Description

一种可重复利用的按压式ELISA上样装置
技术领域
本发明涉及一种科研时应用于ELISA的装置,尤其涉及一种可重复利用的按压式ELISA上样装置。
背景技术
酶联免疫吸附实验(ELISA),是常见的分子生物学实验之一,广泛用于学校及科研机构,其原理是将已知的抗原或抗体吸附在固相载体表面,使酶标记的抗原抗体反应在固相表面进行,该技术可用于检测大分子抗原和特异性抗体等,具有快速、灵敏、简便、载体易于标准化等优点。常用的ELISA试剂盒多为96孔板,当大样本用于该实验检测时,从上样的第一孔至最后一孔,耗时较长,误差增加,更无法保证每孔的反应时间相一致,极大的干扰了实验结果;除标准品和样本每孔所加内容不同之外,剩下的一抗工作液、酶标抗体工作液、底物工作液和最后的终止液,均为每孔等量等内容液体。因此,设计本装置,实现同内容等量液体的同时加入,极大的缩短了上样时间,更有利于减少人为操作引起的实验误差,对提高实验的效率和准确性起到有力的推动作用。
发明内容
本发明的目的是针对现有操作具有不稳定性、耗费时间较长、浪费资源等问题,提供一种可重复利用的按压式ELISA上样装置。
本发明的目的是通过以下技术方案实现的:一种可重复利用的按压式ELISA上样装置,该装置包括多个上样管和外架;外架开有多个镂空孔,镂空孔呈矩阵排布,与96孔板对应;上样管的前端嵌入于镂空孔内;所述上样管包括外置套管、套管内活塞、套头底座、单向阀片和顶盖;套管内活塞一端位于外置套管内,与外置套管过盈配合,另一端延伸到外置套管外;所有上样管内的套管内活塞外延高度一致;所述套管内活塞开有中心通孔,中心通孔顶部通过顶盖密封;外置套管下部安装有单向阀片,单向阀片下方为用于存储待上样液体的容置空间;外置套管下端通过套头底座密封。
进一步地,还包括按压板,按压板置于套管内活塞上方。
本发明的有益效果是:针对目前科研进行ELISA实验时的操作方法进行整合及重新设计,利用目前的科技成果进行组装,可以在科研过程中提高效率和一致性,并且节约成本及减少资源的浪费,适用于各院校及科研机构进行实验操作,易于推广。

具体实施方式
如图1-3所示,一种可重复利用的按压式ELISA上样装置,该装置由多个上样管和外架10组成;外架10开有多个镂空孔11,镂空孔11呈矩阵排布,与96孔板对应;上样管的前端嵌入于镂空孔11内。所述上样管包括外置套管1、套管内活塞2、套头底座4、单向阀片5和顶盖7;套管内活塞2一端位于外置套管1内,与外置套管1过盈配合,另一端延伸到外置套管1外;所有上样管内的套管内活塞2外延高度一致。所述套管内活塞2开有中心通孔,中心通孔顶部通过顶盖7密封;外置套管1下部安装有单向阀片5,单向阀片5下方为用于存储待上样液体6的容置空间。外置套管1下端通过套头底座4密封。
上述装置可以通过常规的板对所有套管内活塞2进行按压,也可以设置配套的按压板8。
该装置工作过程如下:
将外架置于96孔板9上方,将套管1嵌入镂空孔11内固定,然后将按压板8置于套管上方,去除每管的套头底座4,对准上样孔,然后用力按压,套管内活塞2下压,使管内阀门片5开放,待上样液体同时注入96孔板9的每孔中。
为防止出现个别液体未全部注入孔中的情况出现,还可通过手动按压未尽液体的套管内活塞2,确保待用液体全部注入孔中。
此外,同一类液体上样结束后,将软性底座4套回,将套管内活塞2回拉至初始位置,然后将顶盖7打开,继续往管腔内加入下一步所需量的液体,全部加完后,待上一步实验反应结束后,依照上面所述方法,一起加样。
