Rat CA19-9 (CarbohydRate antigen19-9) ELISA Kit (RTFI01489)

CA19-9 (sialyl Lewis A antigen) is a well-characterized tumor-associated carbohydrate marker most relevant to studies of pancreatic adenocarcinoma, cholangiocarcinoma, and gastrointestinal carcinogenesis. In rat experimental models, the analyte is quantified to monitor chemically induced or xenograft tumor progression, evaluate biliary pathology, and track biomarker dynamics across longitudinal study designs.

This Assay Genie kit is supplied as a complete microplate-based immunoassay, with pre-coated wells, lyophilized standards, biotinylated detection antibody, streptavidin-HRP conjugate, substrate, and wash buffer packed together. The procedure relies on a small serum or plasma sample volume added per well, sequential incubation and washing, and a quantitative readout on a compatible microplate reader. The capture antibody is rat-specific, with no significant cross-reactivity observed with homologous interfering analogues. Store kit components refrigerated; protect from light, aliquot reconstituted standards, and limit repeated freeze-thaw cycles of prepared working reagents.
