Abstract: An umbrella mounting system for PURPOSE includes a cart that may be urged along a support surface. The cart has a plurality of horizontal members. An umbrella is provided that has a shaft and a canopy. A mounting unit is removably coupled to the cart. The mounting unit insertably receives the shaft such that the canopy is positioned over the cart. Thus, the umbrella shades an area around the cart.

Abstract: The method is used for separating nucleic acids and other similar constructs. It involves selective introduction, enhancement, or stabilization of affinity handles such as single-strandedness in the undesired (or desired) nucleic acids as compared to the usual structure (e.g., double-strandedness) of the desired (or undesired) nucleic acids. The undesired (or desired) nucleic acids are separated from the desired (or undesired) nucleic acids due to capture by methods including but not limited to immobilized metal affinity chromatography, immobilized single-stranded DNA binding (SSB) protein, and immobilized oligonucleotides.
