    • Disclosed are processes to increase the relative abundance of a molecule that is present in a test sample at relatively low abundance. The process includes fractionating a sample and immunizing hosts with the fractions. The antibodies produced from the fractionated test sample are directed primarily to molecules that are in relatively high abundance in the test sample fractions. These antibodies are then contacted with the test sample or a test sample to immuno-deplete relatively high abundance molecules from the sample to form a first depleted sample. These steps can be repeated a reiterative process of immuno-subtraction to produce second and third depleted samples where the relative abundance of the “low abundance” molecule is increased.
    • 公开的是以相对低的丰度增加存在于测试样品中的分子的相对丰度的方法。 该方法包括对样品进行分级并用分数免疫宿主。 从分级测试样品产生的抗体主要针对测试样品部分中相对较高丰度的分子。 然后将这些抗体与测试样品或测试样品接触以从样品中免除耗尽相对高丰度的分子以形成第一个耗尽的样品。 这些步骤可以重复免疫减除的重复过程,以产生其中低丰度分子的相对丰度增加的第二和第三贫化样品。

    • A fluorescence detection system comprises a light source (22), dichroic mirror (32), excitation port (16), emission port (14), and a detector. The light source (22) is, for example, a pulsed ultraviolet LED, with a light emission that decays sufficiently rapidly to permit gated detection of fluorescence from a fluorescently-labelled species, at a time when it is distinguishable from autofluorescence. The detector is, for example, an electron multiplying CCD, with high gain on-chip amplification. A circuit (26) may be used to control a repeating cycle of (i) generation of a 20-200 microsecond UV. pulse; (ii) a gate delay of 1-5 microseconds; and (iii) a 10-800 microsecond detection period. This allows time-resolved-fluorescence-microscopy with real time or near real time operation.
    • 荧光检测系统包括光源(22),分色镜(32),激发端口(16),发射端口(14)和检测器。 光源(22)例如是脉冲紫外LED,具有足够快速衰减的光发射,以允许在与自发荧光区分时从荧光标记物质进行门控检测。 检测器是例如具有高增益片上放大的电子倍增CCD。 电路(26)可用于控制(i)产生20-200微秒UV的重复循环。 脉冲; (ii)1-5微秒的门延迟; 和(iii)10-800微秒的检测周期。 这允许实时或接近实时操作的时间分辨荧光显微镜。
