    • The inventions relates to compositions and method for determining the absolute counts of cells per unit volume of a sample. Such a method comprises: (a) providing a container containing: (i) a predetermined quantity of microparticles; and (ii) a cell-binding agent; in which the microparticles are disposed in or on a matrix which adheres to at least one wall of the container such that substantially all the microparticles are thereby attached to the container; (b) adding a known volume of sample to the container; (c) determining the ratio of microparticles to cells by counting microparticles and cells in a volume of the sample; and (d) determining the absolute count of cells by multiplying the number of cells per microparticle by the concentration of microparticles in the sample. Preferably, the matrix retains substantially all the microparticles in or on the container during routine handling, including inversion, of the container, in the absence of mechanical retaining means such as a retainer grid in the container.
    • 本发明涉及用于确定样品每单位体积的细胞的绝对计数的组合物和方法。 这种方法包括:(a)提供容器,其包含:(i)预定量的微粒; 和(ii)细胞结合剂; 其中微粒设置在基质中或基体上,该基质附着在容器的至少一个壁上,使得基本上所有的微粒从而附着到容器上; (b)向容器中加入已知体积的样品; (c)通过计数样品体积中的微粒和细胞来确定微粒与细胞的比例; 和(d)通过将每个微粒的细胞数乘以样品中微粒的浓度来确定细胞的绝对计数。 优选地,在没有诸如容器中的保持架网格的机械保持装置的情况下,基体在基本上将容器内的所有微粒保持在容器的常规处理(包括反转)中。
