Background

XCL1 (Lymphotactin, SCM-1 alpha, Chemokine (C motif) ligand 1) and XCL2 (SCM-1 beta, Chemokine (C motif) ligand 2) comprise the C chemokine family, lacking two of the four invariant cysteines normally found on chemokines (1,4). Their sequences differ by 2 amino acids and they are primarily expressed by CD8+ T cells and NK cells (1-5). XCL1 and XCL2 act as ligands for the chemokine receptor XCR1 (1-5). XCR1-positive dendritic cells cross-present antigens to naïve CD8+ T cells, priming them to become activated cytotoxic CD8+ T cells (6,7). In addition, in mouse models, the XCL1-XCR1 signaling axis was shown to be involved in the formation of self-tolerance through the development of Treg cells within the thymus (8).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
