TA Cloning

Introduction of TA Cloning

TA cloning is a simple and convenient method of subcloning polymerase chain reaction (PCR) products. "TA" is short for "thymine" and "adenine."This cloning technique takes advantage of the terminal transferase activity of some DNA polymerases such as Taq polymerase, these enzymes preferentially add a 3'-end A-overhang to PCR products. This allows the direct insertion of such PCR products into the prelinearized cloning vector, which has a overhang on each 3'-end. This eliminates the need for restriction enzyme digestion of the vector or insert, primers with built-in restriction sites, or specially designed adapters, resulting in a much more efficient and robust cloning procedure.This technique is especially useful when compatible restriction sites are not available for the subcloning of DNA fragments.
