRNA组合的DiCas12b和TcCas12b以及AaCas12b。T7EI测定结果表明衍生自AaCas12b、AkCas12b、AmCas12b、Bs3Cas12b和LsCas12b的sgRNA使TcCas12b能够稳健地编辑人类基因组(图17b、c和图18)。此外，AasgRNA或AksgRNA能够使TcCas12b实现多重基因组编辑(图17d和图19)。上述结果表明在来自不同系统的Cas12b和双链RNA之间可互换性使得可能利用天然基因座不具有CRISPR阵列的Cas12b直系同源物来编辑哺乳动物基因组。
实施例7、设计用于Cas12b介导的基因组编辑的人工sgRNA
不同Cas12b系统中Cas12b蛋白和双RNA之间的可互换性有利于设计新的人工sgRNA(artsgRNA)支架以促进Cas12b介导的基因组编辑。考虑到Cas12b直系同源物中DNA序列和二级结构的保守性(图11b和13)，设计并从头合成37种sgRNA支架(SEQ ID NO:30-66)，用于靶向人CCR5基因座(图17e，图20a)。T7EI测定的结果表明22种artsgRNA支架有效地工作(图10b)。为了验证artgRNA的普遍适用性，使用artsgRNA13指导TcCas12b或AaCas12b进行多重基因组编辑(图20a)。T7EI测定结果表明，artsgRNA13同时促进TcCas12b和AaCas12b两者的多重基因组编辑(图17f和图20c)。结果表明通过设计和合成artsgRNA能促进Cas12b介导的基因组编辑特别是多重基因组编辑。
