Recombinant Human NRP1 (NP_001019799.1) isoform b (Met 1-Lys 644), fused with a polyhistidine tag at the C-terminus, was produced in Human Cell.
Lyophilized from sterile PBS, pH 7.4
The secreted recombinant human NRP1 consists of 634 amino acids and has a calculated molecular mass of 71.3 kDa. As a result of glycosylation, rh NRP1 migrates as an approximately 88 kDa band in SDS-PAGE under reducing conditions.
< 1.0 eu per μg of the protein as determined by the LAL method.
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. Centrifuge the vial at 4oC before opening to recover the entire contents.
