Recombinant Human CPA4 Protein, His-tagged

Cat.No.: CPA4-7970H
Product Overview: Recombinant Human Carboxypeptidase A4 /CPA4 Protein (rh CPA4 / Carboxypeptidase A4) Gly 17 - Tyr 421 (Accession # AAH52289) was produced in human 293 cells (HEK293).
Source: HEK293
Species: Human
Tag: His
Predicted N Terminal: Gly 17
Form: Lyophilized from sterile 50 mM Tris, 150 mM NaCl, pH 7.5, 10% Trehalose.
Bio-activity: Measured by its ability to cleave the colorimetric peptide substrate Ac-Phe-Thiaphe-OH in the presence of 5,5"Dithio-bis (2-nitrobenzoic acid) (DTNB). The specific activity is >3000 pmol/min/ug.
Molecular Mass: Human Carboxypeptidase A4, His Tag is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 46.4 kDa. The reducing protein migrates as 48 kDa in SDS-PAGE due to glycosylation.
Endotoxin: Less than 1.0 EU per μg by the LAL method.
Purity: >95% as determined by SDS-PAGE.
Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
Storage: Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
