IL12A & IL12B-1244M
Recombinant p35 subunit of mouse IL12, termed as IL12A (P43431) (Met 1-Ala 215) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; Recombinant p40 subunit of mouse IL12, termed as IL12B (P43432) (Met 1-Ser 335) was fused with
Predicted N Terminal:
Arg 23 & Met 23
Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
1. Measured by its ability to mouse IL12RB2-His in a functional ELISA. 2. Measured in a cell proliferation assay using Anti-CD3-stimulated PBMC. The ED50 for this effect is typically 0.2-1 ng/mL.
The recombinant mouse IL12 heterodimer of IL12A/IL12B, IL12B is Fc chimera, comprises 758 (204 + 554) amino acids and has a calculated molecular mass of 85.9 (23.1 + 62.8) kDa. The apparent molecular mass of rh IL12 heterodimer is approximately 28 & 75 kDa respectively in SDS-PAGE under reducing conditions.
< 1.0 EU per μg of the protein as determined by the LAL method.
>85 % 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.
