CD4 Monoclonal Antibody (SK3 (SK-3)), Super Bright™ 436, eBioscience™, Invitrogen™

Description

• Description: The SK3 monoclonal antibody reacts with human CD4, a 59-kDa cell surface receptor expressed by a majority of thymocytes, a subpopulation of mature T helper cells, and at low levels on monocytes
• CD4 is a receptor for the human immunodeficiency virus (HIV)
• SK3 blocks HIV binding and mixed lymphocyte reaction
•  The SK3 and  RPA-T4 monoclonal antibodies do not cross-block binding, suggesting recognition of distinct epitopes
• Applications Reported: This SK3 (SK-3) antibody has been reported for use in flow cytometric analysis
• Applications Tested: This SK3 (SK-3) antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells
• This can be used at 5 μL (0.125 μg) per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• Super Bright 436 can be excited with the violet laser line (405 nm) and emits at 436 nm
• We recommend using a 450/50 bandpass filter, or equivalent
• Please make sure that your instrument is capable of detecting this fluorochrome
• When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product No
• SB-4401) to minimize any non-specific polymer interactions
• Please refer to the datasheet for Super Bright Staining Buffer for more information
• 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].
