| CD4, a single chain transmembrane glycoprotein is found on a T cell subset (helper/inducer) representing 45% of peripheral blood lympocytes. It is also present on 80% of thymocytes and at a lower level on monocytes. It is involved in recognition of antigen presented along with MHC class II by APCs. It serves as receptor for HIV. Antibody to CD4 recognizes T-helper cells required for recognition of class II antigens. It reacts with 60% of peripheral blood E rosette-positive (E+) cells while showing negligible reactivity with E+ cells, monocytes, granulocytes, EBV-transformed B cell lines, and mouse splenocytes. | | | Catalog # | C2255 | | CD4-positive T-cells provide helper funciton in pokeweed mitogen driven B-cell differentiation. Moreover, anti-CD4 selectively blocks the autologus mixed lymphocyte reaction (AMLR) with minimal or no effect on the allogeneic MLR (allo-MLR). Blocking of the autoreactivity occurs when either autologus B-lymphocytes or macrophages are used as stimulators. Specificity closely approximates the binding spectrum of OKT4 and Leu-3 antibodies both of which also recognize 55 to 65% of human peripheral blood T-cells. | | Applications | Suitable for use in Flow Cytometry, Radioimmunoprecipitation, and Immunohistochemistry. Other applications have not been tested. | | Recommended Dilutions | Immunohistochemistry: 1:4000 (Acetone-fixed frozen sections. Does not stain paraffin embedded tissue sections). | | Optimal dilutions to be determined by the researcher. | | Storage and Stability | May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. | | CAS Number | n/a | | Clone Type | Monoclonal | | Isotype | IgG1 | | Clone No | 8.F.33 | | Host | Mouse | | Source | Human | | Concentration | ~1mg/ml | | Form | Supplied as a liquid in PBS, pH 7.5, 0.1% sodium azide. | | Purity | Purified by column chromatography. | | Immunogen | Normal human blood lymphocytes | | Specificity | Recognizes and is highly reactive with human CD4 antigen (MW 59kD). Partially blocks binding of monoclonals to Leu-3a. Antibodies do not cross-block with gp129 and do not inhibit HIV induced syncytium formation. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
