Enclosed are E. coli K-12 and its lambda-sensitive mutant, W-1485. I am very pleased that you should be interested in the
chemistry of lambda.
The only good way to get high titer lysates is by induction with UV (Lwoff effect). If you would care to come up some time
we'll be glad to give all the details. Esther and I have an ms. in GENETICS on the general biology of lambda--we'll
send reprints when available.
