Description

核酸扩增反应的容器
技术领域
本发明与核酸扩增反应有关,特别涉及一种核酸扩增反应使用的容器。
背景技术
所谓的核酸扩增反应,是指反复利用相同的操作程序,给合特定的聚合酶,使核酸能扩增的技术。常见的聚合酶链锁反应(polymerase chain reaction,PCR)、反转录聚合酶链锁反应(reverse transcription polymerase chain reaction,RT-PCR)、实时聚合酶链锁反应(real-time polymerase chain reaction,real-time PCR),均属于核酸扩增反应的技术。
其中,聚合酶链锁反应是指扩增特定脱氧核醣核酸片段的技术。反转录聚合酶链锁反应是指先利用信使核醣核酸(mRNA)转录得到脱氧核醣核酸(DNA),再用此脱氧核醣核酸进行前述聚合酶链锁反应的技术。实时聚合酶链锁反应是指在聚合酶链锁反应的过程中,利用荧光探针或染料半定量检测的技术,又称定量聚合酶链锁反应(quantitativePCR)。前述多种技术,都必须用到聚合酶链锁反应的技术。
另外,有些较新颖的技术,如滚环扩增法(Rolling Circle Amplification,RCA)、环介导等温扩增法(Loop Mediated Amplification,LAMP)、核酸序列依赖性扩增法(Nucleic Acid Sequence Based Amplification,NASBA)、核酸三方交叉(Three WayJunction,TWJ),也必须用到聚合酶链锁反应技术。
进行聚合酶链锁反应时,会将脱氧核醣核酸与引物混合在缓冲溶液中,利用90摄氏度左右的温度,使脱氧核醣核酸的双链分离;接着利用50摄氏度左右的温度,使引物黏附在脱氧核醣核酸的特定位置;再利用70摄氏度左右的温度,使黏附在脱氧核醣核酸上的引物延伸。如此步骤重复,能复制特定的脱氧核醣核酸片段。
目前用来进行前述加热过程的装置,根据价格高低,有许多类型。其中较便宜的类型,是在容器(通常是试管)两端设置加热装置,其中一个加热装置固定加热到90摄氏度,另一个加热装置固定加热到50摄氏度。容器中的溶液,便会因温差而产生对流,让溶液中的脱氧核醣核酸和引物在90摄氏度与50摄氏度的温度之间循环,以进行聚合酶链锁反应。
然而,以往的加热装置,通常是金属块,上面有供容器放置的凹槽,凹槽的形状与容器相符。当容器放在加热装置上,将加热装置的温度升高至适当温度,便能对容器加热。此种缺点是,凹槽在实际制作中,无法完全和容器相符;也就是说,凹槽会有小部分凸出,也有小部分凹陷。其中凸出的部分,会造成周围的部分无法和容器接触,凹陷的部分,会造成该处无法和容器接触。如此容器便无法均匀受热,影响聚合酶链锁反应的,也就是核酸扩增反应的反应速度。
发明内容
本发明的一个方面在于提供一种核酸扩增反应的容器,利用紧配合的技术,让容器能均匀受热。
根据本发明的一种实施方式,一种核酸扩增反应的容器包含毛细管与导热套。其中导热套套在毛细管的外侧,用于将热能均匀地提供给毛细管。
根据本发明的核酸扩增反应的容器,其中,导热套为环体。
根据本发明的核酸扩增反应的容器,其中,导热套为扣件。
根据本发明的核酸扩增反应的容器,其中,导热套为C形。
根据本发明的核酸扩增反应的容器,其中,毛细管的材质为塑料。
根据本发明的核酸扩增反应的容器,其中,毛细管的材质为聚碳酸脂。
根据本发明的核酸扩增反应的容器,其中,导热套的材质为金属。
根据本发明的核酸扩增反应的容器,其中,导热套的材质是铁。
根据本发明的核酸扩增反应的容器,其中,毛细管包含环槽,环槽用于容纳且定位导热套。
据此,与现有技术相比,当热能传导至导热套时,能均匀地对毛细管加热。
附图说明
图1示出本发明一种实施方式的容器的立体图。
图2示出图1的容器的分解图。
图3示出沿着图1之A-A处的剖视图。
具体实施方式
图1示出本发明一种实施方式的容器的立体图。图2示出图1容器的分解图。如图所示,容器包含毛细管100与导热套200。其中导热套200套在毛细管100的外侧。
图3示出沿着图1的线A-A的剖视图。前述导热套200套在毛细管100的一端110,此端110为封闭端。使用时,毛细管100置入热源300的凹槽310内,利热源300对导热套200加热,经由热交换,能利用热源300提供的热能对毛细管100的端110加热。控制毛细管100此端110的温度大约在90摄氏度,另一端则利用环境温度降温至大约50摄氏度,便能在毛细管100内进行核酸扩增反应。
由于导热套200套在毛细管100外侧,因此导热套200的热能可以均匀地传导到毛细管100。且毛细管100不与热源300直接接触,不会有受热不均的情况。利用导热套200使毛细管100受热均匀,能提升核酸扩增反应的反应速度。
参照图2,其中毛细管100可以包含环槽120。环槽120位于此端110,供容纳且定位导热套200。
其中导热套200可以是环体,且导热套200的内径与毛细管100的外径相符,使导热套200能套在毛细管100外。另外,导热套200也可以是扣件,且导热套200的内径小于或等于毛细管100的外径,让导热套200能变形紧套在毛细管100外。详细地说,当导热套200为扣件时,导热套200的形状可以是C形,也就是说,导热套200可以是C形扣。
其中导热套200套在毛细管100的技术中,当导热套200为环体时,导热套200的内侧会完全与毛细管100的外侧接触。当导热套200为扣件时,导热套200的内侧会完全与毛细管100的外侧接触。
其中毛细管100的材质为塑料,更进一步地说,毛细管100的材质是聚碳酸脂(polycarbonate,PC)。导热套200的材质为金属,更进一步地说,导热套200的材质是铁。前述毛细管100和导热套200的材质,根据耐热度和强度等条件比较下,是符合需求且较为低价的材质,能确实地降低产品价格。
