EasyWaytoCloneGenesFromaPhageLibrary
Easy Way to Clone The protocol is oriented towards a C. albicans genomic library I made in Lambda Zap II on 7/97.The overall sequence of events is: • Titer and plate out phage • Lift plaques onto filters and prepare them for screening • Make a probe • Hybridize the probe to the filters • Wash the filters and expose to film • Purify putative plaques • Excise plasmid from the des......阅读全文

转染，so－easy!－再也不用担心！
转染可谓是做生物学实验的大家经常会考虑的一项实验技术，大致原理也都是明白的。实验室的师妹也一直在进行这个实验，最近她却一直愁眉苦脸，问了才知道，原来她转染完的细胞，去跑qpcr验证的结果一直不行，转染效率太低以至于无法进行后续的实验。到底转染是什么呢，为什么转染效率不高呢，今天我们就来一起讨论一
