Monkeypox virus A29L antigen
The Monkeypox virus A29L antigen is a surface protein associated with the monkeypox virus (Mpox), a zoonotic virus that can be transmitted from animals to humans and between individuals. Detection of the A29L antigen in a sample indicates an active infection, as antigens are typically present during the early symptomatic phase of the illness.
Description
It is a viral surface protein that plays a role in the monkeypox virus’s structure and is used as a biomarker to detect an active Mpox infection.
A positive result indicates that monkeypox virus proteins have been found in the sample, suggesting a current or recent infection.
Yes, since antigens are usually detectable shortly after symptom onset, A29L antigen testing can identify infection in the early, contagious phase.
Antigen testing detects the virus itself (current infection), whereas antibody tests detect the body’s immune response (past or ongoing infection).
