CHO-CM HCP ELISA kit 的应用
本试剂盒是用于确定在CHO细胞重组表达产品中CHO宿主细胞蛋白(HCPS)的存在。本试剂盒适合使用的抗体通常发现在无蛋白的条件培养介质相生成。该试剂盒是用于研究和制造使用,不用于人类或动物的诊断应用。
CHO-CM HCP ELISA 试剂盒的英文描述
This assay is intended for use on pharmaceutical products secreted into protein-free CHO growth media. The antibody is raised against, affinity purified, and calibrated with HCPs typically found in CHO protein-free conditioned media. Special procedures were utilized in the generation of these antibodies to insure that low molecular weight and less immunogenic contaminants as well as high molecular weight components would be represented. Our assay validation has determined that the LOD for this kit is <200pg/mL.
CHO-CM HCP ELISA kit 的使用步骤规则
The CHO HCP assay is a sequential, two-site immunoenzymetric assay also termed ELISA. Samples potentially containing CHO proteins are reacted in microtiter strips coated with an affinity purified capture antibody. After a wash step, a horseradish peroxidase enzyme labeled anti-CHO antibody is reacted sequentially forming a sandwich complex of solid phase antibody-CHO protein-enzyme labeled antibody. The microtiter strips are then washed to remove any unbound reactants. The substrate tetramethyl benzidine (TMB) is then reacted. The amount of hydrolyzed substrate is read on a microtiter plate reader and is directly proportional to the concentration of CHO proteins present.
CHO-CM HCP ELISA kit 的保存和稳定性
* All reagents should be stored at 2C to 8C for stability until the expiration date printed.
*Reconstituted wash solution is stable until the expiration date of the kit.
CHO-CM HCP ELISA kit 的使用注意事项
*只用于研究或制造。
*停止反应试剂是0.5M H2SO4。避免接触眼睛,皮肤,和服装。在用本试剂盒的试剂浓度,其他没有被认为是有害的。
*本试剂盒只能由合格的技术人员使用。

文献和实验一、ELISA试剂盒的组成 完整的ELISA试剂盒包含以下各组分: (1)已包被抗原或抗体的固相载体(免疫吸附剂); (2)酶标记的抗原或抗体(结合物); (3)酶的底物; (4) 阴性对照品和阳性对照品(定性测定中),参考标准品和控制血清(定量测定中); (5)结合物及标本的稀释液; (6)洗涤液,在板式ELISA中,常用的稀释液为含0.05%吐温20磷酸缓冲盐水; (7)酶反应终止
运用Cell Based Elisa检测信号通路蛋白和磷酸化蛋白
using Phospho-p38 and Total-p38 antibodies (C). Cell-Based Elisa将小鼠巨噬细胞4/4细胞种在96孔板内,每个孔种5 x 104 cells/cm2细胞。细胞用不同浓度的anisomycin刺激,我们来监测P38 MAPK和JNK两种蛋白的变化。按照试剂盒的实验步骤,分别固定,打孔,猝灭,封闭,然后一抗孵育,二抗孵育,最后显色,用常规的酶标仪读取数值。最后数据再和试剂盒提供的结晶紫核染料结果做纠正,最后得出以上数据。Quantitative
在临床检验中一般采用商品试剂盒进行测定。前文(2.2)已述,ELISA中有三个必要的试剂:免疫吸附剂、结合物和酶的底物等。完整的ELISA试剂盒包含以下各组分:(1)已包被抗原或抗体的固相载体(免疫吸附剂);(2)酶标记的抗原或抗体(结合物);(3)酶的底物;(4)阴性对照品和阳性对照品(定性测定中),参考标准品和控制血清(定量测定中);(5)酶联物(结合物)及标本的稀释液;(6)洗涤液;(7)酶反应终止液。一、免疫吸附剂已包被抗原或抗体的固相载体在低温(2~8℃)干燥的条件下一般可保存6个月
