2-8 µg/mL 

Use in combination with:

Detection Reagent: Human CCL1/I‑309/TCA‑3 Biotinylated Antibody (Catalog # BAF272)

Standard: Recombinant Human CCL1/I-309 Protein (Catalog # 272-I)

Measured by its ability to neutralize CCL1/I‑309/TCA‑3-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR8. The Neutralization Dose (ND50) is typically 0.1-0.5 µg/mL in the presence of 0.02 µg/mL Recombinant Human 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 and Neutralization by Human CCL1/I‑309 Anti-body. Recombinant Human CCL1/I-309 (Catalog # 272-I) chemoattracts the BaF3 mouse pro-B cell line transfected with human 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 Human CCL1/I-309 (0.02 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CCL1/I-309 Monoclonal Antibody (Catalog # MAB272). The ND50 is typically 0.1-0.5 µg/mL.

Background: CCL1/I-309/TCA-3

Human CCL1 was initially identified by subtractive hybridization as a transcript that was present in a gamma /δ T cell line but not in EBV-transformed B cells. Human CCL1 has been assumed to be a homologue of the mouse TCA3. While the two proteins share only approximately 42% amino acid sequence identity, both chemokines contain an extra pair of cysteine residues not found in most other chemokines. Human CCL1 and mouse TCA3 also share significant sequence homology in the 5’ flanking region of their genes. CCL1 cDNA encodes a 96 amino acid precursor protein with a hydrophobic signal peptide that is cleaved to yield a 73 amino acid mature protein. The CCL1 sequence contains one potential N‑linked glycosylation site, and natural CCL1 secreted by activated T cells is a glycoprotein doublet of 15‑16 kDa. The amino acid sequence of CCL1 identified the protein as a member of the chemokine beta subfamily.

Human CCL1/I-309/TCA-3 Antibody
By Anonymous on 11/22/2017
Application: ELISA Sample Tested: Serum and Plasma Species: Human

MAB272 was used as the capture and BAF272 as the detection in a sandwich immunoassay. The immunoassay standard was 272-I. It worked very well. Most healthy human samples were not detectable.
