Abstract:
Preparation of a random-sequence DNA pool is presented. The degree of randomization and the length of the random sequence are discussed, as is synthesis of the pool using a DNA synthesizer or via commercial synthesis companies. Purification of a single-stranded pool and conversion to a double-stranded pool are presented as step-by-step protocols. Support protocols describe determination of the complexity and skewing of the pool, and optimization of amplification conditions.
