PPACKII is a specific and irreversible inhibitor of glandular and plasma kallikreins [1].
Human tissue kallikreins (hKs) are a class of secreted serine proteases that involved in the release of vasodepressor peptides or kinins from a plasma substrate. Kallikrein has diverse expression patterns and physiological roles. Kallikrein has been primarily known as cancer biomarkers. Kallikrein has been implicated in many cancer-related processes, such as cell-growth regulation, angiogenesis, invasion and metastasis. Kallikrein could promote or inhibit neoplastic progression individually and/or with the interaction in cascades with other hKs and proteases [2].
PPACKII prevented apolipoprotein proteolysis in dextran sulfate-precipitated human plasma LDL and inhibited serum atrial natriuretic peptide cleavage at micromolar concentrations [1]. It has been reported that PPACKII inactivated the amidolytic activity of native human Hageman Factor (Factor XII) at 5.3 μM [3].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
