title: Transfer of surface polymerase reaction products to a secondary platform with conservation of spatial registration.
abstract: Here, we describe a method for directly transferring very small amounts of reaction products from one surface to another. The approach is illustrated using a T4 DNA polymerase reaction to extend primers hybridized to a surface-confined DNA template. Following the extension reaction, the resulting oligonucleotide is transferred to a product surface. The important results are that (1) the spatial registration of the product is preserved after transfer; (2) the same reactant surface can be used to generate and transfer multiple iterations of products; and (3) the reaction products are biologically active after transfer.
