  Figure. The binding activity of LpPLA2 with PTPRN.
  Phospholipase A2, Lipoprotein Associated (LpPLA2) also known as platelet-activating factor acetylhydrolase (PAF-AH) is a phospholipase A2 enzyme. LpPLA2 is platelet-activating factor (PAF) acetylhydrolase, a secreted enzyme that catalyzes the degradation of PAF to inactive products by hydrolysis of the acetyl group at the sn-2 position, producing the biologically inactive products LYSO-PAF and acetate. Besides, Protein Tyrosine Phosphatase Receptor Type N (PTPRN) has been identified as an interactor of LpPLA2, thus a binding ELISA assay was conducted to detect the interaction of recombinant human LpPLA2 and recombinant human PTPRN. Briefly, LpPLA2 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100uL were then transferred to PTPRN-coated microtiter wells and incubated for 2h at 37℃. Wells were washed with PBST and incubated for 1h with anti-LpPLA2 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37℃. Finally, add 50µL stop solution to the wells and read at 450nm immediately. The binding activity of LpPLA2 and PTPRN was shown in Figure 1, and this effect was in a dose dependent manner.

  

  用法

  Reconstitute in 20mM Tris, 150mM NaCl (pH8.0) 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%。
