Recombinant Murine Interleukin 12a, P35-P40

Cat. No. : Il12a-210M
Product Overview : Recombinant mouse IL-12 produced inSf9 insect cellsis a glycosylated disulfide-linked heterodimeric polypeptide chain of 506 amino acids having a molecular mass of 75 kDa consisting of disulfide-linked 35 kDa (p35) and 40 kDa (p40) subunits. It has been purified by using proprietary chromatographic techniques. It is expressed in Sf9 cells. MW=75kDa.
Description : IL-12 is a potent regulator of cell mediated immune responses and it induces IFN-gamma production by NK and T cells. It is produced by activated monocytes/macrophage cells, B lymphocytes and connective tissue type mast cells. Among its biological activities IL-12 promotes the growth and activity of activated NK, CD4+ and CD8+ cells and induces the development of IFN-gamma producing Th1 cells. Recombinant mouse IL-12 produced in Sf9 insect cells is a glycosylated disulfide-linked heterodimeric polypeptide chain of 506 amino acids having a molecular mass of 75 kDa consisting of disulfide-linked 35 kDa (p35) and 40 kDa (p40) subunits. It has been purified by using proprietary chromatographic techniques.
Source : Sf9 cells.
Purity : Greater than 95% (determined by SDS-PAGE and HPLC analysis).
Specific Activity : NA.
Endotoxin Level : < 0.1 ng per µg of rMu IL-12-p40 (1EU/µg).
Biological Activity : The ED₅₀, as determined by the dose dependent secrtion of interferon-gamma from PHA and IL-2 activated mouse splenocytes that have been co-stimulated with PMA, is 0.01- 0.05 ng/ml.
Formulation : Lyophilized from a sterile-filtered solution with no additives.
Reconstitution : Please Note: Always centrifuge product before opening vial. The lyophilized protein should be reconstituted with distilled, sterile water to a concentration of 0.1-1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
Storage : The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
