TNFα Antibody (J1D9) is a mouse monoclonal IgG1 kappa light chain antibody that detects TNFα in mouse, rat, and human samples through western blotting (WB), immunoprecipitation (IP), and flow cytometry (FCM). Anti-TNFα antibody (J1D9) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Tumor necrosis factor alpha (TNFα), also known as cachectin, is a crucial pro-inflammatory cytokine that plays a significant role in immune response and inflammation. TNFα is primarily produced by immune cells such as macrophages, lymphocytes, and neutrophils, and is essential for regulating various physiological processes, including cell proliferation, differentiation, and apoptosis. TNFα is involved in the pathogenesis of several inflammatory diseases, making TNFα a key target for therapeutic intervention. TNFα′s ability to bind to TNF receptors 1 and 2 on target cells is critical for mediating effects, including apoptosis induction in tumor cells, which requires receptor expression. Understanding TNFα function and interactions with other proteins in the immune system is vital for developing strategies to modulate TNFα activity in disease contexts.

can you please elaborate the application of SC-33639 HRP antibody?

Asked by: manoj
Thank you for your question. The HRP-conjugated version of Anti-TNFα Antibody (J1D9): sc-33639 can be used for WB, IHC(P) and ELISA and does not require a secondary detection antibody.

Can TNFα (J1D9): sc-33639 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: Professor Griffin
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, TNFα (J1D9): sc-33639 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.
