The claimed subject matter comprises a device to collect and preserve cells comprising of: (1) a collection container comprised of a tube having an open end and a closed end, a closure in the open end of the tube, a vacuum drawn to a predetermined level inside the container; and (2) compounds including an anticoagulant agent and a fixative agent, wherein the compounds are in a sufficient amount to preserve said cells' original morphology and antigenic sites without significant dilution of said cells, and thereby allowing said cells to be directly analyzed by a flow cytometer without further treatment. The claimed subject matter further comprises of a method of making a collection device for cells comprising of : (1) providing a tube having an open end and a closed end; (2) preloading compounds including: an anticoagulant agent, and a fixative agent into the tube, wherein the compounds are in a sufficient amount to preserve the cells' original morphology and antigenic sites without significant dilution of the cells, and thereby allowing the cells to be directly analyzed by a flow cytometer without further treatment; (3) inserting a closure into the open end of the tube; and (4) drawing a vacuum inside the tube to a predetermined level to form the collection device.
所述主题包括一种收集和保存细胞的装置,包括:(1)收集容器,由具有开口端和闭口端的管子、管子开口端的封口、容器内抽到预定水平的真空组成;以及(2)包括抗凝剂和固定剂的化合物,其中化合物的量足以保存所述细胞的原始形态和抗原位点,而不会显著稀释所述细胞,从而使所述细胞无需进一步处理即可直接用流式细胞仪分析。所述主题还包括一种细胞收集装置的制作方法,该方法包括:(1) 提供一个具有开口端和闭口端的管子;(2) 预装化合物,包括抗凝血剂、抗凝血剂、抗凝血剂、抗凝血剂、抗凝血剂、抗凝血剂、抗凝血剂、抗凝血剂和抗凝血剂:抗凝剂和固定剂,其中化合物的量足以保持细胞的原始形态和抗原位点,而不会显著稀释细胞,从而使细胞无需进一步处理即可直接用流式细胞仪分析;(3) 将封口插入管的开口端;(4) 将管内的真空度抽至预定水平,以形成收集装置。
