E. Elution of DNA fragments from agaroseDNA fragments are eluted from low-melting temperature agarose gels using an unpublished procedure first developed by Dr. Roe. Here, the band of interest is excised with a sterile razor blade, placed in a microcentrifuge tube, frozen at -70degC, and then melted. Then, TE-saturated phenol is added to the melted gel slice, and the mixture again is frozen and then thawed. After thi......閱讀全文
