Western blot analysis of human ITAC was performed by loading 0.25 µg of recombinant human ITAC and induced HeLa cell culture supernatant onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with 5% Milk/TBST for at least 1 hour. Membranes were probed with an anti -human ITAC monoclonal antibody (Product # MA1032:clone 10C6, MA1033: clone 22F1 ) at a dilution of 1:1000 overnight at 4°C on a rocking platform. Membranes were washed in TBS-0.1%Tween 20 and probed with a goat anti-mouse-HRP secondary antibody (Product # 31430) at a dilution of 1:10,000 for at least one hour. Membranes were washed and chemiluminescent detection performed using Pierce Super Signal West Dura (Product #34075).

MA1032 has successfully been paired as the coating antibody in a sandwich ELISA with detection antibody MA1033B (biotinylated conjugate of clone 22F1).
Typical dilutions for sandwich ELISA include 1 µg/ml for coating and 0.125-0.25 µg/ml for detection.
The Molecular weight is ~8303 Da from positions 22 - 94 as determined by MALDI.
Interferon-inducible T-cell alpha chemoattractant ( I-TAC), belonging to the CXC chemokine family, is expressed in peripheral blood leukocytes, pancreas and liver, thymus, spleen, lung, small intestine, placenta and prostate. Its molecular weight is 8–11 kD. I-TAC is also known as CXCL-11 and IP-9. The cytokine is involved in regulating calcium release and inducing a chemotactic response in activated T-cells and is the dominant ligand for CXC receptor-3. The gene encoding this protein contains 4 exons and at least three polyadenylation signals which might reflect cell-specific regulation of expression. IFN-gamma is a potent inducer of transcription of this gene. It is upregulated in patients with AIDS, dementia and in patients with multiple sclerosis.
