The clone SK3, a mouse monoclonal antibody selectively binds with a 55-59kD type I transmembrane glycoprotein and a member of the immunoglobulin superfamily. CD4 contains four extracellular Ig-like domains (D1-D4). The epitope for SK3 is located within the D3 domain of the protein, which has a structure resembling an Ig variable domain. Expression of CD4 is observed in subsets of T lymphocytes, monocytes, macrophages, and dendritic cells. Through interaction of MHC-II, CD4 facilitates cell-cell interaction, thymic differentiation, and activation of downstream signaling cascades. HIV infection of T-cells is instigated through binding of HIV to CD4. Binding of SK3 antibody blocks HIV infection through CD4 and also blocks the mixed lymphocyte reaction (MLR).
mFluor™ fluorescent labeling dyes are developed specifically for flow cytometry applications to enable optimal multi-color detection. These dyes are excellent alternatives to the phycoprotein-based tandems that are quite difficult to couple to an antibody or other biomolecules and offer greater light stability and brighter fluorescence. The mFluor™ 450 fluorophore is a great alternative to these dyes: V450, Pacific Blue™, VioBlue?, eFluor? 450, Brilliant Violet 421 and Super Bright 436.
