北京* IFN-γ（重組小鼠γ-干擾素）細胞因子 現貨供應

 Synonyms:
Immune Interferon, type II interferon, T cell interferon, MAF, IFNG, IFG, IFI, IFN-gamma.

 Introduction:
IFN-gamma produced by lymphocytes activated by specific antigens or mitogens.
IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions, it is a potent activator of macrophages, and has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons.

 Description:
Interferon-gamma Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 134 amino acids and having a molecular mass of 15601 Dalton.
The IFN-gamma is purified by proprietary chromatographic techniques.

 Source:
Escherichia Coli.

 Physical Appearance:
Sterile Filtered White lyophilized （freeze-dried） powder.

 Formulation:
Lyophilized from a 0.2μm filtered concentrated （1mg/ml） solution in PBS, pH 7.4.

 Solubility:
It is recommended to reconstitute the lyophilized Interferon-gamma in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability:
Lyophilized Interferon-gamma although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFN-gamma 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.

 Purity:
Greater than 95.0% as determined by:
（a） Analysis by RP-HPLC.
（b） Analysis by SDS-PAGE.

 Amino acid sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Met-His-Gly-Thr-Val.

Biological Activity:
The specific activity as determined by the cytopathic affect inhibition assay with murine NIH 3T3 cells chalenged with EMC virus was < 0.1 ng/ml, corresponding to a specific activity of 1 x 10⁷ Units/mg.
