Fyn Antibody (G-4) is a mouse monoclonal IgG1 antibody that detects Fyn in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). Fyn is a member of the Src family of non-receptor tyrosine kinases, which play a crucial role in various cellular processes, including T-cell receptor signaling, cell proliferation, and differentiation. Fyn protein is primarily located in the cytoplasm and can translocate to the plasma membrane upon activation, which is essential for mediating signaling pathways that regulate immune responses. This dynamic localization allows Fyn to interact with various signaling molecules and adapt to different cellular contexts, thereby influencing processes such as cytoskeletal organization and cell adhesion. Anti-Fyn antibody (G-4) is particularly valuable for researchers studying T-cell signaling and its implications in immune system function and related diseases, making this tool indispensable for advancing our understanding of cellular signaling mechanisms.

I need to use an antibody to detect the protein in samples of porcine origin. Do you know if Fyn (G-4): sc-271293 mouse monoclonal antibody will work?
