Recombinant pig (Sus scrofa) transferrin (NP_001231582.1) (Met 1-Thr 715) was fused with the a polyhistidine tag at the C-terminus.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
1. Measured by its ability to bind human His-TFRC (cat: 11020-H07H) functional ELISA.2. Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. Karey, K.P. et al. (1988) Cancer Research 48:4083. The ED50 for this effect is
The secreted recombinant Sus scrofa (Pig) transferrin comprises 705 amino acids and has a predicted molecular mass of 78.3 kDa. It migrates as an approximately 72 kDa band in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>90 % 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.
