本发明涉及生物电泳领域，具体涉及一种生物电泳装置、制备方法及含有该生物电泳装置的设备，更具体的，涉及一种可适用多种形态凝胶胶片的生物电泳装置、该生物电泳装置的制备方法以及含有该生物电泳装置的生物电泳设备。
背景技术
蛋白质印迹法(免疫印迹试验)即Western Blot。它是分子生物学、生物化学和免疫遗传学中常用的一种实验方法。其基本原理是通过特异性抗体对凝胶电泳处理过的细胞或生物组织样品进行着色。通过分析着色的位置和着色深度获得特定蛋白质在所分析的细胞或组织中表达情况的信息。Western Blot实验包括电泳与转印等多个实验步骤：电泳是利用带电粒子在电场中发生移动的一种分离方法。DNA或蛋白分子提取得到以后，需要通过电泳技术来检测其数量和质量。自从琼脂糖和聚丙烯酰胺凝胶被引入核酸研究以来，按相对分子质量大小分离DNA或蛋白分子的凝胶电泳技术，已经发展成为一种分析鉴定DNA或蛋白分子的重要实验手段。琼脂糖或聚丙烯酰胺凝胶电泳是基因操作的核技术之一，它能够用于分离、鉴定和纯化DNA或蛋白分子。该技术操作简单而迅速，已经成为许多通用的分子生物学研究方法，如DNA重组、DNA核苷酸序列分析、DNA限制性内切酶分析及限制性酶切作图等的技术基础；转印是将电泳后分离的蛋白质从凝胶中转移到固体载体(例如NC膜)上，电泳设备在使用过程中，需要凝胶样片作为实验载体，广泛使用的凝胶胶片结构形式有两种通用形式，参见图1-图2所示，一种为双面11、12完全平面式结构(参见图1的左右两侧的用于被电泳设备承接的部位13、14)；参见图3-图4所示，另一种为一面平面21，另一面上端带有台阶22的结构(参见图3的左右两侧用于被电泳设备承接的部位23、24)。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明优选的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1
参见图5-图9所示，一种可适用多种形态凝胶胶片的生物电泳装置，包括支架30，支架30上设有U型沟槽31，U型沟槽31兼容配置有两种不同形态的密封条41、42，两种不同形态的密封条可对应承接不同形态的凝胶胶片。
U型沟槽方便配置两条不同形态的U型密封条。两种不同形态的密封条41、42包括短密封条41和长密封条42，短密封条的用于承接凝胶胶片的一面设有台阶凸起411，可以用来对应承接现有市面上的一面为平面另一面上端带有台阶结构的凝胶胶片；长密封条的用于承接凝胶胶片的一面为平面421，可以用来承接现有市面上的双面完全平面式结构的凝胶胶片。U型密封条优选发泡柔性密封材质制成，使密封条本身具有弹性，这样承接凝胶胶片时，能够很好的起到承接又密封的作用。
作为另一种更优选的具体实施方式，支架30上铺设有用于导电的铂金丝，支架的中间端设有用于固定铂金丝的固定件32，固定件设有用于铂金丝穿过的限位孔(未示出)。该固定件的材质和支架的材质可以相同也可以不同，固定件和支架可以一体成型，也可以粘结固定，或者嵌入式的卯榫固定。固定件可以为一个部件形成的固定件，也可以由2个以上的部件形成的固定件。优选固定件为一个部件，且固定件的材质和支架的材质相同，固定件和支架可以一体成型，这样方便独立制备。当不是一体成型时，可以选择机械式的卯榫固定，或者胶粘剂的粘结固定。无论是何种固定方式，固定件的作用在于，用于固定铂金丝，可使铂金丝更牢靠的贴附在支架上，后期对生物电泳装置的清洗过程中也起到保护铂金丝的作用，减少铂金丝因外力折断的可能性。
本生物电泳装置可以根据创新的结构独立制备，也可以对现有设备进行改装得到。
为此，本发明提供一种可适用多种形态凝胶胶片的生物电泳装置的制备方法，包括如下步骤：
