OrgFrontier™ Plasma Membrane Isolation Kit


產品介紹: 質膜(Plasma membrane)是研究最多的細胞膜(cellular membranes)之一。原核生物(Prokaryotic organisms)和真核生物(eukaryotic organisms)具有質膜,總的來說,由於它們的半滲透性特徵(semi-permeable characteristics),它們與周圍環境相通的同時包裹並保護了細胞質和細胞器。質膜是選擇性滲透的脂質雙層(lipid bilayers):它們允許營養物質和其他代謝物運輸到細胞質中,並允許同時輸出細胞廢物。氧氣,二氧化碳和其他氣態或親脂性小分子在質膜上自由擴散;然而,離子,氨基酸和醣類遵循嚴格的被動和主動細胞運輸機制。質膜脂質雙層主要由四種磷脂組成:磷脂膽鹼(phosphatidylcholine),磷脂乙醇胺(phosphatidylethanolamine),磷脂氨酸(phosphatidylserine)和鞘磷脂(sphingomyelin)。磷脂肌醇,第五種磷脂,也位於膜的內側。另外,許多蛋白質被嵌入或發現粘附在質膜的兩側。例如,通常發現糖蛋白附著在膜的外側。 BioVision的OrgFrontier™血漿膜分離試劑盒提供了一套專有的試劑和緩衝液,旨在優化從哺乳動物組織和細胞中提取和分離完整的質膜。需要執行超速離心機,並且可以在幾個小時內完成。

產品問與答
我們建議使用擺動鏟斗轉子(swinging bucket rotor)。但是,我們還測試了定角轉子(Timan 45或Ti 50,Beckman Coulter),它也可以正常工作。
