Product Details
All in vitro aptamer selection experiments require the use of a "selection buffer". This buffer not only serve to maintain the pH of the solution, but also provide the necessary ionic strength and co-factors to allow unique DNA structures to form. In addition, the presence of divalent metal ions may act as co-factors to allow DNA to form more intricate and complex structures. Overall, these ions exist to give the DNA library an opportunity to access a diverse set of structural motifs that can be used for recognition of their intended target.