S1.在现有生物电泳装置的支架上开设U型沟槽，且降低U型沟槽两侧边高度；
S2.配置两种不同形态的密封条，使两种不同形态的密封条可对应承接不同形态的凝胶胶片。
作为更优选的制备方法，还包括：
S3.在支架的中间端增设固定件，固定件具有用于铂金丝穿过的限位孔。增设的方式可以采用机械式的卯榫固定，或者胶粘剂的粘结固定。
制备方法即提供了一种可以在原有老款产品(即现有生物电泳装置)的基础上，在支架上进行改装的方法，也就是其可以对现有的两种不同的设备(即现有生物电泳装置)进行改装得到。
现有生物电泳装置例如wix minipro、wix-easypro2等。
实施例2
本发明的一种生物电泳设备，其包括实施例1的生物电泳装置和制胶架压紧装置。制胶架压紧装置与生物电泳装置是配套的，两者之间的结构是独立的。 制胶架压紧装置用于制作凝胶胶片，然后将制作好的凝胶胶片再固定在生物电泳装置上。
为此，生物电泳装置包括胶片夹紧机构和胶片抬升机构。
图10示出了含有胶片夹紧机构的结构示意图，本实施例的胶片夹紧机构的组成部分主要有：与支架30两端活动连接的胶片卡板51、支架30中部设的导向孔52，支架30底部设有的导向槽53、支架30上端设有的定位块54。胶片卡板51的内宽度尺寸小于被夹胶片的尺寸总宽度，胶片卡板51为弹性材料。导向槽53两端为封闭的结构。
胶片夹紧机构作用是固定被测电泳胶片(或称凝胶胶片)，为整个电泳过程起到支撑固定密封作用。胶片卡板51置于支架30左右两端，被夹紧的电泳胶片10置于支架30前后两面，支架30中部有导向孔52，下侧有导向槽53，它们共同起到胶片卡板51的导向作用，使胶片卡板51在使用过程中仅可左右滑动，支架30下端导向槽53两端为封闭口，支架30上端设有两个定位块54，两者结构共同起到对胶片卡板51的限位作用，使胶片卡板51仅能在规定范围内左右滑动；在胶片卡板51向内侧滑动后，胶片卡板51依靠自身弹性变形产生的弹力压紧胶片，完成胶片的固定，密封。
本胶片夹紧机构简单易操作，稳定性高，有利于产品的快速可靠操作，极大的节约了时间，提高了工作效率。
参见图11-图13所示，图11的圆圈处示出了本实施例的胶片抬升机构，本实施例的胶片抬升机构主要由胶片抬升支杆61和横向推杆62构成，抬升支杆61可旋转地连接在支架30的底端；横向推杆62的一端固定在胶片卡板51上，横向推杆62的另一端指向抬升支杆61。
支架30的一个主要作用是固定被测电泳胶片，以及为整个电泳过程起到支撑固定密封作用。由于电泳胶片(或称凝胶胶片，又简称胶片)的结构限制，在胶片密封时需要胶片向上方压紧，因此需要本胶片抬升机构对胶片产生抬升作用。胶片卡板51置于支架30左右两端，胶片上的抬升支杆61置于支架30下端，抬升支杆61可做旋转运动，两被被夹紧的胶片10分别置于支架30前后两面，胶片卡板51在胶片夹紧机构中可向左右两侧移动。参见图12所示，当胶片卡板51向内侧移动时，胶片卡板51下方的横向推杆62与胶片上的抬升支 杆61接触，并迫使胶片上的抬升支杆61向上方运动，从而推动胶片10抬升，达到胶片密封固定效果。
如果要使胶片下降，则是上述动作的相反过程。参见图13所示，即是胶片卡板51向外侧移动，胶片卡板51下方的横向推杆62与胶片上的抬升支杆61渐渐脱离接触，胶片上的抬升支杆61在重力作用下向下方运动。
该胶片抬升机构简单易操作，稳定性高，抬升位置准确，稳定。
实施例3
