Detects mouse CCL1/I‑309/TCA‑3 in ELISAs and Western blots. In sandwich immunoassays, no cross-reactivity or interference with recombinant human CCL1, recombinant mouse (rm) CCL17, rmCCL19 or rmCCL24 is observed.
Monoclonal Rat IgG2B Clone # 148107
Protein A or G purified from hybridoma culture supernatant
Recombinant Mouse CCL1/TCA-3 Protein (Catalog # 845-TC)
Measured by its ability to neutralize CCL1/I‑309/TCA‑3-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CCR8. The Neutralization Dose (ND50) is typically 0.6-3.0 µg/mL in the presence of 10 ng/mL Recombinant Mouse CCL1/I‑309/TCA‑3.
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 CCL1/I-309/TCA‑3 and Neutralization by Mouse CCL1/I-309/TCA‑3 Antibody. Recombinant Mouse CCL1/TCA‑3 (Catalog # 845‑TC) chemoattracts the BaF3 mouse pro‑B cell line transfected with mouse CCR8 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Mouse CCL1/TCA‑3 (10 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse CCL1/I-309/ TCA‑3 Monoclonal Antibody (Catalog # MAB8451). The ND50 is typically 0.6‑3.0 µg/mL.

Mouse TCA‑3 is a member of the CC beta family of chemokines, designated CCL1. The human chemokine I-309, which shares approximately 42% amino acid (aa) sequence identity, is the orthologue of mouse TCA‑3. Mouse TCA‑3 and human I-309 also share significant sequence homology in the 5' flanking region of their genes and each contain an extra pair of cysteine residues not found in most other chemokines.
TCA‑3 cDNA encodes a 92 aa precursor protein with a predicted 23 aa signal peptide that is cleaved to produce a 69 aa mature protein. The sequence of TCA‑3 contains one potential N-linked glycosylation site. Mouse TCA‑3 is found on the distal portion of mouse chromosome 11 in a cluster with MIP-1 alpha, MIP-1 beta and JE. TCA‑3 acts by binding to the seven transmembrane spanning G-protein-coupled receptor, CCR8. TCA‑3 has been shown to chemoattract T-cells.
