Im going to screen an expression library with antibodies, and I have
these two strains Y1089 and Y1090. Which would be a better host? Somebody
has managed to lose the MC9 plasmid from our 1090 strain, so I tried
Y1089 but it apparently only makes lysogens since there are no plaques.
the phages are there I checked it with LE392. So... is there a way of
making Y1089 to produce phage plaques, or should I get a new batch of Y1090?
