vector for constructing genomic libraries

vector permitting positive selection for inserts

Phage with inserts have the Spi- phenotype.

A lambda replacement vector for construction and screening of genomic libraries.

The left arm is 20 kb, the stuffer is 14 kb, and the right arm is 9 kb. lambdaEMBL3 (ATCC 37266) and lambdaEMBL4 (ATCC 37267) differ only in the orientation of the MCS surrounding the stuffer fragment.
