Recombinant human PLA2G1B (NP_000919.1) (Met 1-Ser 148) with a C-terminal polyhistidine tag was expressed.
Predicted N Terminal:
Lyophilized from sterile 10mM Tris, 5mM CaCl2, pH 8.0, 5%~8% trehalose and mannitol.
Measured by its ability to hydrolyze 1-Hexadecanoyl-2-(1-pyrenedecanoyl)-sn-glycero-3-phosphomethanol. The specific activity is >2,500 pmol/min/μg.
The recombinant human PLA2G1B comprises 144 amino acids after removal of the signal peptide, and has a predicted molecular mass of 16.2 kDa. rh PLA2G1B migrates as an approximately 19 kDa band in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>92 % as determined by SDS-PAGE.
Samples are stable for up to twelve months from date of receipt at -70ºC.
Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
