Anti-Interferon gamma抗体(ab9657)

概述

性能

应用

Our Abpromise guarantee covers the use of ab9657 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
WB Use at an assay dependent concentration. To detect hIFN-gamma by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant hIFN-gamma is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
ELISA Use at an assay dependent concentration. Can be paired for ELISA with Mouse monoclonal to Interferon gamma (ab9658).

To detect IFN-gamma by sandwich ELISA (using 100µl/well antibody solution) a concentration of at least 0.5µg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of 0.2 - 0.4 ng/well of recombinant hIFN-gamma.

Neutralising Use at an assay dependent concentration. To yield one-half maximal inhibition [ND50] of the biological activity of hIFN-gamma (50 pg/ml), a concentration of 0.04 - 0.06 ng/ml of this antibody is required.
ICC/IF 1/50.
IHC-P Use a concentration of 0.25 - 0.5 µg/ml.

靶标

  • 功能
    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, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons.
  • 组织特异性
    Released primarily from activated T lymphocytes.
  • 疾病相关
    In 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.
  • 序列相似性
    Belongs to the type II (or gamma) interferon family.
  • 翻译后修饰
    Proteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161.
  • 细胞定位
    Secreted.

Anti-Interferon gamma antibody 图像

  • ab9657 staining Interferon gamma in human cervical squamous cell carcinoma section by Immunohistochemistry (Formalin/PFA fixed paraffin-embedded sections). Tissue underwent heat mediated antigen retrieval in sodium citrate buffer (pH 6.0). The primary antibody was used at 0.25 ug/ml and incubated with sample at 4°C overnight. A HRP-labeled polymer detection system was used with a DAB chromogen.

  • To detect Human IFN-γ by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.5 - 2.0 μg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with a compatible secondary detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human IFN-γ.

All of these antibodies recognise cytokines which are present in inflammed tissue therefore any inflammed tissue would be a good positive control.

A good alternative to tonsil is spleen and also tissue from the digestive tract, for instance colon or small intestine.

Thank you for your enquiry. This antibody is sold at 100 ug per vial. We woudl recommend to reconsitute this in 200 ul of sterile distilled water. This will provide a stock concentration of 0.5 mg/ml. With regards to isotype, this antibody is a polyclo...

Thank you for your enquiry. As far as we know only the pH 6 citrate buffer has been tested as a retrieval buffer for use with ab9657. It is certainly possible that a different pH buffer will also work, however we do not have any experimental data to...
