VSTs have been produced primarily by ex-vivo cultures and by the expansion of T-lymphocytes after stimulation with viral antigens.
12.
If infected, their tissues will usually contain antibody that interferes with laboratory tests for either virus or viral antigen.
13.
Hawaii Biotech Inc ., chose Meridian's Viral Antigens Inc . plant in Memphis, Tennessee, to work on the project.
14.
Antibody responses against the viral antigen expression in the stroma can trigger a massive autoimmune response in the eye.
15.
In respiratory disease, diagnosis is confirmed by performing a direct fluorescent antibody test on nasal washes-which identifies the viral antigen.
16.
Other examples include tissue differentiation antigens, mutant protein antigens, oncogenic viral antigens, cancer-testis antigens and vascular or stromal specific antigens.
17.
Affected cells subsequently round up, become pyknotic, and disintegrate with release of virus and viral antigen ( Fig . 2B ).
18.
The first unequivocal evidence of viral replication is the appearance of nascent viral antigen in the nucleus ( Fig . 2A ).
19.
Viral antigen was detected in a muscle biopsy of a person suffering a recurrent episode of disease three months after initial onset.
20.
The other test detects viral antigen, which is a part of the virus that induces the body to produce antibodies against it.
