Sandwich ELISA - Human CXCL9 ELISA Kit (AB219047)
Interpolated concentrations of native CXCL9 in PHA-M stimulated human PBMC cell extract based on a 200 μg/mL extract load and human thyroid tissue extract based on a 500 μg/mL extract load.
The concentrations of CXCL9 were measured in duplicate and interpolated from the MIG standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CXCL9 concentration was determined to be 993.9 pg/mL in PHA-M stimulated PBMC cell extract and 824.9 pg/mL in thyroid tissue extract.

Comparison of CXCL9 in unstimulated and PHA-M stimulated human PBMC cell supernatants.
Human PBMC cells were cultured in the absence or presence of 1.5% PHA-M for 2 days. The concentrations of CXCL9 were measured in three different dilutions of the supernatant samples in duplicates and interpolated from the MIG standard curve. The interpolated values are plotted (mean +/- SD, n=2). The mean MIG concentration was determined to be 20.4 pg/mL in PHA-M stimulated PBMC cell supernatant, 1.6 pg/mL in unstimulated supernatants and undetectable in media (not shown).

Sandwich ELISA - Human CXCL9 ELISA Kit (AB219047)
Interpolated concentrations of native CXCL9 in PHA-M stimulated and unstimulated human PBMC cell culture supernatant (2 days) samples.
The concentrations of CXCL9 were measured in duplicates, interpolated from the MIG standard curves and corrected for sample dilution. Undiluted samples are as follows : PHA-M stimulated PBMC supernatant 2.5% and unstimulated PBMC supernatant 100% (neat). The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean CXCL9 concentration was determined to be 20.4 ng/mL in neat PHA-M stimulated PBMC supernatant and 1.62 ng/mL in neat unstimulated PBMC supernatant.

Product details
Human CXCL9 ELISA Kit ab219047 is a rapid single-wash 90-min Sandwich ELISA to measure Human CXCL9 in cell culture extracts, cell culture supernatant, tissue extracts. This SimpleStep sensitivity is 5 pg/mL.
How the assay works
Human CXCL9 SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

CXCL9, is a small cytokine belonging to the CXC chemokine subfamily that lacks an ELR motif in front of the first cysteine. CXCL9, also known as MIG, (Monokine Induced by Gamma Interferon) is a T-cell chemoattractant, which is induced by Interferon Gamma. This subfamily also includes Interferon Gamma Induced Protein 10 (IP-10 or CXCL10) and Interferon Inducible T-cell Alpha Chemoattractant (I-TAC or CXCL11) whose genes are located near the gene for MIG on human chromosome 4. MIG, IP-10 and I-TAC all elicit their chemotactic functions by interacting with the G protein coupled chemokine receptor CXCR3 (GPR9 or CD183).

Biological function summary
This cytokine plays a pivotal role in the immune system by regulating leukocyte trafficking. CXCL9 exerts its function through binding to the CXCR3 receptor attracting T cells towards sites of inflammation or infection. This interaction is significant in mediating immune surveillance and host defense. CXCL9 does not form part of a larger protein complex but its chemokine activity is critical for immune system coordination. Scientific studies often highlight its involvement through CXCL9 function and expression analysis.
Pathways
CXCL9 significantly influences the chemokine signaling pathway and the Th1-type adaptive immune response. Within these pathways it interacts closely with other chemokines like CXCL10 and CXCL11 which also bind to the CXCR3 receptor. These pathways highlight the coordinated mobilization of T cells during immune challenges and inflammation emphasizing how CXCL9 is often examined alongside these related chemokines in research settings.
