Catalog #: CYT-390
Description:
Interleukin-12 Rat Recombinant produced in Sf9 insect cells is a glycosylated disulfide linked heterodimeric polypeptide containing 503 amino acids and having a molecular weight of 70 kDa comprised of disulfide-bonded 35 kDa (p35) and 40 kDa (p40) subunits.
The IL-12 is purified by proprietary chromatographic techniques.
Synonyms:
NKSF, CTL maturation factor (TCMF), Cytotoxic lymphocyte maturation factor (CLMF), TSF, Edodekin-alpha, IL-12.
Source:
Baculovirus.
Amino Acid Sequence:
The sequence of the first five N-terminal amino acids was determined and found to be Arg-Val-Ile-Pro-Val at the p35 subunit and Met-Thr-Glu-Leu-Glu at the p40 subunit.
Purity:
Greater than 95.0% as determined by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized Interleukin 12 in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The protein (1mg/ml) was lyophilized with no additives.
Stability:
Lyophilized Interleukin-12 although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution IL12 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.
Activity:
ED50 range = 0.01-0.05 ng/ml corresponding to a specific activity of 20,000,000-100,000,000IU/mg as determined by the dose dependent secretion of interferon-gamma from PHA and IL-2 activated mouse splenocytes that have been costimulated with PMA. Optimal concentration for individual application should be determined by a dose response assay.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
