The vector was completely linearized, and homologous sequences of the end of the linearized vector of 15-25 bp were introduced into the 5 'end of the positive and reverse PCR primers of the inserted fragment, so that the 5' and 3 'ends of the PCR products of the inserted fragment had exactly the same sequence corresponding to the two ends of the linearized vector, respectively. Under the action of recombinant enzyme, the recombinant reaction of PCR product and linearized vector can be completed in as little as 5 min at 50℃.

The total volume of the column is 1.1 ml, so a 400 μl reservoir is available for qwashing and elution steps. The column features a screw cap, is polypropylene and has a 30 μm hydrophilic polyethylene frit above a snap off end. The columns can use 1,5 and 2 ml centrifge tubes as collection tubes. Frits are supplied but not installed in the column. Simply add the affinity resin and sample to one of the spin columns, then use a microcentrifuge to efficiently wash away contaminants and elute your purified sample without losing any resin in the process.
