Description
技术领域
本发明涉及基于自组装铁蛋白纳米抗原颗粒,尤其涉及包含由流感病毒血凝素蛋白和单体铁蛋白亚基融合在一起的纳米抗原颗粒以及由该纳米颗粒抗原制备的流感疫苗,属于流感疫苗领域。
背景技术
流行性感冒(简称流感)是由流感病毒(influenza virus)引起的一种急性呼吸道传染病,流感病毒具有传染性强,发病率高,波及面广等特点,对人类健康和全球经济造成了严重影响。流感病毒分为甲(A)、乙(B)、丙(C)三型,近年来才发现的牛流感病毒将归为丁(D)型。其中,甲型流感病毒经常发生抗原变异,在全球引发了数次流感大流行。防治流感病毒最好的工具主要是疫苗,目前使用的流感疫苗主要机理是诱导机体产生针对流感病毒表面抗原血凝素(hemagglutin,HA)和神经氨酸酶(neuraminidase,NA)的保护性抗体,但是甲型流感病毒表面容易发生抗原漂移和抗原转换,这就需要定期重新设计疫苗来适应来年最可能引发流感的病毒。针对目前流感病毒防治趋势,制备出一种具有广谱,高效免疫效力的通用疫苗迫在眉睫。针对疾病最好的治疗方案莫过于防患未然,而针对各种疾病的疫苗正式发挥预防作用的主力军。传统的疫苗多为减毒活疫苗,包括天然减毒株和基因重组弱毒株等。应用减毒株疫苗的最大缺陷是减毒株在易感群体中有恢复毒力作用的风险。因此,生产安全、高效及廉价的基因工程疫苗成为新的需求。而由24个亚基自组装而成的铁蛋白纳米粒子正式一个理想的抗原呈递和疫苗开发平台。
近年来,铁蛋白(Ferritin)作为一种纳米材料在多个领域得到应用。铁蛋白是一种广泛存在于生物体中的笼状蛋白,其蛋白外壳由24个铁蛋白亚基自组装而成,其中每三个亚基组成一个三聚体亚单位。铁蛋白的N末端伸向外表面,易于进行基因修饰,融合蛋白多肽。高度有序重复抗原在微生物体表面以5-10nm间隔分布时易于诱导产生强烈的T细胞依赖的抗体反应。铁蛋白非常稳定,能够耐受高温(70-80℃)和多种变性剂而不影响天然蛋白结构。铁蛋白对pH敏感,在pH2.0的酸性条件下蛋白壳发生解体,而当pH恢复到生理条件(pH 7.0)时,解体的蛋白亚基又能重新组装成完整的铁蛋白。近年来对铁蛋白的研究主要集中在:(1)通过对铁蛋白内表面的修饰使铁蛋白壳内包裹上特定药物或者促进纳米材料的合成;(2)通过对铁蛋白外表面的修饰与PEG或抗体连接以扩展新的功能;(3)通过铁蛋白外表面或亚基间接触面的修饰控制铁蛋白的自组装。铁蛋白纳米颗粒展示抗原,能够显著地增强抗原的免疫原性,引起更强的体液、细胞免疫反应,因此铁蛋白是理想的纳米疫苗平台。
发明内容
本发明的目的之一是提供一种包含融合蛋白的自组装铁蛋白纳米抗原颗粒;
本发明的目的之二是将所述融合蛋白进行突变进而提高融合蛋白的表达量或表达效率;
本发明的目的之三是提供基于自组装铁蛋白纳米抗原颗粒得到的纳米颗粒流感疫苗;
本发明目的之四提供高效表达所述融合蛋白的方法;
本发明目的之五是提供一种将自组装铁蛋白纳米颗粒与血凝素蛋白所构建的融合基因呈递给动物体内并在动物体内呈递抗原诱导产生抗体的方法。
为了实现上述目的,本发明所采取的技术方案是:
本发明首先提供了一种包含融合蛋白的纳米抗原颗粒,所述融合蛋白由流感病毒血凝素蛋白和单体铁蛋白亚基的N端连接得到;
所述单体铁蛋白亚基包括细菌铁蛋白、植物铁蛋白、藻铁蛋白、昆虫铁蛋白、真菌铁蛋白或哺乳动物铁蛋白中的任何一种;优选的,所述单体铁蛋白亚基是幽门螺杆菌铁蛋白单体,其氨基酸序列为SEQ ID NO.1所示,其编码基因的核苷酸序列为SEQ ID NO.2所示;、。
