- the first base is designed using a mixed base corresponding to guanine (G) or adenine (A).

Therefore, in the case of genotyping by RFMP method, when amplifying a gene region in which a large number of mutations of a target gene exist, a mass spectrometry peak is produced by mixing a plurality of primers in a 1: 1 correspondence for each genotype. Are more difficult to analyze and are more likely to cause analysis errors.
