This ELISA kit provides quantitative measurement of CXCL10 (IP-10) in human samples, supporting research into interferon-γ-driven immune signaling and chemokine-mediated T cell recruitment. Because CXCL10 levels can shift dramatically between homeostatic and inflammatory states, the kit is designed to capture this dynamic range without requiring extensive sample manipulation.
Detection Range: The 15.6–1000 pg/mL range spans baseline circulating CXCL10 concentrations in healthy serum (~50–300 pg/mL) through the elevated levels seen in active viral infection, autoimmunity, or transplant rejection, often exceeding 500 pg/mL. Most serum and plasma samples can be assayed neat or with minimal dilution, while inflamed tissue homogenates may require titration.
Sensitivity: At 7.8 pg/ml., the kit detects CXCL10 in low-expression contexts such as early post-infection timepoints, immunosuppressed patient plasma, or unstimulated cell culture supernatants where concentrations fall well below normal circulating levels.
Sample Compatibility: Validation across serum, plasma, and tissue homogenates enables paired systemic-versus-local analyses — for example, correlating circulating CXCL10 with intratumoral or graft-site chemokine gradients within a single study.
Assay Efficiency: The 1–5 hour protocol and 50–100 µL sample volume accommodate longitudinal clinical cohort studies and small-volume pediatric or biopsy-derived specimens where repeated sampling is necessary.
This kit is well suited for studies of viral hepatitis immune monitoring, solid organ transplant rejection, and tumor immune microenvironment profiling.
