    SIRP-α/β1 Antibody (E-7) is a mouse monoclonal IgG1 kappa light chain antibody that detects SIRP-α/β1 protein of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). SIRP-α/β1 (E-7) antibody is available as a non-conjugated anti-SIRP-α/β1 monoclonal isotype antibody. The SIRP family, which includes SIRP-α and SIRP-β1, plays a crucial role in regulating immune responses and cellular signaling. SIRP-α is primarily located on the cell surface and mediates interactions with CD47, a "don′t eat me" signal that inhibits phagocytosis by macrophages. This interaction maintains immune tolerance and prevents premature clearance of healthy cells. SIRP-α expression on immune cells, particularly in tumor microenvironments, can significantly influence immunotherapy efficacy by shielding cancer cells from immune detection. SIRP-β1, while sharing structural similarities with SIRP-α, lacks the cytoplasmic signaling domain, suggesting distinct roles in immune regulation. Anti-SIRP-α/β1 antibody (E-7) effectively detects these proteins, making this reagent invaluable for researchers studying immune modulation and potential therapeutic targets in cancer and other diseases.
