COVID-19 S-Protein (S1RBD) PharmaGenie ELISA Kit Kit (SBRS1711)

Used in SARS-CoV-2 spike protein research, this ELISA Kit from Assay Genie quantifies the receptor-binding domain (RBD) of the S1 subunit in cell culture supernatant and serum samples. Researchers apply the kit to monitor recombinant S1 RBD expression during vaccine development, characterize antibody responses in convalescent specimens, and screen inhibitor candidates that disrupt ACE2 receptor binding and viral entry. The assay uses a colorimetric read-out compatible with standard plate readers, and the microplate layout supports mid-throughput screening of experimental cohorts. Each kit contains pre-coated plates and reagents sufficient for 96 assays, with all components intended for research use only. The S1 RBD region is a primary target of neutralizing antibodies, making this kit a practical tool for serological studies and for evaluating immunogenicity of vaccine candidates that express this domain.
