Product specifications

Intended use

This ELISA PathRF kit is intended for the quantification of human IL-8 (CXCL8) 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.

Recommendation

Product details

Product	ELISA PathRF: Human IL-8
Application	ELISA
Analyte	IL-8 (CXCL8)
Reactivity	Human
Specificity	This kit is based on a matched pair of mAbs specific for human IL-8 (CXCL8).

Shipping and Storage

Shipping	Shipped at ambient temperature.
Storage	Store detection mAb, Streptavidin-HRP, buffers/solutions, and substrate at 4-8 °C upon receipt. The ELISA standard should be stored at -20 °C. Plates may be kept at room temperature.
Shelf life	At least 12 months from date of receipt.

Performance

Standard range	3.16-1000 pg/ml
Sensitivity	2 pg/ml The lowest concentration that can be detected, but not necessarily quantified with precision and accuracy. This was determined by adding 2 standard deviations to the mean OD of background wells.

Analyte information

IL-8 (CXCL8)

Analyte description	Interleukin 8 (IL-8) is a proinflammatory cytokine produced by different types of cells, including monocytes, macrophages, and endothelial cells. Inflammatory stimuli, such as LPS, strongly induce IL-8 production by monocytes.
Alternative names	Interleukin-8, IL-8, IL8, CXCL8, GCP-1, GCP1, LECT, LUCT, LYNAP, MDNCF, MONAP, NAF, NAP-1, NAP1, SCYB8
Cell type	T cell, Treg, Tfh, Monocyte/MΦ, mDC
Gene ID	3576
