Abstract:
Selecting specific primers is crucial for polymerase chain reaction (PCR). Nonspecific primers will bind to unintended genes and result in nonspecific amplicons. MFEprimer is a program for checking the specificity of PCR primers against the background DNA. In this chapter, we introduce: (1) the factors that affect the specificity of primers; (2) the principle of MFEprimer and its settings; (3) how to use the MFEprimer to examine the specificity of primers.
