作为试剂盒的定量成分,在生产上经多次校准,批次差异管控,特殊冷冻工艺干燥,保证其活性和稳定性。
我们选用进口优质酶标板,保证了固相载体的结合效率和批次差异的稳定性。
3---生产控制
使用全机器生产,排除人工的不稳定性,依靠电子移液器和自动包被机精确加样,控制批内差达到CV﹤8%的要求。
在原料批次性管控的基础上,生产出的试剂盒均会进行标准品,样本,回收率检测,保证批间差CV﹤10%,样品检测数据准确。
酶标板经真空封装机封装。-20℃可保存2年,4度1年半,活性不低于80%。检测抗体和酶试剂4℃保存1年半活性不低于80%。其它试剂均在要求的保存环境下可保存超过1年,试剂盒依然达到检测要求。
选用经过严格把控的塑料耗材,经无菌处理和密封性能测试。在无菌环节下进行试剂分装,包装,保证试剂盒整体的可靠性。
产品在出厂前,所有试剂,整体工作性能,包装均会进行多重检测,保证发给客户的产品无瑕疵。
Precision
● Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
● Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

Sensitivity
Human IL-6 ELISA kit the minimum detection range can be at 0.12 pg/ml.
Nature Proteins Testing Data
Human blood mononuclear cells (1.5 x 106 cells/ml) were cultured in RPMI supplemented with 10% fetal bovine serum, 2 mM/Lglutamine, 100 U/ml penicillin, and 100 μg/ml streptomycin sulfate and stimulated for 1,3,5 days with 15μg/ml PHA-L,Assayed for levels of human IL-6 protein.

Linearity
Spiked human negative serum and cell culture medium(negative) samples to recombinant human IL-6 were serially diluted and assayed for recovery, values between 92-110% show good assay linearity.