所述流感病毒血凝素蛋白是H9流感病毒血凝素蛋白或H5流感病毒血凝素蛋白;优选的,所述流感病毒血凝素蛋白所选区域包含选自以下区域:能够容许血凝素三聚体形成的区域、茎区、胞外结构域;最优选的,所述H9流感病毒血凝素蛋白只选取H9流感病毒血凝素蛋白的胞外结构域这一特定的部位,所述H5流感病毒血凝素蛋白只选取H5流感病毒血凝素蛋白的胞外结构域这一特定部位。
所述的H9流感病毒血凝素蛋白的氨基酸序列为SEQ ID NO.3所示;所述H5流感病毒血凝素蛋白的氨基酸序列为SEQ ID NO.5所示;
优选的,将流感病毒血凝素蛋白和单体铁蛋白亚基的N端通过连接肽SGG连接得到融合蛋白。
本发明所提供的一种融合蛋白的氨基酸序列为SEQ ID NO.7所示(H9 HA-Ferritin),其编码基因的核苷酸序列为SEQ ID NO.8所示;本发明所提供的另一种融合蛋白的氨基酸序列为SEQ ID NO.9所示(H5 HA-Ferritin),其编码基因的核苷酸序列为SEQID NO.10所示。
本发明为了提高流感病毒血凝素蛋白与铁蛋白单体连接后得到的融合蛋白的表达量,本发明进一步将SEQ ID NO.7以及SEQ ID NO.9所示的融合蛋白的同感序列进行突变优化,并在序列优化之后进行糖基化位点分析,以消除糖基化位点来增加可溶性表达。从而在同感序列优化之后进行氨基酸单位点突变,双位点突变和多位点突变,以提高其可溶性表达量和表达效率:
具体的,本发明人通过分析了20条最近年份,流行于不同地区的H5、H9毒株的血凝素蛋白氨基酸序列进行比对分析,找出一条最为通用的同感序列,作为相应毒株的抗原基因,以期取得最佳的保护效果;在此基础上,本发明进一步利用OptimumGeneTM技术对H5、H9血凝素蛋白氨基酸序列进行优化,将优化后的血凝素蛋白氨基酸序列和铁蛋白单体亚基氨基酸序列根据大肠杆菌密码子偏好性对氨基酸序列进行改造,对影响基因转录效率、翻译效率和蛋白折叠的GC含量、CpG二核苷酸含量、密码子偏好性、mRNA的二级结构、mRNA自由能稳定性、RNA不稳定性基因序列、重复序列等多种相关参数进行优化设计,并保持最终翻译成的蛋白序列不变。此外,为了提高铁蛋白的表达量,同时提高可溶表达,对铁蛋白单体亚基进行点突变N19Q。最终,本发明将SEQ ID NO.7所示的融合蛋白的同感序列按照上述优化方式得到优化序列的氨基酸为SEQ ID NO.11所示,其编码基因的核苷酸序列为SEQ IDNO.12所示;将SEQ ID NO.9所示融合蛋白的同感序列按照上述优化方式得到的优化序列的氨基酸序列为SEQ ID NO.13所示,其编码基因的核苷酸序列为SEQ ID NO.14所示。
本发明将优化后的同感序列在家蚕表达系统中进行表达,根据基因表达产物ELISA效价结果可见,密码子优化后的同感序列的表达量相比优化前有了显著提高。
本发明获得了H9 HA-Ferritin-C、H5 HA-Ferritin-C突变体,以H9 HA-Ferritin-C、H5 HA-Ferritin-C突变体密码子优化后的基因序列为模板,设计多对引物对保守序列进行定点突变:
将SEQ ID NO.11所示的氨基酸序列按照N40S、N41D、A47T、L51I、M58I、G63N、P83L、P101S、T138K、E181G、N191H、H192Q、D196E、T197A、G236R、I267V、Q304H、D367N、N419S或V469M的氨基酸单位点突变方式获得了多个单位点突变体;
