Product Summary

The Quantikine® Human LIF Immunoassay is a 4.5 hours solid phase ELISA designed to measure human LIF in cell culture supernates, serum, and plasma. It contains HEK293-expressed recombinant human LIF and antibodies raised against the recombinant protein. Results obtained for naturally occurring human LIF showed linear curves that were parallel to the standard curves obtained using the recombinant Quantikine® kit standards. These results indicate that this kit can be used to determine relative mass values for natural human LIF.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components

Recovery

The recovery of human LIF spiked to three different levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 103 92-112
EDTA Plasma (n=4) 90 83-96
Heparin Plasma (n=4) 90 83-99
Serum (n=4) 92 83-101

Linearity

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

Background: LIF

Based on its helical structure, LIF (Leukemia Inhibitory Factor) is considered a member of the Interleukin-6 family of cytokines. Functionally, it has been implicated in a many physiological processes including development, hematopoiesis, bone metabolism, and inflammation. Some cell types known to express LIF include activated T cells, monocytes, astrocytes, osteoblasts, keratinocytes, regenerating skeletal muscle, mast cells, and fibroblasts. The activities of LIF are mediated through a high-affinity heterodimeric receptor complex consisting of two membrane glycoproteins: an alpha subunit (LIF R alpha, also known as LIF R beta and CD118) that binds LIF with low affinity and the 130 kDa (gp130) subunit that does not bind LIF by itself, but is required for high-affinity binding of LIF by the complex.
