Screening large numbers of plaques containing particular proteins is accomplished by techniques that are analogous to those described for screening with radioactive DNA probes. However, in the basic protocol described here, the plaques are screened with antibodies specific to the desired proteins. An alternate protocol provides a method for increasing the amount of recombinant protein in each plaque by inducing expression from the lac promoter that directs its expression.
