Abstract
We describe the construction of two complete sets of small insert, complete digest DNA libraries for each of the 24 human chromosomal types by the National Laboratory Gene Library Project. Flow sorting was used to purify the chromosomes which provided the DNA for cloning. One set of libraries was cloned into the HindIII site of the lambda vector Charon 21A, and the other set was cloned into the EcoRI site of the same vector. Characterization information from both in-house experiments and user feedback is presented. These chromosome-specific libraries are available to the general scientific community from a repository at the American Type Culture Collection, Rockville, MD. The second phase of the project, the construction of large insert, partial digest libraries in both lambda and cosmid vectors, is underway.
