Product Summary

The Quantikine Human I-TAC Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human I-TAC in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human I-TAC and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human I-TAC showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human I-TAC.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

EDTA Plasma (n=5) 98 85-112
Heparin Plasma (n=5) 98 90-106
Serum (n=5) 106 93-117

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of I-TAC were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: CXCL11/I-TAC

Interferon-inducible T cell a chemoattractant (I-TAC), also known as SCYB9B, H174 and beta-R1, is a non-ELR motif-containing CXC chemokine. I-TAC shares 36% and 37% amino acid sequence homology with IP-10 and MIG, respectively. I-TAC is expressed at low levels in normal tissues, including thymus, spleen and pancreas.

Entrez Gene IDs:
6373 (Human); 56066 (Mouse)
Alternate Names:
beta-R1; b-R1; chemokine (C-X-C motif) ligand 11; CXCL11; H174; H174IP9; Interferon gamma-inducible protein 9; Interferon-inducible T-cell alpha chemoattractant; IP-9member 11; ITAC; I-TAC; I-TACMGC102770; SCYB9B; small inducible cytokine subfamily B (Cys-X-Cys), member 9B; Small-inducible cytokine B11

  3.   Add 100 µL of Assay Diluent to each well.
    4. 100 µL Standard, Control, or Sample
  4.   Add 100 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
  5.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
    6. 200 µL Conjugate
  6.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
  7.   Aspirate and wash 4 times.
    8. 200 µL Substrate Solution
  8.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.
    9. 50 µL Stop Solution
