Product Summary for Mouse IFN-alpha All Subtype Quantikine ELISA Kit

The Quantikine™ Mouse IFN-alpha All Subtype immunoassay is a 3.5 hour solid-phase ELISA designed to measure IFN-alpha in mouse cell culture supernates, serum, and plasma. It contains HEK293-expressed recombinant mouse IFN-alpha and has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse IFN-alpha showed dose response curves that were parallel to the standard curves obtained using the Quantikine mouse kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse IFN-alpha.

Recovery for Mouse IFN-alpha All Subtype Quantikine ELISA Kit

The recovery of mouse IFN-alpha spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 98 91-106
EDTA Plasma (n=4) 105 91-121
Heparin Plasma (n=4) 106 96-120
Serum (n=4) 102 86-118

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of mouse IFN-alpha were serially diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.

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.
