Description

Rhoptry-Associated Antigen-2, Plasmodium is a specific protein antigen derived from the malaria-causing *Plasmodium* parasite, with the CAS registry number 145184-78-7. This compound is of critical importance for research and diagnostic applications focused on malaria immunology and vaccine development. It is primarily needed by biotechnology firms, academic research institutions, and diagnostic kit manufacturers engaged in the fight against malaria.

Application

• Malaria Diagnostic Assay Development: Used as a key antigen in the development and validation of immunoassays (ELISA, lateral flow tests) for detecting *Plasmodium* infections.
• Vaccine Research & Development: Serves as a critical target antigen in preclinical studies for evaluating vaccine candidates aimed at eliciting protective immune responses.
• Immunological Studies: Employed in basic research to study host-parasite interactions, antibody responses, and the role of rhoptry proteins in malaria pathogenesis.
• Reference Standard: Acts as a purified reference standard for quality control and calibration in diagnostic manufacturing and research laboratories.
• Antibody Production: Utilized as an immunogen for generating monoclonal or polyclonal antibodies specific to *Plasmodium* rhoptry antigens.
• Serological Surveillance: Applied in epidemiological studies to assess past exposure and seroprevalence of malaria in population studies.

Quality Control

Our Rhoptry-Associated Antigen-2, Plasmodium is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high biological activity. Each lot is characterized for identity, purity, and specificity using advanced analytical techniques. A comprehensive Certificate of Analysis (COA) detailing purity, endotoxin levels, and functional assay data is provided with every shipment to support your research and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a dry environment before opening to prevent condensation and moisture uptake. For short-term use, aliquoting is recommended to avoid repeated freeze-thaw cycles.
