Grade: recombinant antigen is a virus-like particle (VLP) containing all the three structural rubella virus proteins, namely c-core protein and 2 surface glycoproteins E1 and E2 but lacking genomic viral RNA.

Source: recombinant antigen is produced by continuous cell line of an animal origin transfected by plasmid bearing the set of rubella virus structural protein genes.

Application: Coating/capture antigen for specific IgG/IgM antibody rubella virus detection in human sera

Purification: The recombinant cell culture is grown using alpha-MEM containing 10% FCS by roller cultivation. After reaching a continuous monolayer a tissue culture is harvested and clarified by a slow spped centrifugation at 1000 rpm for 30 minutes. VLP are pelleted by high- speed centrifugation and further purified by sucrose density 30-60% linear gradietn centrifugation at 25000 rpm for 2.5 hours. The VLP zone is collected, diluted ten times with PBS and pelleted by centrifugation at 21000 rpm for 1.5 hours.

Presentation: Solution in PBS, pH7.2 containing 0.1mM PMSF

Protein conc: 1mg/ml by modified Bradford method (Bio-Rad Protein Assay Kit II, cat> 500-0002)

Immunoreactivity: Tested in EIA and western blotting using anti-rubella Mab clone Ru6 (see cat#RDI-TRK3R23-Ru6) and anti- Rubella virus positive human sera.

Storage: -20'C
