Autotaxin Activity Assay


Zoom
 
Catalog No.:  K-4100

Description:  Echelon's Autotaxin Activity Assay gives a quantitative measurement of autotaxin (ATX) activity in biological samples by measuring changes in fluorescence over time.

Sample Volume: 400 μL / sample (50 μL per well, 8 wells per sample)
Sample Number: 10 samples (in duplicate) / 96 well assay
Sample Type: Currently this kit has been tested for the quantification of autotaxin activity in serum, plasma, ovarian ascites, and cell culture media.

Product Background: The assay developed by Echelon Biosciences Inc. uses the fluorogenic autotaxin substrate FS-3. FS-3 is an LPC analogue that is conjugated with both a fluorophore and a quencher. In its native state the quencher interferes with the fluorophore’s fluorescence. Once autotaxin cleaves FS-3, the fluorophore becomes liberated from the quencher, resulting in increased fluorescence.
This assay gives a quantitative measurement of autotaxin activity in biological samples by measuring changes in fluorescence over time. Because the assay is not end point based, it has the advantage of being less susceptible to error arising from mistiming the addition of components to different sample wells. The final readout is in quantitative units that correct for inconsistencies between different users equipment.
