Aconvenientmethodfortheisolationofcrudenuclearpellets.
This procedure describes a convenient method for the isolation of crude nuclear pellets from N. crassa. The method, an adaptation of the one developed by Hautala et al ((1977 J Bact 130:704-713) utilizes a Braun homogenizer to disrupt the cells. The main advantages of the technique are that the cells need not be froen, large amounts of material can be handled, the homogenization is fast and easily controlled, fe......阅读全文
