Product Name:
Recombinant Rat IL12A & IL12B Protein, His-tagged
Product Overview:
Recombinant rat IL23A (NP_569094.1) (Met1-Ala196) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; Recombinant rat IL12B (EDM04146.1) (Met1-Ser335) was expressed with a polyhistidine tag at the C-terminus, constructed the p
Predicted N Terminal:
Val 22 & Met 23
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
Measured by its ability to induce IL17 secretion by mouse splenocytes. The ED50 for this effect is 2-15 ng/mL.
Molecular Mass:
The recombinant rat IL23A & the rat IL12B comprises 510 (186+324) amino acids and has a calculated molecular mass of 58.2 (21+37.2) KDa. The apparent molecular mass of the rat IL23A & the rat IL12B heterodimer is approximately 47.08, 43.29, 27.67 and 24.75 KDa respectively in SDS-PAGE.
< 1.0 EU per μg of the protein as determined by the LAL method.
(17.9+53.5+2.9+23.8) % 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.
