 IL12A & IL12B Protein Product Information
Synonym:CLMF,CLMF2,IL-12A,IL-12B,IL12,IMD28,IMD29,NFSK,NKSF,NKSF1,NKSF2,P35
Protein Construction:A DNA sequence encoding the p35 subunit of human IL-12, termed as IL12A (NP_000873.2) (Met1-Ser219) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1 ; A DNA sequence encoding the p40 subunit of human IL-12, termed as IL12B (NP_002178.2) (Met1-Ser328) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the heterodimer was purified.
Species:Human
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