在实施例2的基础上，本实施例的制胶架压紧装置，如图14至图19所示，该制胶架压紧装置包括制胶玻璃71、制胶架扳手72、制胶架主体73、副连杆74、压紧连杆75、压紧密封条76、旋转按手77、弹性压板78、制胶架底座79、第三转轴710、第一转轴711、第二转轴712、第四转轴713、第五转轴714和第六转轴715；制胶架主体73前端卡槽中设有两块制胶玻璃71；制胶架主体73左、右两端均设有制胶架扳手72；制胶架扳手72底端通过第三转轴710与制胶架主体73活动连接；副连杆74底端第四转轴713活动连接在制胶架主体73上；制胶架扳手72与压紧连杆75通过第二转轴712活动连接；副连杆74和压紧连杆75通过第一转轴711活动连接；制胶架底座79下端设有一个压紧密封条76；制胶架主体73下侧设有一个制胶架底座79；制胶架底座79上端设有一个旋转按手77；旋转按手77前端通过第五转轴714活动连接在制胶架底座79上；弹性压板78通过第六转轴715活动连接在制胶架底座79上，弹性压板78夹在旋转按手77与制胶架底座79之间。
其中，制胶架扳手72、副连杆74、压紧连杆75、旋转按手77和弹性压板78均为弹性材质；压紧密封条76为柔性发泡密封材质。
使用状态为：制胶架扳手72采用连杆机构实现制胶架主体73对两块制胶玻璃71的压紧，压紧效果好，可避免凝胶泄露；制胶架底座79上的旋转按手77通过变型凸轮机构对制胶玻璃71进行位置固定，固定效果好，可避免制胶玻璃71平移，具体操作时，先将两块制胶玻璃71对齐放入制胶架主体73，制胶架主体73与制胶架扳手72、副连杆74、压紧连杆75相连形成双摇杆结构，当扳动制胶架扳手72时，制胶架扳手72通过制胶架主体73和副连杆74带动压紧连杆75做摆动运动，当压紧连杆75上方压紧点摆动到与副连杆74共线时即 可实现对制胶玻璃71的夹紧，同时副连杆74与压紧连杆75处于死点位置，压紧连杆75不会自行复位，会保持压紧状态，当拉开制胶架扳手72时，压紧连杆75方能松开；将压紧状态下的制胶架主体73放入制胶架底座79，旋转按手77和弹性压板78均置于制胶架底座79上端，扳动旋转按手77，旋转按手77利用两端面与转轴中心的距离差，在旋转按手77压紧时实现弹性压板78的压下，利用弹性压板78自身弹性形变产生的弹力在旋转按手77松开状态时使弹性压板78抬起，对应制胶架底座79上放有压紧密封条76从而实现制胶玻璃71的压紧与松开，将制胶玻璃71固定后向两块制胶玻璃71间注塑凝胶，制作凝胶胶片。
制胶架压紧装置能够实现的技术效果有：
(1)本制胶架压紧装置采用连杆机构实现制胶架主体对制胶玻璃的压紧，压紧效果好，可避免凝胶泄露；制胶底座通过变型凸轮机构对制胶玻璃进行固定，固定效果好，可避免玻璃移动。
(2)本制胶架压紧装置的平面连杆机构中，各运动副均为面接触，传动时受到的单位面积上的压力较小，且有利于润滑，所以磨损较轻，寿命较长。
(3)本制胶架压紧装置的制胶架主体下端设有一个压紧密封条，密封效果极好，可防止凝胶泄露。
(4)本制胶架压紧装置由于接触面多为圆柱面或平面，制造比较简单，易获得较高的精度。
实施例4
在实施例2或实施例3的基础上，参见图20所示，该生物电泳设备还包括电泳槽80，该电泳槽80在相对的两侧分别内嵌有一根专用管道81，此相对的两根专用管道81用于连通外部的制冷设备。该制冷设备连通两根专用管道后，用于对电泳槽内的缓冲液进行循环制冷，以保证实验过程中的热量能及时散出，保证实验效果。
因为，在电泳实验中，会产生大量热量，热量无法散出会造成实验数据误差加大，严重的会烧毁样品，使得实验失败，现有的常用做法是在实验前准备大量冰块，在实验时将整个电泳槽放置入冰块内，以保证实验过程中的热量能 够有效转移。但是该方法需提前制备大量冰块，且占用空间巨大，大大增加实验人员的低效率工作强度。
