Human GALNT9 ELISA Kit (HUFI04176)

The Human GALNT9 ELISA Kit from Assay Genie quantitatively measures polypeptide N-acetylgalactosaminyltransferase 9, a Golgi-resident glycosyltransferase that initiates mucin-type O-linked glycosylation of substrate proteins. Investigators in glycobiology and oncology biomarker research rely on this colorimetric sandwich immunoassay to determine GALNT9 concentrations in human serum and plasma. The microplate format supports 96 assays per plate, with wells pre-coated with a polyclonal capture antibody specific for human GALNT9. A recombinant standard is included to generate a calibration curve, and the chromogenic readout yields absorbance values proportional to bound analyte. Typical sample volume is 100 uL per well, and serial dilutions of the standard bring the working range to encompass physiologically relevant concentrations. Researchers deploy the kit for in vitro biomarker profiling, pathway studies, and comparative cohort analyses where GALNT9 expression correlates with disease state. Components should be stored at 2-8°C to preserve reagent activity through the kit's shelf life; allow all reagents to equilibrate to room temperature before plate loading. The assay is validated for research use only and is not intended for diagnostic procedures.
