Virion proteins of 0305φ8-36 separated by SDS-PAGE. A Bio-Rad Tris-HCl gradient gel (8 to 16% polyacrylamide) was employed, and proteins were visualized by staining with Coomassie Brilliant Blue; lane 1, Precision Plus Protein Standard (Bio-Rad); lane 2, purified 0305φ8-36. The identities of the proteins in the eight most intense bands are indicated. The putative functions of these proteins are: gp125, major head protein; gp124, head decoration protein); gp139, tail sheath protein; gp140, tail tube protein; gp119, gp129 and gp131, candidates for curly fiber components; and gp81, unassigned.
