CD28 Antibodies

Santa Cruz Biotechnology features a diverse variety of CD28 monoclonal antibodies for research in immunology and cell signaling. CD28 monoclonal antibodies are compatible with multiple research applications, including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). CD28 is a critical co-stimulatory receptor found on T cells, playing a vital role in T cell activation and survival. CD28 enhances the immune response by providing necessary signals for T cell proliferation and cytokine production, making it essential for effective immune function. Understanding CD28 function in immune regulation is crucial for developing therapies for autoimmune diseases and improving cancer immunotherapy. CD28 research continues to reveal new insights into T cell biology and immune system regulation. Investigating CD28 signaling pathways helps illuminate potential therapeutic targets for immune-related disorders. CD28 monoclonal antibodies from Santa Cruz Biotechnology enable researchers worldwide to advance scientific understanding of immune system function and disease treatment.
