Abstract

We report the construction of a series of derivatives of pUC18 in which a modified multiple cloning site is flanked by one or two BglII sites. The reading frame of the lacZ alpha fragment was retained in each construct, permitting the recognition of transformants containing plasmids with inserts by visual screening for loss of blue coloration.
