SEE ALSO...

TNFα Antibody (C-4) is a mouse monoclonal IgG2a kappa light chain antibody that detects TNFα of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). TNFα (C-4) antibody 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 critical pleiotropic cytokine involved in systemic inflammation and is produced by lymphocytes, neutrophils, and macrophages. TNFα plays a key role in mediating immune responses and inflammation, which is vital for defense against infections and tumors. TNFα monoclonal antibody (C-4) targets a protein that interacts with two main receptors, TNFR1 and TNFR2, which are essential for signaling pathways regulating cell survival, apoptosis, and inflammatory response. Anti-TNFα antibody (C-4) recognizes a target that modulates these processes, making TNFα significant for therapeutic interventions in various inflammatory diseases and cancers. TNFα and TNFβ share approximately 30% amino acid homology and exhibit similar biological activities, highlighting their importance in immune regulation.

what's the difference between sc-133192 and sc-52746? Are they all applicable for IF staining of rat liver tissue?

Asked by: Chuman
Thank you for your question. sc-133192 is raised against amino acids 77-233 of TNFα of human origin. sc-133192 is recommended for detection of TNFα of human origin by WB, IP, IF and ELISA. sc-52746 is raised against purified full length native TNFα of human origin. sc-52746 is recommended for detection of natural and recombinant TNFα of mouse, rat and human origin by WB, IP, IF, IHC(P), FCM and ELISA; also reactive with additional species, including and Guinea pig, Chimpanzee, Cynomolgus and Rhesus monkey; non cross-reactive with TNFβ or lymphotoxin.

Is a blocking peptide for this product available?

Asked by: dragonfly
Thank you for your question. This mouse monoclonal antibody, TNFα (C-4): sc-133192 is not raised against a peptide so no blocking peptide is available. The antibody is raised against amino acids 77-233 of TNFα of human origin.
