$Human HL60 Cells were fixed with 2% PFA (10min at room temperature) and then permeabilized with 0.1% PBS-Tween for 20 min at room temperature. The cells were then incubated in 1 X PBS \/ 2% BSA \/ 10% goat serum to block non-specific protein-protein interactions for 15 min at room temperature. Cells were stained with CD4 Polyclonal Antibody Unconjugated (bs-0647R; green) at 1:100 for 30 min at room temperature. The secondary antibody, Goat anti-rabbit IgG-FITC (bs-0295G-FITC), was used for 40 min at room temperature. Primary antibody staining is compared to unstained cells (dark blue), secondary only (light blue), and isotype control (bs-0295P; orange).$

Background	Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class II molecule:peptide complex. The antigens presented by class II peptides are derived from extracellular proteins while class I peptides are derived from cytosolic proteins. Interacts simultaneously with the T-cell receptor (TCR) and the MHC class II presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. LCK then initiates different intracellular signaling pathways by phosphorylating various substrates ultimately leading to lymphokine production, motility, adhesion and activation of T-helper cells. In other cells such as macrophages or NK cells, plays a role in differentiation/activation, cytokine expression and cell migration in a TCR/LCK-independent pathway. Participates in the development of T-helper cells in the thymus and triggers the differentiation of monocytes into functional mature macrophages.
