Description

Surface Protein 40, Plasmodium Falciparum is a recombinant protein antigen derived from the malaria-causing parasite Plasmodium falciparum. This protein is a critical reagent for research and diagnostic development aimed at combating malaria, a major global health challenge. It is primarily utilized by biotechnology firms, academic research institutions, and diagnostic manufacturers focused on immunology, vaccine development, and serological testing.

Application

• Immunoassay Development: As a key antigen for the development and calibration of ELISA and other immunoassays to detect anti-P. falciparum antibodies.
• Vaccine Research: Serves as a target antigen in preclinical studies for evaluating vaccine candidates and understanding protective immune responses.
• Antibody Production & Characterization: Used to immunize animals for generating polyclonal or monoclonal antibodies specific to P. falciparum surface proteins.
• Diagnostic Kit Manufacturing: Incorporated as a coated antigen in rapid diagnostic tests (RDTs) and other point-of-care diagnostic devices for malaria.
• Serological Studies: Employed in epidemiological research to assess exposure and immunity profiles in populations from endemic regions.
• Quality Control Reference: Acts as a reference standard for the quality control of other malaria-related biological reagents and assays.
