Abstract
Standard Reference Material (SRM) 2365 is intended for use in the value assignment of BK virus deoxyribonucleic acid (DNA) to BK DNA controls and standards. A unit of SRM 2365 consists of a well characterized, linearized plasmid, containing BK virus DNA solubilized in 10 mmol/L 2-amino-2-(hydroxymethyl)-1,3 propanediol hydrochloride (Tris HCl) and 1 mmol/L ethylenediaminetetraacetic acid disodium salt (disodium EDTA) pH 8.0 buffer (TE), with 50 ng/μL yeast tRNA added to ensure stability. A unit of the SRM consists of one 0.5 mL tube containing approximately 110 μL of DNA solution. The tube is labeled and is sealed with a screw cap. This publication documents the production, analytical methods, and statistical evaluations involved in realizing this product.
