Angiotensin II induces ovulation and oocyte maturation in rabbit ovaries via the AT2 receptor subtype.

abstract：:We have found that microwave (MW) stabilization greatly improves detection of the estrogen receptor (ER) in frozen sections of rhesus monkey oviduct by immunocytochemistry (ICC). Fresh samples of fimbriae were MW-irradiated, frozen, and then cryosectioned. The frozen sections were also MW-treated and then fixed in a p...
