||SRM NIST-2373 consists of genomic DNA extracted from five breast cancer cell lines with different amounts of amplification of the HER2 gene. The five purified genomic DNAs were solubilized in a buffer consisting of 10 mmol/L tris(hydroxymethyl)aminomethane and 0.1 mmol/L ethylenediaminetetraacetic acid disodium salt (EDTA) pH 8.0 (TE–4). The five components are genomic DNA materials derived from human cell lines SK-BR-3, MDA-MB-231, MDA-MB-361, MDA-MB-453, and BT-474, labeled A, B, C, D, and E, respectively. A unit of SRM 2373 consists of five vials, one of each component, containing approximately 100 μL of DNA solution. Each of these vials is labeled and is sealed with a color-coded screw cap.
