    • In a procedure for quantitative optical analysis of fluorescently-labelled biological cells (5) a cell layer is appplied to a transparent carrier at the base (2) of a reaction vessel (1) so that it is in contact with the solution (3) containing the fluorescent dye (4). The sensitivity of the determination may be significantly improved by adding to the solution (3) a masking dye (9), which absorbs the exciting light (6) for the fluorescent dye (4) already present in the solution (3) and/or its emitted light (7), and/or by applying an interlayer (10) that is permeable to the solution but absorbs and/or reflects the exciting light (6) or the emitted light (7) to the cell layer at the base (2). The same procedure may be used to improve sensitivity in quantitative optical analysis of a luminescent biological cell layer. In the latter case the interlayer (10) should be composed so that is possesses a high reflection factor with respect to luminescent light (11). Analogously, these procedural principles may also be applied in receptor studies to mask disturbing background radiation in quantitative optical analysis of fluorescently- or luminescently-labelled participants in a reaction. In this case a receptor layer (12) is placed at the base (2) of a reaction vessel (1) in contact with a solution (supernatant 3) in which a fluorescent or luminescent ligand (13) has been dissolved. The sensitivity and accuracy of the determination may be significantly improved if a masking dye (9) which absorbs the exciting light (6) for the fluorescent dye and/or its emitted light or (in case of luminescent ligands) the luminescent light is added to the supernatant (3). An interlayer (10) that is permeable to the solution (3) but absorbs and/or reflects the exciting light (6) and/or the emitted light or the luminescent light may be applied to the cell or receptor layer (12) at the base (2) instead of the masking dye in the solution (3) or possibly as a supplementary measure.
    • 在用于荧光标记的生物细胞的定量光学分析的方法(5)是细胞的在透明支持体与(4)含有(3)相接触的荧光染料溶液的层在反应容器(1)的底部(2)。 分析检测的灵敏度可以如果在除了现有的荧光染料的溶液(3)(4)被加入到一个掩蔽染料(9),该激励光(6)的荧光染料(4)和/或它的发射光被显着地改善 (7)吸收及/或时,(6)或发射光(7)的吸收和/或反射的分离层(10)涂布在细胞层的底部(2)渗透到该溶液中的激发光。 也可以应用于本方法,以改善发光生物细胞层的定量光学分析的灵敏度。 剥离层(10)在此情况下,其具有用于发光的光(11)的高反射率是这样的。 以类似的方式,这些方法原理也可以应用到受体的研究以掩蔽干扰背景辐射在荧光或发光标记的反应物的定量光学分析。 在这种情况下,它是在一个反应​​容器(1)的底部(2)与在接触溶液(上清液3),其中,荧光或发光配位体(13)式求得的受体层(12)。 分析检测的灵敏度和准确度可能在这种情况下大大提高如果将上清液3是掩蔽染料(9)添加被这为荧光染料和/或它的发射光或激发光(6)吸收发光(在发光配位体的情况下) , 而不是在溶液(3),或者,如果必要的话,作为一种附加措施的细胞或受体层(12)在底部(2)渗透一种为溶液(3)中,激发光(6)和/或发射光的遮蔽染料的 或发光光吸收和/或反射的分离层(10)被应用。
