The BD Vacutainer CPT Molecular Diagnostic Tube is an innovative solution for isolating mononuclear cells and plasma from whole blood. Its unique design utilizes a density gradient polymer gel and sodium citrate additive to gently separate mononuclear cells, resulting in a highly concentrated and accurate cell population. Ideal for molecular diagnostic tests, such as immunotyping, culture, and gene-amplification techniques (e.g., PCR), this tube offers one-step isolation, saving time and minimizing cell loss. Its versatile applications and compatibility with automated pipetting systems enhance laboratory efficiency. The sterile and disposable design ensures sample integrity, making it a reliable choice for streamlined molecular diagnostic workflows.