将SEQ ID NO.13所示的氨基酸序列按照V40I、K51R、T52A、K56R、S72R、N100S、H126R、G155E、E186K、D187N、V190I、L191M、G193W、I242M、N289Y、N325S、Y366F、E406G、D462E或Q501H的氨基酸单位点突变方式获得了多个单位点突变体;
本发明将突变后的这些单位点突变体在家蚕表达系统中进行表达,根据表达结果可见:将SEQ ID NO.11所示的氨基酸序列按照N40S、N41D、A47T、N191H、H192Q或D196E的氨基酸单位点突变方式获得的6个突变体的表达产物的效价呈显著提升;
将SEQ ID NO.13所示的氨基酸序列按照V40I、K51R、K56R、V190I、L191M或G193W的氨基酸单位点突变方式获得的6个突变体的表达产物的效价呈显著提升。
基于所确定的部分单位点的突变是有效突变,可以达到提高H9 HA-Ferritin-C-O-M、H5 HA-Ferritin-C-O-M突变体表达量的目的。考虑到氨基酸的排列顺序是蛋白质的一级结构并决定着蛋白质的高级结构,且上述进行的氨基酸单位点突变有部分突变位点的位置可能是相互关联的,本发明进一步进行氨基酸双位点突变。本发明将可以提高表达量的单突变位点H9 HA:N40S、N41D、A47T、N191H、H192Q、或D196E;H5 HA:V40I、K51R、K56R、V190I、L191M或G193W两两组合进行双位点突变,具体如下:
将SEQ ID NO.11所示的氨基酸序列按照N40S-N41D、N40S-A47T、N40S-N191T、N40S-H192Q、N40S-D196E、N41D-A47T、N41D-N191H、N41D-H192Q、N41D-D196E、A47T-N191H、A47T-H192Q、A47T-D196E、N191H-H192Q、N191H-D196E或H192Q-D196E的氨基酸双位点突变方式获得15个双位点突变体;
将SEQ ID NO.13所示的氨基酸序列按照V40I-K51R、V40I-K56R、V40I-V190I、V40I-L191M、V40I-G193W、K51R-K56R、K51R-V190I、K51R-L191M、K51R-G193W、K56R-V190I、K56R-L191M、K56R-G193W、V190I-L191M、V190I-G193W或L191M-G193W的氨基酸双位点突变方式获得15个位点突变体;
本发明将获得的30个双位点突变体分别在家蚕表达系统中进行表达,根据表达结果可见:将SEQ ID NO.11所示的氨基酸序列按照N40S-N41D、N41D-A47T或A47T-H192Q的氨基酸双位点突变方式获得的3个位点突变体的表达产物的效价呈显著提升,其中,将SEQ IDNO.11所示的氨基酸按照N41D-A47T氨基酸双位点突变获得的突变体(所述突变体的氨基酸序列为SEQ ID NO.19所示,其编码基因的核苷酸序列为SEQ ID NO.20所示)的效价提升最为显著;
将氨基酸序列为SEQ ID NO.13所示的氨基酸按照V40I-K51R、K51R-V190I或V190I-G193W中的氨基酸双位点突变方式获得的3个位点突变体的表达产物的效价呈显著提升,其中,将氨基酸序列为SEQ ID NO.13所示的氨基酸按照V190I-G193W氨基酸双位点突变获得的位点突变体(所述突变体的氨基酸序列为SEQ ID NO.21所示,其编码基因的核苷酸序列为SEQ ID NO.22所示)效价提升最为显著。
