Product specifications

Intended use

This ELISA PathRF kit is intended for the quantification of human IL-6 in serum and plasma containing rheumatoid factor (RF). For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

ELISA PathRF kits
ELISA PathRF kits are designed to eliminate potential interference from RF and heterophilic antibodies. The combination of a recombinant detection mAb and RF-block diluent prevents RF and heterophilic antibodies from cross-linking the assay antibodies, effectively reducing the risk of false-positive signal. RF and heterophilic antibodies can be found at high concentrations in serum and plasma from individuals with autoimmune diseases such as rheumatoid arthritis. The kit has been validated with RF-containing plasma.

Analyte description

Interleukin 6 (IL-6) is a pleiotropic cytokine produced by many different cell types and plays a role in a wide range of functions, such as immune responses, acute-phase reactions, and hematopoiesis. Among other things, it augments antibody production from activated B cells in vitro.
