IRF-2 Antibody (TQ-5) is a mouse monoclonal IgG2a antibody that detects IRF-2 in human samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). IRF-2 plays a crucial role in the regulation of immune responses by acting as a transcriptional repressor of interferon regulatory factor-1, thereby modulating the expression of type I interferons and interferon-inducible genes. This regulatory function is vital for maintaining the balance between immune activation and suppression, which is essential for preventing excessive inflammation and autoimmunity. IRF-2 is primarily located in the nucleus, where IRF-2 binds to specific DNA sequences in the promoters of target genes, influencing their transcriptional activity. Understanding the cellular localization of IRF-2 highlights IRF-2′s role in gene regulation and potential impact on cellular responses to viral infections and other immune challenges. IRF-2 (TQ-5) monoclonal antibody serves as an invaluable tool for researchers studying the intricate mechanisms of immune regulation and the pathophysiology of diseases associated with dysregulated interferon signaling.

Can sc-101069: IRF-2 (TQ-5) monoclonal antibody be used to stain formalin-fixed, paraffin-embedded (FFPE) tissue sections?

Asked by: Germaine
Thank you for your question. Yes, sc-101069: IRF-2 (TQ-5) is recommended for use in IHC with paraffin-embedded sections. We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
