Human XCL1/Lymphotactin Antibody Summary
Accession # P47992
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Chemotaxis Induced by XCL1/Lymphotactin and Neutralization by Human XCL1/Lymphotactin Antibody. Recombinant Human XCL1/ Lymphotactin (695-LT) chemoattracts the BaF3 mouse pro-B cell line transfected with human XCR1 in a dose dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (AR002). Chemotaxis elicited by Recombinant Human XCL1/ Lymphotactin (0.5 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human XCL1/ Lymphotactin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF695). The ND50 is typically 3.00-30.0 µg/mL.

Human lymphotactin (Lptn)/XCL1 (also named human SCM-1 alpha and ATAC) and its mouse homologue belong to the C or gamma subfamily of chemokines. The C chemokines lack two (the 1st and 3rd ) of the four invariant cysteine residues normally found in the CC and CXC chemokines and have an extended carboxy terminus. Human lymphotactin encodes a 114 amino acid residue precursor protein with a 21 amino acid residue predicted signal peptide. The expression of lymphotactin is abundant in some activated T cells such as activated CD8+ T cells and other class I MHC restricted T cells. Lptn expression is absent in CD4+ T cells. Human and mouse Lptn share approximately 60% amino acid sequence homology. The gene for lymphotactin has been mapped to chromosome 1 in both human and mouse. Recombinant human lymphotactin has been shown to have chemotactic activity for lymphocytes and NK cells. The orphan receptor GPR5 has been reported to be the specific receptor for Lptn.
