Description

Lcrq Protein, Yersinia Pseudotuberculosis is a purified protein derived from the pathogenic bacterium *Yersinia pseudotuberculosis*, identified by CAS NO 147338-24-7. This protein is a critical reagent in immunological and microbiological research, particularly for studying bacterial virulence mechanisms and host-pathogen interactions. It is essential for researchers and developers in the fields of vaccine development, diagnostic assay production, and infectious disease research who require high-purity, well-characterized bacterial antigens.

Application

• Research & Development: Used as a key antigen in immunological research to study the pathogenesis of *Yersinia pseudotuberculosis* and related species.
• Diagnostic Assay Production: Serves as a coating antigen or standard in the development of ELISA, immunoblot, and other serological diagnostic tests.
• Vaccine Development: Employed as a candidate immunogen or challenge material in preclinical studies for vaccine research against yersiniosis.
• Antibody Production: Utilized for the immunization of animals to generate polyclonal or monoclonal antibodies specific to Lcrq protein.
• Biochemical Studies: Acts as a substrate or target in protein-protein interaction studies and enzymatic activity assays related to bacterial type III secretion systems.
• Quality Control & Reference Standard: Functions as a reference material for the quality control of other diagnostic or research reagents.

Quality Control

Our Lcrq Protein is produced and tested under stringent conditions to ensure high purity, identity, and biological activity. Each batch is characterized using advanced analytical techniques including SDS-PAGE, Western Blot, and endotoxin testing. A comprehensive Certificate of Analysis (COA) detailing purity, concentration, and functional data is provided with every shipment to guarantee consistency and reliability for your critical research applications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted protein aliquots should be stored at -70°C to -80°C. Avoid repeated freeze-thaw cycles. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use.
