Introduction
Active IL-12 is a p70 disulphide-linked dimer composed of p35 and p40 subunits. The protein is a pleiotropic cytokine produced primarily by antigen presenting cells and has multiple effects on T lymphocytes and natural killer cells in terms of stimulating cytotoxicity, proliferation, production of other cytokines and Th1 subset differentiation.
Description
IL-12 p40 human Recombinant produced in Nicotiana benthamiana plant is a glycosilated polypeptide chain containing 312 amino acids, 23-328 aa (molecular formula C1575H2420N424O490S12).
IL-12 p40 is fused to a 6-His-tag at the N-terminal having the total molecular mass of 35.5kDa however as a result of potential glycosylation, the molecular mass could be approximately 40kDa by SDS PAGE under reducing conditions.
IL-12 p40 IS purified by standard chromatographic techniques.

Nicotiana benthamiana plant
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from 1mg/ml solution in 20 mM PBS buffer pH 7.4.
Solubility
It is recommended to reconstitute the lyophilized IL-12 p40 in sterile 18M?-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized IL-12 p40 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-12 p40 should be stored at 4°C between
2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
