活性实验
Inter Alpha-Globulin Inhibitor H4 (ITIH4) is secreted into the blood, where it is cleaved by plasma kallikrein into two smaller forms. ITIH4 has been detected only in liver, and it seems to be upregulated during surgical trauma.It may also play a role in liver development or regeneration. Besides, Tau Protein (MAPT) has been identified as an interactor of ITIH4, thus a binding ELISA assay was conducted to detect the interaction of recombinant human ITIH4 and recombinant human MAPT. Briefly, ITIH4 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100 ul were then transferred to MAPT-coated microtiter wells and incubated for 2h at 37℃. Wells were washed with PBST and incubated for 1h with anti-ITIH4 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 5 times. With the addition of substrate solution , wells were incubated 15-25 minutes at 37℃. Finally, add 50 µL stop solution to the wells and read at 450 nm immediately. The binding activity of ITIH4 and MAPT was shown in Figure 1, the EC50 for this effect is 0.18 ug/mL.
用法
Reconstitute in 10mM PBS (pH7.4) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
储存
避免反复冻融。2-8°C不超过一个月，-80°C不超过12个月。
稳定性
热稳定性以损失率显示。损失率是由加速降解试验决定，具体方法如下：在37°C孵育48小时，没有显著的降解或者沉淀产生。保质期内，在适当的条件下存储，损失率低于5%。
