Synonyms

Urokinase, PLAU, ATF, UPA, URK, u-PA, BDPLT5, QPD

Source

Human PLAU, His Tag (activated by trypsin) (PLU-H5228) is expressed from human 293 cells (HEK293). It contains AA Ser 21 - Leu 431 (Accession # P00749-1).

Predicted N-terminus: Ser 21 & Lys 156 & Ile 179

Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version

This protein carries a polyhistidine tag at the C-terminus.

The active form of Human PLAU is a disulfide-linked heterodimer composed of long chain A (Ser 21 - Phe 177) and chain B (Ile 179 - Leu 431) with calculated MW of 17.8 kDa and 29.2 kDa. The long chain A is further cleaved to yield a short chain A (Lys 156 - Phe 177) and N-terminal fragment (Ser 21 - Lys 155) with calculated MW of 15.3 kDa. The protein migrates as 31-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 25 mM HEPES, 150 mM NaCl, pH7.5 with trehalose as protectant.
