Anti-Procalcitonin (PCT-katacalcin) Antibody

This monoclonal primary antibody from Antibodies.com targets the katacalcin region of procalcitonin, a 116-amino-acid calcitonin precursor widely investigated as a clinical biomarker for bacterial sepsis and systemic inflammation. Raised in mouse and purified by Protein A chromatography, the unconjugated IgG1 reagent is supplied as a 1 mg vial suitable for western blot, immunohistochemistry, and ELISA development workflows.

Investigators studying medullary thyroid carcinoma, where C-cells ectopically elevate circulating procalcitonin, and groups validating sepsis diagnostics in critically ill patient cohorts routinely employ anti-PCT antibodies to map antigen distribution and quantify analyte release. For long-term stability, aliquot the antibody upon arrival and store frozen at -20°C, protecting the solution from light and avoiding repeated freeze-thaw cycles, with short-term working stocks kept refrigerated. The unconjugated format allows flexible labeling for custom assay platforms, and the product is intended for research use only.
