BD Biosciences has launched its NucleoSpin Extract II Kit. The product can be used both for gel extraction and PCR purification. BD said the spin column binds DNA to a silica membrane in the presence of chaotropic salt. Once the binding mixture is loaded onto the column, only a single wash step using an optimized buffer is required. Downstream applications include sequencing, ligation, labeling, cloning, and restriction enzyme digestion.
