RT-PCR analysis of tau isoforms expressed in pinniped brains. RT-PCR with primer pair 2, which covers exons 0–5, confirmed three types of pinniped MAPT mRNA isoforms (a) composed of exons 1–5 (upper band), exons 1, 2, 4, and 5 (middle band), and exons 1, 4, and 5 (lower band) (b). RT-PCR with primer pair 5, which covers exons 9–11, confirmed two types of pinniped MAPT mRNA isoforms (c) composed of exons 9–11 (upper band) and exons 9 and 11 (lower band) (d)
