Recombinant Cynomolgus PLAU/uPA Protein (active form) is expressed from HEK293 with His tag at the C-Terminus.It contains Ser21-Leu430, which consists of two chains: Long chain A and chain B. The long chain A is further cleaved to yield a short chain A and N-Terminus fragment.

状态
Lyophilized
溶解方式
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/mL is recommended. Dissolve the lyophilized protein in distilled water.
缓冲液
Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.
储存条件
-20 °C,-80 °C
储存方法
-20 to -80°C for 12 months as supplied from date of receipt.,-80°C for 3-6 months after reconstitution.,2-8°C for 2-7 days after reconstitution.,Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Plasminogen activator, urokinase (uPA) is a secreted serine protease whose Dysregulation is often accompanied by various cancers. PLAU inhibition could suppress tumor growth. Collectively, PLAU is necessary for tumor progression and can be a diagnostic and prognostic biomarker in HNSCC.
分子量
47.23 kDa. Due to protein lysis and glycosylation, the protein migrates to 23-25 kDa (long chain A), 35-40 kDa (chain B) and 50-60 kDa (long chain A&chain B) based on Tris-Bis PAGE result.
