Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
This product is an active protein and may elicit a biological response in vivo, handle with caution.
ReconstitutionCentrifuge vial prior to opening. Reconstitute in 100 µl 1x PBS, pH 8.0 to a concentration of 1.0 mg/ml. Do not vortex. Long term storage: Follow reconstitution with further dilution in a buffer containing a carrier protein (example; 0.1% BSA).
- IF 1
FunctionProduced 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, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons.
Tissue specificityReleased primarily from activated T lymphocytes.
Involvement in diseaseIn Caucasians, genetic variation in IFNG is associated with the risk of aplastic anemia (AA) [MIM:609135]. AA is a rare disease in which the reduction of the circulating blood cells results from damage to the stem cell pool in bone marrow. In most patients, the stem cell lesion is caused by an autoimmune attack. T-lymphocytes, activated by an endogenous or exogenous, and most often unknown antigenic stimulus, secrete cytokines, including IFN-gamma, which would in turn be able to suppress hematopoiesis.
Sequence similaritiesBelongs to the type II (or gamma) interferon family.
modificationsProteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161.

The expression profile observed is consistent with what has been described in the literature (PMID: 17142784).
CXCL11 was immunoprecipitated from 0.35mg of THP-1 (human monocytic leukemia cell line) whole cell lysate with ab216157 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab216157 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.
