Identification of Differential Genes by Suppression Subtractive Hybridization: I. Preparation of Subtracted cDNA or Genomic DNA Library

Denis Rebrikov

Abstract

INTRODUCTIONSuppression subtractive hybridization (SSH) is one of the most powerful and popular methods for generating subtracted cDNA or genomic DNA libraries. This technique can be used to compare two mRNA populations and obtain cDNAs representing genes that are either overexpressed or exclusively expressed in one population as compared to another. It can also be used for comparison of genomic DNA populations. This protocol describes the preparation of a subtracted cDNA or genomic DNA library, and includes methods for cDNA synthesis, tester and driver DNA digestion, and adapter ligation.
