Title of Invention: Assembled viral particles and t heir use in a vaccine to rotaviral disease (8247 words)
VP7 is the major outer shell glycoprotein with an approximate molecular mass of 38 kD in its unreduced form (as determined by SDS-PAGE) and 42 kD in its reduced form (as determined by SDS-PAGE).
VP7 is composed of approximately 325 amino acids and the nucleotide sequence and deduced amino acid sequence of VP7 from strain C486 (bovine) is shown in FIG.
VP7 and VP4 protein concentrations in growth media and infected cell lysates were estimated on SDS-PGE gels stained with Coomassie Blue, and western blots probed with VP7 and VP4 specific antisera.
