CDC researchers have developed methods of producing unlimited quantities of Group-C (GpC) rotavirus antigens. GpC rotaviruses are a major, worldwide cause of acute gastroenteritis in children and adults that is distinct from Group-A rotavirus. However, GpC rotaviruses cannot be grown in culture, resulting in a lack of tools for detection and treatment of GpC rotavirus disease. Consequently, the true clinical burden of GpC rotavirus disease has not been clearly established.
This technology allows for the expression of the three major capsid proteins (VP2, VP6 and VP7) of GpC rotavirus by recombinant baculovirus and assembly of virus-like particles (2-6-7 and/or 6-7) within insect cells. Further, this CDC generated technology allows for the large-scale access to GpC rotavirus antigens, previously infeasible, and will permit use of these novel virus-like particles for the development of rotavirus diagnostic assays and improved vaccine formulations.

Immunoassay - ELISA
Immunoassays are quick and accurate tests to detect specific molecules. Immunoassays rely on an antibody to bind to the specific structure of a molecule. Antibodies are proteins generated by animals in response to the invasion of a foreign molecule (anti...
