Product Summary

Simple Plex assay for the detection of human IFN-alpha (multisubtype) in cell culture supernatant (CCS), serum, and plasma (EDTA/Heparin)

Precision

Intra-Assay Precision (Precision within an assay) Each control was tested 16 times in one assay

Inter-Assay Precision (Precision between assays) Replicates of each control were tested in multiple assays performed by at least three technicians using two lots of reagents

Cell Culture Supernates, Serum, EDTA Plasma, Heparin Plasma

	Intra-Assay Precision		Inter-Assay Precision

Background: IFN-alpha

Interferon-alpha (IFN-alpha), also known as leukocyte interferon, represents a group of related but distinct proteins that share over 95% amino acid sequence homology. They are members of the type I interferon family which share a common cell surface receptor composed of two subunits, a 100 kDa ligand-binding subunit (IFN-alpha R2) and a 125 kDa ligand binding and signal transduction subunit (IFN-alpha R1) that is involved both in ligand binding and signal transduction. IFN-alpha has both anti-viral and immunomodulatory activities on target cells.
