SARS-CoV-2 (2019-nCoV) Inhibitor Screening ELISA Kit

COVID-19 Inhibitor Research [ FOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC OR THERAPEUTIC PROCEDURES. ] Temporarily not available outside of China.

Intended Use

The kit applies for the screening of SARS-CoV-2 (2019-nCoV) inhibitors.

Principle of the assay

The principle of the kit is competitive ELISA. The SARS-CoV-2 (2019-nCoV) Inhibitor in the samples competes with ACE2-His (Cat: 10108-H08B) to combine with immobilized SARS-CoV-2 S Protein RBD. The signal color becomes lighter as the content of SARS-CoV-2 Inhibitor increases.
