Abstract: A surgical instrument caddy includes an elongated, generally rectangular main body having a support rod secured to one end and a plurality of hollow channels disposed therein. Each of the channels includes a first end terminating at the top surface of the main body, and a second end terminating at the bottom surface of the main body.

Abstract: The present invention relates to methods and compositons for isolation of nucleic acids from cells. In particular aspects, this invention relates to the use of chaotropic compositions, such as guanidine hydrochloride or guanidinium isothiocyanate, in combination with polyanionic compositions, such as those containing sulfated polysaccharides (i.e., heparin or heparitin sulfate), for the isolation of nucleic acids (RNA or DNA). This method involves disrupting and lysing cells using a nucleic acid releasing composition containing a chaotropic component for the release of nucleic acids from the cell (guanidine hydrochloride or guanidinium isothiocyanate). The released nucleic acids are collected by ethanol precipitation and resuspended before exposure to a polyanion-containing protein dissociating composition which promotes the dissociation of nucleic acid associated proteins from the resuspended nucleic acids.
