Cat. No. HS-452 011BT |
100 µg purified IgG, lyophilized, labeled with Biotin.
Biotin is a small vitamin B complex molecule. Its small size minimizes interference with antibody binding sites and allows for efficient conjugation without compromising antibody functionality. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |

The severe acute respiratory syndrome coronavirus type 2 (SARS-CoV2) is an enveloped positive-sense single stranded RNA virus that has been identified in the beginning of 2020 (1). It infects human host cells by docking via its spike protein (S) to the ACE2 surface receptor (2) and can cause mild to very severe and even deadly Covid-19 courses (3).
The very abundant Nucleocapsid or N-protein packages the viral RNA (4) and shares only little homology to other abundant members of the coronavirus family like NL63, 229E, HKU1 or OC43. This characteristic makes it a suitable target to discriminate between Covid-19 and other coronavirus infections.
