Name : Human PLAU/uPA Protein (pro form)

Product Source :
Recombinant Human PLAU/uPA Protein (pro form) is expressed from HEK293 with His tag at the C-Terminus. It contains Ser21-Leu431.[Accession | P00749-1]

Molecular Weight :
The protein has a predicted MW of 47.5 kDa. Due to glycosylation, the protein migrates to 52-60 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC

Formulation :
Lyophilized from 0.22μm filtered solution in 25mM HEPES, 150mM NaCl (pH 7.5). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-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.

Product Concentration :
Tris-Bis PAGE Human PLAU (pro form) on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human PLAU (pro form) is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human PLAU, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Human uPAR, hFc Tag with the EC50 of 2.4ng/ml determined by ELISA.

Background :
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.

Synonyms :
PLAU; Urokinase; ATF; UPA; URK; u-PA; BDPLT5; QPD
