PCR products amplified by each primer set. (A) cDNA samples prepared from total RNA of each mammary gland were amplified. (B) Genomic DNA from each mammary gland was amplified. (C) Splicing variants of the cDNA from total RNA of the mammary gland and testis were amplified. Primer sets for each lane are shown in Table 1. The "M" indicates the molecular size marker (1-kbp DNA ladder; New England Biolabs). Arrowhead and "*" indicate novel BRCA2 transcript and non-specific PCR products, respectively.
