硼酸鋰緩衝液 硼酸鋰緩衝液英語lithium borate bufferLB緩衝液英語LB buffer是用於瓊脂糖電泳的緩衝溶液常用於分離核酸如DNARNA由硼酸鋰氫氧化鋰一水合物和硼酸組成 已隱藏部分未翻譯内容歡迎參與翻譯 LBR is a registered USPTO trademark of Faster Better Media LLC which owns US patent  covering lowconductance lithium borate polynucleotide electrophoresis Lithium Borate buffer has a lower conductivity produces crisper resolution and can be run at higher speeds than can gels made from TBE or TAE  Vcm as compared to  Vcm At a given voltage the heat generation and thus the gel temperature is much lower than with TBETAE buffers therefore the voltage can be increased to speed up electrophoresis so that a gel run takes only a fraction of the usual time Downstream applications such as isolation of DNA from a gel slice or Southern blot analysis work as expected with lithium boric acid gels SB buffer containing sodium borate is similar to lithium borate and has nearly all of its advantages at a somewhat lower cost but the lithium buffer permits use of even higher voltages due to the lower conductivity of lithium ions as compared to sodium ions and has a better resolution for fragments above kb
