Alexa Fluor® 488 Rat Anti-Mouse Ly-6C Antibody (S-R523)

Ly-6C is a glycosylphosphatidylinositol-anchored cell-surface protein belonging to the Ly-6/uPAR/α-neurotoxin superfamily, selectively expressed on murine monocyte and T-cell subsets where it serves as a dynamic lineage and activation marker—its high level on pro-inflammatory “classical” monocytes (CD11b⁺Ly-6C^hi) enables their recruitment via CCR2 to inflamed tissues, whereas Ly-6C^lo monocytes patrol vasculature and replenish resident macrophages, and transient up-regulation on CD8⁺ T cells correlates with effector differentiation; structurally it forms a three-finger α-helical bundle that can laterally associate with lipid rafts and signaling partners such as T-cell receptor or integrin complexes to modulate calcium flux, cytokine release, and adhesion, thereby critically steering innate–adaptive immune crosstalk in infections, autoimmunity, and cardiovascular disease.
