This kit includes 50 SK-2S buccal swabs and our Buccal-Prep Plus DNA Isolation Kit, sufficient for 50 reactions.
Isohelix buccal swabs have been specifically designed to offer increased yields of high quality buccal cell and genomic DNA.  Our swabs are suitable for both human and veterinary use and offer significant advantages compared to other DNA swab designs in terms of efficiency of cell collection by the unique swab matrix, which in conjunction with a quick release surface maximizes DNA yields.  Swab batches are ethylene oxide treated and routinely tested for human DNA contamination.
Each SK-2S buccal swab is packaged with a 2ml microtube and special cap. After the buccal sample is obtained, the swab is inserted in the microtube and the special cap is slid down the shaft and applied to the tube. When the shaft of the swab is pulled out, the swab itself disengages from the shaft and remains in the tube. The cap is then plugged with the attached plug for a secure seal and the tube with the swab inside can be transported. The DNA can subsequently be isolated in the 2ml tube, or the swab can be transferred to a different tube.
The Buccal-Prep Plus DNA Isolation Kit is a precipitation-based kit combining all the necessary optimized buffers to fully lyse and simply purify DNA from Buccal swabs. The kit has a fast protocol that produces high yields and purity for all downstream processing applications. As with our other precipitation-based chemistries, no solvents, alcohol, or other external buffers are required, giving fewer processing steps and creating a faster process time.
The BPP-50/SK2 kit is an updated version of the DDK-50/SK2 kit.
