Isolation of Bacteriophages T2 and T4 Attached to the Outer Membrane of Escherichia coli

Abstract

Phage T2 or T4 was adsorbed to Escherichia coli , and the outer (L) membrane was then isolated with the phage still attached in their usual postinjection appearance. T2 was readily inactivated by isolated cell walls but very poorly by purified L membrane. T4 was inactivated by neither.