鉴于部分双位点突变能够有效提升表达量后效价,考虑到氨基酸的排列顺序是蛋白质的一级结构,并决定着蛋白质的高级结构,推测可能是由于进行的氨基酸单位点突变有部分突变点的位置相互靠近彼此关联的,本发明进一步尝试进行氨基酸多位点突变。本发明通过分析糖基化位点,得出6个单突变位点能有效提高目的基因的表达量,因此多位点突变是基于上述获得有效的双位点突变序列的基础之上,通过融合PCR的方法进行多突变位点的定点突变,具体突变方式如下:
将SEQ ID NO.11所示的氨基酸序列按照N40S-N41D-A47T-N191H-H192Q-D196E氨基酸多位点突变方式获得多位点突变体,所述多位点突变体的氨基酸序列为SEQ ID NO.23所示,其编码基因的核苷酸序列为SEQ ID NO.24所示;将SEQ ID NO.13所示的氨基酸序列按照V40I-K51R-K56R-V190I-L191M-G193W氨基酸多位点突变方式获得的多位点突变体,所述多位点突变体的氨基酸序列为SEQ ID NO.25所示,其编码基因的核苷酸序列为SEQ IDNO.26所示。
本发明将获得的两个多位点突变体(SEQ ID NO.23、SEQ ID NO.25)分别在家蚕表达系统中进行表达,根据表达结果可见:所得的两个多位点突变体的表达量相比上述单突变体、双突变体的表达量均有显著提升。本发明进一步将这两个多位点突变体在家蚕表达系统中的表达产物经过初步纯化后采用电镜进行观察,观察结果可见产物大小与预期符合的纳米颗粒,笼状体的直径为12纳米左右,仔细观察可见有天线状突出。
本发明将获得的两个多位点突变体(SEQ ID NO.23、SEQ ID NO.25)编码基因克隆到杆状病毒哺乳动物的表达载体中构建得到呈递基因的重组杆状病毒;将重组杆状病毒呈递给小鼠和鸡,结果发现小鼠和鸡所产生的抗体效价明显高于健康蚕蛹对照和传统疫苗。
因此,本发明所提供的包含融合蛋白的自组装铁蛋白纳米抗原颗粒能应用于制备流感疫苗,其应用方法包括:

或者将所述的融合蛋白编码基因在AcMNPV-昆虫细胞真核表达系统中进行表达,收集并纯化所表达的抗原;优选的,将融合蛋白编码基因克隆到杆状病毒转移载体中构建得到重组杆状病毒转移载体;将重组杆状病毒转移载体与杆状病毒DNA共转染昆虫细胞,获得重组杆状病毒;将重组杆状病毒感染昆虫宿主或昆虫细胞,培养被感染的昆虫细胞或昆虫宿主表达相应的抗原,纯化,即得;
(Ⅲ)还可将所述的融合蛋白编码基因克隆到基因呈递载体上构建得到向脊椎动物细胞或个体中呈递外源基因的重组杆状病毒转移载体,将重组杆状病毒转移载体转染家蚕细胞得到重组病毒;所得到的重组病毒通过注射或口服的方式在动物体内呈递抗原并诱导动物产生抗体。

实施例1 H9 HA-Ferritin、H5 HA-Ferritin原始序列纳米颗粒疫苗的制备与效力检测
1有关溶液和培养基的配置
有关溶液和培养基的配置方法参照相关工具书(Joseph et al.,分子克隆实验指南第三版,2002;奥斯伯,等人,精编分子生物学指南,1998)。
2 H9、H5血凝素蛋白基因序列和铁蛋白基因序列的合成。
为了使流感病毒血凝素与铁蛋白更好的融合表达,利用信号肽分析软件(SignalP)和跨膜结构域分析软件(TMHMM)分别对H9(SEQ ID NO.3)和H5(SEQ ID NO.4)流感病毒血凝素蛋白的氨基酸序列进行分析,分别得出H9血凝素蛋白其信号肽为前18个氨基酸,其胞外结构域为前524个氨基酸。H5血凝素蛋白其信号肽为前16个氨基酸,其胞外结构域为前532个氨基酸。
