Description

Yopq Protein, Yersinia is a purified protein derived from *Yersinia* species, identified by the CAS registry number 131383-92-1. This high-purity biological reagent is critical for research and diagnostic applications requiring specific antigenic or enzymatic activity. It is primarily utilized by biotechnology firms, academic research institutions, and in-vitro diagnostic (IVD) kit manufacturers for the development of assays, immunological studies, and as a reference standard.

Application

• Immunoassay Development: Serves as a key antigen or coating protein for ELISA (Enzyme-Linked Immunosorbent Assay) and other immunoassay platforms.
• Diagnostic Reagent Production: Used as a core component in the manufacture of diagnostic kits for the detection of *Yersinia*-related infections or specific antibodies.
• Biomedical Research: Essential for studying host-pathogen interactions, immune response mechanisms, and bacterial protein function in academic and pharmaceutical R&D.
• Antibody Production & Purification: Acts as an immunogen for generating specific polyclonal or monoclonal antibodies, or as a ligand for affinity chromatography.
• Quality Control & Standardization: Functions as a reference material or positive control in laboratory quality assurance and proficiency testing programs.
• Vaccine Research: Investigated as a potential subunit vaccine candidate or for epitope mapping in vaccine development studies.
