摘要:I have been using an alternative to wedge gels that saves acrylamide, cuts gel drying time to 20 min and gives as good or better band squashing at the bottom of the gel. It was published in BioTechniq[阅读全文:]
摘要:For every 4 mls of culture, dissolve the BAC DNA pellet in 40 µl of water. for example: Usually each BAC is grown in 20 mls LB/CM total, then is dispensed into one Autogen tube (4 mls in each of[阅读全文:]
摘要:A simple, reversible way to a stop restriction reaction is by adding EDTA, which chelates Mg2+ , thereby preventing catalysis. If further manipulations of the digested DNA are to be performed, the res[阅读全文:]
