Product Summary

The Quantikine^® Human Axl Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Axl in cell culture supernates, cell lysates, cerebrospinal fluid, serum, plasma, saliva, and urine. It contains
NS0-expressed recombinant human Axl and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Axl showed linear curves that were parallel to the standard curves obtained using the Quantikine^® kit standards. These results indicate that this kit can be used to determine relative mass values for natural human Axl.

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

Cell Culture Supernates, Cell Lysates, Serum, EDTA Plasma, Heparin Plasma, Saliva, Urine, Cerebrospinal Fluid

	Intra-Assay Precision			Inter-Assay Precision
Sample	1	2	3	1	2	3
n	20	20	20	20	20	20
Mean (pg/mL)	249	565	1115	258	582	1131
Standard Deviation	4.21	10	18.6	11.3	19.4	42.4
CV%	1.7	1.8	1.7	4.4	3.3	3.7

Recovery

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

Sample Type	Average % Recovery	Range %
Cell Culture Media (n=4)	89	81-98
Cell Lysis Buffer (n=1)	90	88-93
Saliva (n=4)	94	82-101

Linearity

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

Background: Axl

Axl (Ufo, Ark), Dtk (Sky, Tyro3, Rse, Brt) and Mer (human and mouse orthologs of chicken c-Eyk) constitute the TAM receptor tyrosine kinase subfamily. This RTK subfamily is characterized by an extracellular domain that consists of two Ig-like motifs and two fibronectin type III motifs. These receptors bind the vitamin K-dependent protein Growth Arrest Specific Gene 6 (Gas6). Receptor activation leads to cell proliferation, migration, or the prevention of apoptosis. Cellular signaling through this family of RTKs is involved in hematopoiesis, embryonic development, tumorigenesis, and spermatogenesis.

Long Name:
