Purification and characterization of giant empty proheads from packaging-defective 23ptg mutants of bacteriophage T4.

Virology - 1 Oct 1993

Rao V B, Leffers G

Abstract excerpt

We constructed packaging-defective gene 23ptg mutants of bacteriophage T4 that produced giant proheads of varying lengths. The giant proheads constituted up to 20% of the total proheads. A purification protocol was developed to prepare large quantities of highly pure giant proheads. The purified...
