The Mouse CD4 Monoclonal Antibody PE-Cyanine5.5 Conjugated (GK1.5) is a valuable tool for research in immunology and cell biology. This antibody specifically targets the CD4 molecule, a key cell surface marker involved in immune responses and T cell activation. By conjugating PE-Cyanine5.5 to the antibody, it enables fluorescent detection and analysis of CD4 expression in various cell types.CD4, a glycoprotein found on the surface of helper T cells, plays a pivotal role in coordinating immune responses by interacting with major histocompatibility complex (MHC) class II molecules. The GK1.5 antibody, derived from mouse hybridoma cells, recognizes CD4 with high specificity and sensitivity, allowing for precise identification and characterization of CD4-expressing cells.
Researchers can utilize this antibody for flow cytometry, immunofluorescence, and other techniques to study T cell subsets, immune function, and diseases such as HIV/AIDS, autoimmune disorders, and infectious diseases. The PE-Cyanine5.5 conjugation enhances the detection sensitivity and multiplexing capabilities, making it a versatile tool for studying immune cell populations and responses in both basic and clinical research settings.

Background:
CD4 is a 55 kD protein also known as L3T4 or T4. It is a member of the Ig superfamily, primarily expressed on most thymocytes, a subset of T cells, and weakly on macrophages and dendritic cells. It acts as a coreceptor with the TCR during T cell activation and thymic differentiation by binding MHC class II and associating with the protein tyrosin kinase, lck.
