MAVEn™高通量16通道果蠅代謝監(jiān)測系統(tǒng) 返回列表頁

果蠅作為經(jīng)濟實用的模式動物，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)生從上來說都與生物個體*的代謝功能異常密切相關。

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動物代謝測量公司生產的一款16通道、高分辨率及自動化的果蠅代謝監(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理研究。

MAVEn™果蠅代謝系統(tǒng)作為果蠅代謝分型監(jiān)測方面的產品，主要具備以下特點：

2. 15秒就可以完成一只果蠅的代謝監(jiān)測，這代表了目前技術的水平。

3. 數(shù)據(jù)可以通過SD卡把帶時間標簽的CSV格式直接導出到電腦。

4. 可選配FLIC果蠅覓食、AD-2果蠅活動、氣體（氧氣、二氧化碳、水汽以及其它可檢測氣體）等監(jiān)測單元。
