ABSTRACT:
A bacterial preparation capable of packaging phage .lambda. DNA is disclosed. This preparation is in lyophilized form and is stable at ambient temperature. In a preferred form, the preparation contains an over-expressed terminase protein, is prepared from the bacterial strain E. coli Cla [.lambda. c/857 Sam7 .DELTA.(cos-Nu1-A)::Kn.sup.r ]/.lambda. pTER and is capable of a packaging efficiency of at least 1.times.10.sup.8 pfu/.mu.g wild type .lambda. DNA. The present invention is also a method of creating a phage .lambda. DNA packaging extract comprising the steps of preparing a bacterial extract capable of packaging phage .lambda. and lyophilizing said extract.