为了促进流感病毒与铁蛋白融合纳米颗粒的表达效率,并提高可溶表达,将幽门螺杆菌铁蛋白氨基酸序列(SEQ ID NO.1)中第19位天冬酰胺(N)突变为谷氨酰胺(Q),以消除糖基化位点。其中流感病毒血凝素蛋白序列与铁蛋白序列之间由一段连接肽连接(SGG),将铁蛋白氨基酸序列前4个氨基酸去掉,然后将连接肽连在铁蛋白N端第5个氨基酸上。
为了提高目的基因在家蚕杆状病毒真核表达体系中的翻译起始效率,在基因前面加了Kozak序列AAC,为了提高翻译终止效率,终止密码子改为TAA。此外,还去除了基因序列内部的BamHI、EcoRI等限制性酶切位点,在基因上游加上了BamHI,在基因下游加上了EcoRI限制性酶切位点,以便后续克隆到真核转移载体pVL1393中。
将目的基因序列去掉信号肽,利用pET-28a(+)载体上的ATG进行起始起始翻译。此外,还去除了基因序列内部的BamHI、EcoRI等限制性酶切位点,在基因上游加上了BamHI,在基因下游加上了EcoRI限制性酶切位点,以便后续克隆到原核载体pET-28a(+)上。
将上述所设计的流感病毒血凝素基因序列和铁蛋白序列交由相关生物科技有限公司合成。

表9 H9 HA-Ferritin-C-O-M、H5 HA-Ferritin-C-M突变体表达产物的ELISA效价
ELISA结果判定标准:以P/N值(阳性孔OD值减去空白对照孔OD值/阴性孔OD值)大于或等于2.1为阳性,虽然最高的ELISA值在为3200左右,因为本实验是用阈值和稀释倍数作为定量指标的,具体的样本的量因为P/N值的大小不同,还是有所差别的;同样的血凝因为也是二倍稀释,血凝现象可确定的时间也有先后,虽然是同一血凝值,并不代表含量完全一致。在后面的实验中也存在类似的现象而不一一做出说明。

实施例4 H9 HA-Ferritin-C-O-M、H5 HA-Ferritin-C-O-M进行氨基酸双位点突变后的纳米颗粒疫苗制备与效力检测
鉴于实施例3的结果,确定部分位点的突变是有效突变,可以达到提高H9 HA-Ferritin-C-O-M、H5 HA-Ferritin-C-O-M突变体表达量的目的。考虑到氨基酸的排列顺序是蛋白质的一级结构,并决定着蛋白质的高级结构,且实施例3中进行的氨基酸单位点突变有部分突变位点的位置可能是相互关联的,故尝试进行氨基酸双位点突变。本发明将可以提高表达量的单突变位点H9 HA:N40S、N41D、A47T、N191H、H192Q、或D196E;H5 HA:V40I、K51R、K56R、V190I、L191M或G193W两两组合,进行双位点突变,双位点突变是在实施例三获得的单位点突变序列的基础之上,以其(H9 HA-Ferritin-C-O-M、H5 HA-Ferritin-C-O-M)作为模板,利用相应的引物,通过融合PCR的方法进行第二位的定点突变,从而获得双位点突变的目的片段,融合PCR的方法见实施例1。
双突变位点为H9 HA:N40S-N41D、N40S-A47T、N40S-N191T、N40S-H192Q、N40S-D196E、N41D-A47T、N41D-N191H、N41D-H192Q、N41D-D196E、A47T-N191H、A47T-H192Q、A47T-D196E、N191H-H192Q、N191H-D196E或H192Q-D196E共15种组合,所获得的突变体命名为H9HA-Ferritin-C-O-D(N40S-N41D、N40S-A47T、N40S-N191T、N40S-H192Q、N40S-D196E、N41D-A47T、N41D-N191H、N41D-H192Q、N41D-D196E、A47T-N191H、A47T-H192Q、A47T-D196E、N191H-H192Q、N191H-D196E或H192Q-D196E)、H5 