Recombinant sus scrofa IL1B (NP_999220.1) (Ala115-Pro267) was expressed with an initial Met.
Predicted N Terminal:
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells.The ED50 for this effect is typically 0.08-0.4 ng/mL.
The recombinant sus scrofa IL1B consists 154 amino acids and predicts a molecular mass of 17.7 kDa.
< 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.
