Description

Clostridium Perfringens, D is a highly purified, inactivated antigen derived from the Clostridium perfringens type D bacterium, a key causative agent of enterotoxemia in livestock. This product is essential for the development and quality control of diagnostic assays and vaccine formulations, ensuring accurate detection and effective immunization. It is a critical reagent for veterinary diagnostic laboratories, animal health research institutions, and pharmaceutical manufacturers focused on ruminant health and food safety.

Application

• Veterinary Diagnostic Kit Production: Primary antigen component for ELISA, latex agglutination, and other immunoassays to detect antibodies against C. perfringens epsilon toxin.
• Vaccine Development & QC: Used as a reference standard and immunogen in the research, formulation, and potency testing of clostridial vaccines for sheep, goats, and cattle.
• Research & Serological Studies: Vital tool for immunological research, epidemiological surveys, and studying the pathogenesis of enterotoxemia.
• Antitoxin Standardization: Serves as a challenge toxin or antigen for standardizing and calibrating antitoxin sera and therapeutic products.
• Quality Control in Manufacturing: Employed for in-process testing and final release of biological products to ensure batch-to-batch consistency and efficacy.
