活性实验
Perforin 1 (PRF1) is a pore forming cytolytic protein found in the granules of cytotoxic T lymphocytes (CTLs) and NK cells. Upon degranulation, perforin binds to the target cell's plasma membrane, and oligomerises in a Ca2 dependent manner to form pores on the target cell. The pore formed allows for the passive diffusion of a family of pro-apoptotic proteases, known as the granzymes, into the target cell. The activity of recombinant PRF1 was measured by lysis of erythrocytes using a hemolysis assay. A general procedure is as fllows: two-fold dilute the recombinant human PRF1 with 0.9% NaCl, add 50μl a serial dilution of PRF1, 10μl 0.1M CaCl2 to each well, then add 50μl 0.25% rabbit erythrocyte (RaE) to each well and mixed gently. Add 50μl 0.9% NaCl to reaplace PRF1 in control wells. The plate is incubated for 20 hours at 37 ℃, 5% CO2. The results are shown in Figure 2. It was obvious that the minimal effective concentration of PRF1 is 2.5μg/ml.
用法
Reconstitute in ddH2O to a concentration of 0.1-0.5 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%。
