Description
REA623 recognizes the human CD4 antigen, a 55 kDa single-pass type I membrane protein, also known as T4/Leu-3. CD4 is highly expressed on T helper cells and at a lower level on monocytes and dendritic cells. It is involved in the recognition of MHC class ll/peptide complexes by the TCR heterodimers and is the receptor for the human immunodeficiency virus (HIV). Additional information: Clone REA623 displays negligible binding to Fc receptors.
