Product Specific Information

This antibody has been used for Flow Cytometry to detect HEK293T.17 cells transfected with vaccine-expressing membrane-bound SARS-CoV-2 spike protein. View Article

The immunogen is 100% (16/16) homologous to SARS-COV-2 (COVID-19) Spike protein. The cross reactivity is not empirically tested.

Suggested positive control: transfected mouse melanoma cell lysate.

Target Information

It has recently been shown that SARS (severe acute respiratory syndrome) is caused by a human coronavirus. Human coronaviruses are the major cause of upper respiratory tract illness, such as the common cold, in humans. Coronaviruses are positive-stranded RNA viruses, featuring the largest viral RNA genomes known to date (27-31 kb). The first step in coronavirus infection is binding of the viral spike protein, a 139-kDa protein, to certain receptors on host cells. The spike protein is the main surface antigen of the coronavirus. The glycosylated spike protein (as well as the nucleocapsid protein) can be detected in infected cell culture supernatants with antisera from SARS patients.

SARS-CoV-2 spike N-terminal domain modulates TMPRSS2-dependent viral entry and fusogenicity.

Cell reports

Meng B,Datir R,Choi J,Bradley JR,Smith KGC,Lee JH,Gupta RK

PA1-41165 was used in Flow cytometry/Cell sorting to conclude that the NTD allosterically modulates S1/S2 cleavage and spike-mediated functions in a spike context-dependent manner, and allosteric interactions may be lost when combining regions from more distantly related VOCs.
