Product Summary

The Quantikine® QuicKit™ Human CXCL10/IP-10 Immunoassay is a one step, 80-minute solid phase ELISA designed to measure human IP-10 levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human IP-10 and antibodies raised against the recombinant protein. Results obtained using natural human IP-10 showed linear curves that were parallel to the standard curves obtained using the QuicKit™ standards. These results indicate that this kit can be used to determine relative mass values for natural human IP-10.

Precision

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

Scientific Data

Human IP-10 ELISA Standard Curve

Human IP-10 QuicKit Spiked Recovery Competitor Comparison IP-10 is spiked at three known concentrations throughout the range of the assay and run to measure response of the spiked sample matrix. Plasma recovery is 95% compared to 49% for the top competitor. In spike and recovery experiments, natural samples are spiked with the recombinant target analyte of interest to identify interference caused by sample matrices.

Human IP-10 QuicKit Spiked Linearity Competitor Comparison IP-10 is spiked at high concentration in various matrices and diluted with appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay. The linearity is between 99%-124% compared to 112%-183% for the top competitor.

Preparation and Storage

Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.

Background: CXCL10/IP-10/CRG-2

IP-10 was originally identified as an IFN-gamma-inducible gene in monocytes, fibroblasts and endothelial cells. The mouse homolog of human IP-10, CRG-2, shares approximately 67% amino acid sequence identity with human IP-10. The amino acid sequence of IP-10 identified the protein as a member of the CXC chemokine subfamily.

Entrez Gene IDs:
3627 (Human); 15945 (Mouse)
Alternate Names:
C7; chemokine (C-X-C motif) ligand 10; CRG2; CRG-2; CXCL10; gIP-10; IFI10; INP10; IP-10; mob-1; SCYB10

Assay Procedure

These assays utilize an anti-tag coated microplate. Standards, samples, and controls are added to plate, followed by subsequent addition of an antibody cocktail. Following a 1 hour incubation, plates are washed and substrate is added and incubated for 20 minutes. Stop solution is then added and plates are read using a standard microplate reader.
