Construction and characterization of a porcine P1-derived artificial chromosome (PAC) library covering 3.2 genome equivalents and cytogenetical assignment of six type I and type II loci.

A porcine P1-derived artificial chromosome (PAC) library of a male German Landrace pig was constructed in pCYPAC2. In total 90,240 clones were generated and individually transferred into microtiter plates. An average insert size of 119.
