Quality Research Begins with Quality Leukopaks
For studies that require assay-to-assay consistency, leukopaks can provide up to 100x more cells from the same donor than PBMCs. At Precision for Medicine, leukopaks are custom collected to your specifications at FDA-registered facilities, ensuring optimal cell yield, viability, and quality.
