Oxytherm+多通道線粒體呼吸測定系統(tǒng)

先進的Clark氧電極系統(tǒng)——研究線粒體呼吸的科研利器

實時監(jiān)測反應體系中溶解氧的濃度及變化，可多通道（最大8通道）同時檢測多個樣品

• 研究線粒體的I態(tài)、II態(tài)、III態(tài)、IV態(tài)呼吸，計算呼吸控制率及P/O比等；

• 研究肌肉、肝臟、大腦器官組織等細胞、細菌、酵母、藻類等微生物的呼吸（耗氧）速率；

• 研究呼吸途徑（抗氰呼吸、細胞色素氧化酶途徑、糖酵解途徑等）；

• 研究有氧參與的酶促反應(生物反應）速率，有氧參與的化學反應；

• 研究某些化學合成物質的放氧速率。

系統(tǒng)特點

• 24位高分辨率10^-3pmol·ml^-1

• 電子精確控溫(精度±0.5℃）

• 多通道實時顯示數(shù)據(jù)（1～8通道可選）

• 樣品用量少0.2～2.5ml

• 能與H⁺電極同時測定