因此，为了解决该技术问题，本实施例通过将电泳槽内嵌两根专用管道，用于实验时可外部连通配套的制冷装置，对电泳槽内的缓冲液进行循环制冷，以保证实验过程中的热量能及时散出，保证实验效果。
作为一种优选的实施例，电泳槽内可以一体化内嵌两根相对的专用管道，可以配置连通多种制冷设备。一体化结构便于连通制冷设备，便捷可靠，能够最大程度的简化研究过程。
实施例5
在实施例4的基础上，参见图21-图26所示，电泳槽内放置有样品夹90，有与电泳的正负电极分别对应电连接的两电极片82直接夹在样品夹90上的两侧，使电泳的正负电极83、84直接在样品夹上。样品夹90的两个面所固定的电极板97即构成了电极的正极和负极。
参见图21所示，样品夹90内从上往下依次层叠放置有第一衬托纤维91、第一滤纸92、转移膜93、凝胶94、第二滤纸95、第二衬托纤维96。
在转印实验中，电场强度对电泳速度起着正比作用，电场强度越高，带电颗粒移动速度越快。
参见图24所示，距离为d，当开关k闭合稳定后，电容器两板间电压为U，这时两板间产生的电场强度为:
E＝U/d
当U一定时，当将两极板间的距离由d增大到dˊ时。由上式可知，这时两板间的电场强度变为Eˊ＝U/dˊ，即电场强度减小，反之当减小d时，电场强度增大。
相比于现有的老式转印模块电极间距在4cm左右，其正负电极是设置在两侧往外凸的框架上。本实施例的创新结构在于：将电泳槽内的正负电极通过电极片直接置放于样品夹(转印模块)上，大大减小了电极间的距离一倍以上，使得在同样电压的前提下，可以提供更大的电场强度，从而加快转印速度。
本实施例通过减小电极间距从而加强电场强度，增加带电粒子转移速率，不需要输入更高的电压，结合实施例4的一体化内嵌专用管道，连接配套的制冷设备，可进行快速转印，大大缩短转印时间。
实施例6
在实施例4的基础上，参见图27-图30所示，所述电泳槽还配有一个排液阀门100，在电泳槽80内嵌的专用管道81连通该排液阀门100，该排液阀门100为三通阀，包括第一通口101、第二通口102和第三通口103，第一通口101和第二通口102呈180°相通，第一通口101和第三通口103呈90°相通，第一通口101设有液体单向阀104，第三通口103设有气体单向阀105，液体单向阀104和气体单向阀105呈直角反向设置。
参见图27、图28与29所示，在第一种工作状态下，实验进行时，电泳槽内嵌两根专用管道81，一根专用管道81连通排液阀门100，两根专用管道81还通过制冷管道200配套连通一制冷装置，与电泳槽形成封闭的循环通道；液体单向阀104只单向连通第一通口101和第二通口102；制冷装置对电泳槽内的缓冲液进行循环制冷，以保证实验过程中的热量能及时散出，保证实验效果。此时，排液阀门不影响缓冲液的正常工作。
参见图27、图28与图30所示，在第二种工作状态下，实验结束后，从第三通口103通入空气，气体单向阀105只单向连通第三通孔103和第二通口102，可将制冷管道200内液体(即缓冲液)排出，保护制冷管道200。
由于配套的制冷设备是用于循环电泳槽内的缓冲液从而降低电泳槽内温度，在实验结束后，需要将制冷设备的制冷管道内的缓冲液排出，以避免缓冲液在制冷管道淤积腐蚀堵塞制冷管道。因此本实施例还配有一个排液阀门，阀门内有两个呈直角并相反放置的单向阀，其作用和效果在于：向阀体输送正压时阀体正常通过液体，当输送反向压力时，阀体通过气体，排出制冷管道内残余液体。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施例的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施例或变更均应包含在本发明的保护范围之内。
