CD4 Monoclonal Antibody (RPA-T4), Brilliant Ultra Violet™ 615, eBioscience™, Invitrogen™

Description

• The RPA-T4 mAb reacts with human CD4, a 59 kDa cell surface receptor expressed by a majority of thymocytes, subpopulation of mature T cells (T-helper cells) and in low levels on monocytes
• CD4 is a receptor for the human immunodeficiency virus (HIV)
• RPA-T4 blocks HIV binding and mixed lymphocyte reaction
• The RPA-T4 antibody recognizes a different epitope than the OKT4 mAb, and these antibodies do not cross-block binding to each other's respective epitopes
• Applications Reported: This RPA-T4 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This RPA-T4 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells
• This may be used at 5μL (0.25μg) per test Brilliant Ultra Violet 615 (BUV615) is a tandem dye that emits at 615 nm and is intended for use on cytometers equipped with an Ultraviolet (355 nm) laser
• Please make sure that your instrument is capable of detecting this fluorochrome
• When using two or more Super Bright, Brilliant Violet, Brilliant Ultra Violet, or other polymer dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (SB-4401-42) or Brilliant Stain Buffer (00-4409-75) to minimize any non-specific polymer interactions
• Light sensitivity: This tandem dye is sensitive to photo-induced oxidation
• Please protect this vial and stained samples from light
• Excitation: 350 nm; Emission: 615 nm; Laser: Ultraviolet Laser
• The CD4 antigen is involved in the recognition of MHC class II molecules and is a co-receptor for HIV
• CD4 is primarily expressed in a subset of T-lymphocytes, also referred to as T helper cells, but may also be expressed by other cells in the immune system, such as monocytes, macrophages, and dendritic cells
• At the tissue level, CD4 expression may be detected in thymus, lymph nodes, tonsils, and spleen, and also in specific regions of the brain, gut, and other non-lymphoid tissues
• CD4 functions to initiate or augment the early phase of T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase, Lck
• It may also function as an important mediator of direct neuronal damage in infectious and immune-mediated diseases of the central nervous system
• Multiple alternatively spliced transcripts have been identified in this gene [RefSeq, July 2017].
