Molecular Weight of Sindbis Virus Ribonucleic Acid as Measured by Polyacrylamide Gel Electrophoresis

AUTOR(ES)
RESUMO

The molecular weight (MW) of Sindbis virion ribonucleic acid (RNA) determined by gel electrophoresis was in a range of 3.89 × 106 to 4.45 × 106 daltons. Upon denaturation with urea, it separated into fragments having an MW of 1.76 × 106 daltons. Viral-specific Sindbis 26S RNA contained a major species having an MW of 1.76 × 106 daltons.
