Immunogen 2 N-terminal domains of human CD4 fused to human IgG1 Fc
Clone MEM-241
Isotype IgG1
Specificity The antibody MEM-241 recognizes CD4 antigen, a 55 kDa transmebrane glycoprotein expressed on a subset of T lymphocytes (,helper, T-cells) and also on monocytes, tissue macrophages and granulocytes.HCDM (former HLDA VIII) Meeting, May 2006, Qu °bec, Canada, WS Code M241
Characteristics The purified antibody is conjugated with tandem dye PE-DyLight™, 594 (PE-DL594) under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use.
Alternative Name CD4
Background CD4 (T4) is a single chain transmembrane glycoprotein and belongs to immunoglobulin supergene family. In extracellular region there are 4 immunoglobulin-like domains (1 Ig-like V-type and 3 Ig-like C2-type). Transmembrane region forms 25 AA, cytoplasmic tail consists of 38 aa. Domains 1,2 and 4 are stabilized by disulfide bonds. The intracellular domain of CD4 is associated with p56Lck, a Src-like protein tyrosine kinase. It was described that CD4 segregates into specific detergent-resistant T-cell membrane microdomains.Extracellular ligands: MHC class II molecules (binds to CDR2-like region in CD4 domain 1), HIV envelope protein gp120 (binds to CDR2-like region in CD4 domain 1), IL-16 (binds to CD4 domain 3), Human seminal plasma glycoprotein gp17 (binds to CD4 domain 1), L-selectinIntracellular ligands: p56LckCD4 is a co-receptor involved in immune response (co-receptor activity in binding to MHC class II molecules) and HIV infection (human immunodeficiency virus, CD4 is primary receptor for HIV-1 surface glycoprotein gp120). CD4 regulates T-cell activation, T/B-cell adhesion, T-cell diferentiation, T-cell selection and signal transduction.Defects in antigen presentation (MHC class II) cause dysfunction of CD4+ T-cells and their almost complete absence in patients blood, tissue and organs (SCID immunodeficiency).
Research Area Immunology, Adaptive Immunity, Hematopoietic Progenitors, CD Antigens, Surface Receptors of Immune Cells
Application Notes The reagent is designed for Flow Cytometry analysis of human blood cells using 4 µL reagent / 100 µL of whole blood or 10^6 cells in a suspension. The content of a vial (0.4 mL) is sufficient for 100 tests.

Working concentrations should be determined by the investigator.
Restrictions For Research Use only
Reconstitution No reconstitution is necessary.
Buffer The reagent is provided in phosphate buffered saline (PBS) containing 15 mM sodium azide and 0.2 % (w/v) high-grade protease free Bovine Serum Albumin (BSA) as a stabilizing agent.
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice Do not freeze.
Avoid prolonged exposure to light.
Storage 4 °C
Storage Comment Store in the dark at 2-8 °C. Do not use after expiration date stamped on vial label. Short-term exposure to room temperature should not affect the quality of the reagent. However, if reagent is stored under any conditions other than those specified, the conditions must be verified by the user.