HA-Ferritin-C-O-D(V40I-K51R、V40I-K56R、V40I-V190I、V40I-L191M、V40I-G193W、K51R-K56R、K51R-V190I、K51R-L191M、K51R-G193W、K56R-V190I、K56R-L191M、K56R-G193W、V190I-L191M、V190I-G193W或L191M-G193W)突变体。

从表11和表12数据可以看出在同感序列(SEQ ID NO.13)的基础上进行氨基酸双位点突变,所得突变体有三个双突变体(V40I-K51R、K51R-V190I或V190I-G193W)的表达量相比同感序列的表达量有了明显提高。
实施例5 H9 HA-Ferritin-C-O-D、H5 HA-Ferritin-C-O-D进行氨基酸多位点突变后的纳米颗粒疫苗制备与效力检测
基于实施例4的结果考虑到氨基酸的排列顺序是蛋白质的一级结构,并决定着蛋白质的高级结构,推测可能是由于进行的氨基酸单位点突变有部分突变点的位置相互靠近彼此关联的,故尝试进行氨基酸多位点突变。本发明通过分析糖基化位点,得出6个单突变位点能有效提高目的基因的表达量,因此多位点突变是实施例四获得的双位点突变序列的基础之上,以其(H9 HA-Ferritin-C-O-D、H5 HA-Ferritin-C-O-D)为模板,利用相应的引物,通过融合PCR的方法进行多突变位点的突变,从而获得多位点突变的目的片段,融合PCR的方法见实施例1。
为了避免多位点突变在PCR的过程发生重复突变,另外设置两对引物:

5 Western Blotting检测
具体方法同实施例1。Western blotting结果表明,在重组病毒感染后蚕血淋巴样品的上清液中可检测到81kDa(H9 HA-Ferritin)、84kDa(H5 HA-Ferritin)大小的特异性条带(见图4和图5)。
6电镜观察
用1ml注射器吸一定量的1%醋酸铀待用,用另一注射器吸一定数量的蒸馏水。将H9HA-Ferritin-C-O-M6或H5 HA-Ferritin-C-O-M6纳米颗粒蚕血淋巴经过初步纯化后,用悬浮液稀释,将悬浮样品滴在封口膜上,使之形成一个小液珠,用镊子尖端夹住载网,并使带膜的一面朝下,沾取样品,而后用滤纸吸干,再洗去多余的悬浮物,清洗5次。吸干后,将载网摆在1%醋酸铀染液的液滴上,染色3分钟,用滤纸从铜网边缘吸干多余的染液,重复2-3次,待干燥后镜检。结果如图6所示,可见大小与预期符合的纳米颗粒,笼状体的直径为12纳米左右,仔细观察可见有天线状突出。
实施例6 pVLCAG-H9 HA-Ferritin-C-O-M6、pVLCAG-H5 HA-Ferritin-C-O-M6杆状病毒哺乳动物表达用重组病毒的构建和动物实验
1构建pVLCAG载体
pVL1393载体的多克隆酶切位点上游是一段多角体基因启动子(Pph),该启动子上游是一个EcoR V酶切位点,下游多克隆酶切位点位置第一个酶切位点是BamH I,利用这两个酶切位点将Pph切下,并连上CAG启动子,CAG启动子的来源是pCAGGS载体。SV40-polyA终止子来源于pEGFP-N3载体。设计CAG启动子上下游PCR引物,CAG-1F为上游引物,加上一个HincII酶切位点,CAG-1R为下游引物,加上了一个EcoR I酶切位点。以pCAGGS载体为模板将CAG启动子扩增出来并连接到pMD18T载体上,测序验证正确后用HincII和EcoR I双酶切回收。由于,HincII酶切后为平末端,将回收的CAG启动子与用EcoR V和BamH I酶切回收的载体连接,在Amp抗性LB平板上筛选并酶切鉴定最后测序确认后得到连接上CAG启动子的pVL1393载体。利用多克隆位点中NotI和BglII两个酶切位点将与CAG启动子配套的SV40终止子插入。
