Human EXTL1 (Exostosin-like 1) ELISA KIT (HUFI05257)

For researchers investigating heparan sulfate biosynthesis and glycosaminoglycan metabolism, this 96-assay enzyme immunoassay kit from Assay Genie enables quantitative measurement of human exostosin-like 1 (EXTL1) in samples prepared from serum or plasma. EXTL1 functions as a glycosyltransferase that initiates the elongation of heparan sulfate chains on proteoglycans, and changes in its expression have been studied in tumor biology, developmental signaling, and certain cancer contexts. The assay uses an absorbance-based readout on a standard microplate reader, with the kit supplying pre-coated wells, recombinant protein standards, biotinylated detection antibody, streptavidin-HRP conjugate, and substrate solution for standard curve generation. Each kit contains materials for 96 individual determinations; reagents should be stored refrigerated and protected from light to maintain activity. Typical applications include profiling glycosaminoglycan pathway activity in tumor tissue, mapping expression changes during development, and characterizing signaling pathways that depend on heparan sulfate chain elongation. The assay is intended for research use only.
