Used in research and diagnostic applications to detect the SARS-CoV-2 spike protein receptor-binding domain (RBD). This antibody binds specifically to the RBD, making it valuable for immunoassays such as ELISA, lateral flow tests, and Western blotting. It supports the development of diagnostic kits for COVID-19 by enabling accurate identification of viral antigens. Also employed in neutralization studies to evaluate the efficacy of vaccines and therapeutic antibodies by assessing their ability to block spike protein interaction with host cell receptors. Suitable for use in biosensor platforms and flow cytometry where high specificity to the spike RBD is required.