设计SV40终止子的上下游PCR引物,SV10-1F为上游引物,加上NotI和PstI两个酶切位点,SV10-1R为下游引物,加上BglII酶切位点。以pEGFP载体为模板将SV40终止子扩增下来并连接到pMD18T,测序验证正确后用NotI和BglII酶切回收250bp左右的片段,将该片段同用NotI和BglII处理的插入了CAG启动子的pVL1393载体进行连接,验证正确后即可获得pVLCAG载体,用于将外源基因连同上下游的CAG启动子和SV40终止子在共转染的过程中转移到杆状病毒多角体基因位点,构建向脊椎动物细胞或个体中呈递外源基因的重组杆状病毒转移载体。
2构建呈递报告基因的重组病毒
2.1将H9 HA-Ferritin-C-O-M6、H5 HA-Ferritin-C-O-M6基因克隆到基因呈递转移载体上
将实施例4中带有酶切位点的H9 HA-Ferritin-C-O-M6、H5 HA-Ferritin-C-O-M6基因片段酶切回收连接到同样酶切处理的pVLCAG载体,鉴定正确后获得pVLCAG-H9HA-Ferritin-C-O-M6、pVLCAG-H5 HA-Ferritin-C-O-M6。
2.2构建基因呈递用的重组病毒并大量制备
分别用pVLCAG-H9 HA-Ferritin-C-O-M6和pVLCAG-H5 HA-Ferritin-C-O-M6转移载体用reBmBac共转染BmN细胞获得重组病毒Bm-CAG H9 HA-Ferritin-C-O-M6和Bm-CAG H5HA-Ferritin-C-O-M6,在共转染过程中依然需要pVL1393-Luc作为对照来确定共转染的成功与否,病毒纯化过程同上。
用重组病毒感染5龄起家蚕幼虫,4-5d后收获蚕血淋巴其中含有大量扩增的重组病毒。
将蚕血淋巴用PBS稀释后超声破碎(10s×10次),然后用12000rpm离心10分钟去除细胞碎片,再用15×104g离心3h,去除上清,沉淀用适量PBS重悬获得初步纯化的重组杆状病毒的病毒粒子,这里一般10mL蚕血的重组病毒离心后用2mLPBS重悬,重悬后重组病毒量约为2.5×1012PFU/ML(约为5×1012viral genomes(vg)/mL,病毒拷贝数利用BmNPV病毒DNA骨架序列引物,GJ-1F(CGAACGGAGACGATGGATGTGG)和GJ-1R(GTGCCGAGCGATTGTAAGGGATC)通过荧光定量PCR计算。
3重组病毒在哺乳动物细胞中表达
采用VERO细胞作为基因呈递的目标,将重组病毒Bm-CAG H9 HA-Ferritin-C-O-M6和Bm-CAG H5 HA-Ferritin-C-O-M6各取100MOI的病毒来进行研究。方法步骤如下:
1)在六孔板中接种上VERO细胞(1×106cell/well),37℃贴壁培养8-12h
2)取1×108PFU纯化后的重组病毒Bm-CAG H9 HA-Ferritin-C-O-M6和Bm-CAG H5HA-Ferritin-C-O-M6加到六孔板的细胞中,37℃孵育1h
3)孵育后去掉含有病毒的培养基,换上正常的DMEM含血清培养基,42小时左右处理细胞,收集表达产物,血凝检测效价1:800。
