MAVEn™高通量16通道果蠅代謝監(jiān)測系統(tǒng)
果蠅作為經(jīng)濟(jì)實(shí)用的模式動(dòng)物,可用于中樞神經(jīng)系統(tǒng)紊亂、炎癥性病變、心血管疾病、癌癥以及糖尿病等治療研究,而這些疾病的發(fā)生從生理上來說都與生物個(gè)體長期的代謝功能異常密切相關(guān)。
MAVEn™高通量16通道果蠅代謝監(jiān)測系統(tǒng)是由世界的美國Sable Systems International動(dòng)物代謝測量公司生產(chǎn)的一款16通道、高分辨率及自動(dòng)化的果蠅代謝監(jiān)測儀器,可廣泛用于代謝紊亂造成的各種流行疾病治療的機(jī)理研究。
