描述

Recombinant Human tPA/Tissue-type plasminogen activator/PLAT Protein is produced by Human cells expression system. The target protein is expressed with sequence (Ser36-Pro562) of human tPA/Tissue-type plasminogen activator/PLAT (Accession #P00750) fused with a 6×His tag at the C-terminus.

标签

C-6×His

纯度

> 95% by SDS-PAGE.

内毒素

< 1 EU/μg of the protein by LAL method.

制剂

Lyophilized from a 0.2 μm filtered solution of 20mM MES,150mM NaCl,0.2mM GaCl2,pH5.5.Contact us for customized product form or formulation.

储存

Store the lyophilized protein at -20°C to -80 °C for long term.
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月；
复溶之后，蛋白溶液在-20°C及以下可保存3个月，在2-8℃可保存1周。

复溶

Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。

背景信息

Tissue-type plasminogen activator (PLAT) is a protein that secreted into extracellular space. PLAT contains five domains:EGF-like domain, fibronectin type-I domain, 2 kringle domains and peptidase S1 domain. It belongs to the peptidase S1family. The main function of this protein is to convert plasminogen into biologically active plasmin. As a protease, PLATplays a crucial role in regulating blood fibrinolysis, maintaining the homeostasis of extracellular matrix and in modulatingthe post-translational activation of growth factors. PLAT is found not only in the blood, where its primary function is as athrombolytic enzyme, but also in the central nervous system (CNS). It participates in a number of physiological andpathological events in the CNS, as well as the role of neuroserpin as the natural regulator of PLAT's activity in theseprocesses. Increased or decreased activity of PLAT leads to hyperfibrinolysis or hypofibrinolysis, respectively. In addition, asa cytokine, PLAT plays a pivotal role in the pathogenesis of renal interstitial fibrosis through diverse mechanisms. Thus, as afibrogenic cytokine, it promotes the progression of kidney diseases.
