Name : Cynomolgus PLAU/uPA Protein (active form)
Product Source :
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.[Accession | A0A2K5WND1]
Molecular Weight :
The protein has a predicted MW of 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.
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 PBS (pH 7.4). 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 Cynomolgus PLAU (active form) on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Cynomolgus PLAU (active form) is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Cynomolgus PLAU, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human uPAR, hFc Tag with the EC50 of 25.1ng/ml determined by ELISA. SPR Data Cynomolgus uPAR, His Tag immobilized on CM5 Chip can bind Cynomolgus PLAU, His Tag with an affinity constant of 0.033 nM as determined in SPR assay (Biacore T200). Bioactivity Data Measured by its ability to cleave a peptide substrate, N-carbobenzyloxy-Gly-Gly-Arg-7-amido-4-methylcoumarin (Z-GGR-AMC). The specific activity is >2000 pmol/min/μg (QC Test).
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
