RESUMO
lad (lambda adsorption), an Escherichia coli mutant that loses the ability to adsorb lambda phage immediately after a shift to high temperature (e.g., 42 C), was isolated. This property for phage adsorption is irreversible and has been observed with phage lambda and 21 but not with phages 434, phi 170, and phi 80. A crude receptor preparation, extracted from lad cells will cholate-ethylenediaminetetraacetic acid by the procedure of Randall-Hazelbauer and Schwartz (1973), inactivated the phage lambda only at low temperature.
