The names of primer combinations are abbreviations and their corresponding full name are listed in Table 1.
The band pattern that absent for Hpa II but present for Msp I was regarded as full-methylation and the numbers of this kind of band pattern amplified by each primer pairs were scored in each material.
The band pattern that for present Hpa II but absent for Msp I was regarded as hemi-methylation and the numbers of this kind of band pattern amplified by each primer pairs were scored in each material.
