Creative Biolabs has successfully developed SARS, MERS and other anti-viral antibodies in the past to assist scientific research. Facing the difficult COVID-19, Creative Biolabs actively invests in antibody development to assist researchers to better understand the characteristics of 2019-nCoV and drug development. Currently, Creative Biolabs is proud to offer an extensive line of research antibodies to support the study of SARS-CoV-2/COVID-19, several of which were validated using virus-infected cell lysates.

Human Protease Inhibitor Antibody Array (Membrane, 32 Targets) (Y0253) (AbAr-0253-YC)

Antibody array is a specific form of protein microarray. In this technology, capture antibodies spotted on membranes or glass slide bind to specific target proteins present in the sample. Captured proteins are visualized using chemiluminescent or Laser Scanner. The signal produced is proportional to the amount of analyte bound. The Human Protease Inhibitor Antibody Array can be used to simultaneously detect the relative changes of 32 protease inhibiting analytes in a single sample.

Protease inhibitors (PIs) are a class of antiviral drugs that are widely used to treat HIV/AIDS and hepatitis C. Protease inhibitors prevent viral replication by selectively binding to viral proteases (e.g. HIV-1 protease) and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles.
