Abstract
The molecular weight of
Tipula
iridescent virus, based on sedimentation and diffusion coefficients, was 5.51 × 10
8
, with hydration of 0.57 g of water per g of virus. Deoxyribonucleic acid content, based on total inorganic phosphorus liberated, was 19 ± 0.2%. At 260 mμ, the virus gave an uncorrected absorbance of 18.2 cm
2
/mg of virus and a light-scattering corrected absorbance of 9.8 cm
2
/mg of virus. Amino acid analyses of the virus protein revealed a remarkable similarity to
Sericesthis
iridescent virus. The possibility is discussed that the four iridescent insect viruses reported to date bear a strain relationship.
