    • Methods, particles and kits for determining kinase activity within a sample are provided. An embodiment of a method includes exposing a fluorescent particle to an assay, wherein the fluorescent particle includes a support substrate having one or more fluorescent materials and a peptide substrate coupled to the support substrate via a functional group of the support substrate. The method further includes phosphorylating the peptide substrate during exposure of the fluorescent particle to the assay and processing the fluorescent particle such that the peptide substrate is dephosphorylated and a polarized double bond is generated at a dephosphorylated site. In addition, the method includes coupling a fluorescent reporter having a nucleophilic terminal group to the fluorescent particle via the polarized double bond.
    • 提供了用于确定样品中激酶活性的方法,颗粒和试剂盒。 一种方法的实施方案包括将荧光颗粒暴露于测定中,其中荧光颗粒包括具有一种或多种荧光材料的支撑衬底和通过支撑衬底的官能团与支撑衬底耦合的肽底物。 该方法还包括在将荧光颗粒暴露于测定期间磷酸化底物,并处理荧光颗粒,使得肽底物脱磷酸化,并在去磷酸化位点产生偏振双键。 此外,该方法包括通过偏振双键将具有亲核末端基团的荧光报告物偶联到荧光颗粒上。

    • Methods for characterizing immune diseases are provided which include exposing a sample of biological fluid from a patient to a pooled population of particles, wherein a first subset of particles is bound to a reactant that binds an antibody and a second subset of particles is bound to a reactant that binds an antigen. The methods further include determining a ratio of measured amounts of the antibody and the antigen in the sample. In some cases, the ratio is compared to one or more standard ratios representing differing states of the disease to determine a state of the disease within the patient. In other embodiments, the steps of exposing and determining a ratio of antibody to antigen are repeated for one or more additional samples of biological fluid taken from the patient. In such cases, at least two ratios are compared to analyze a progression of the disease.
    • 提供了表征免疫疾病的方法,其包括将患者的生物流体样品暴露于汇集的颗粒群体,其中颗粒的第一子集与结合抗体的反应物结合,并且第二子粒子与 结合抗原的反应物。 所述方法还包括确定样品中抗体和抗原的测量量的比例。 在一些情况下,将该比率与表示疾病状态不同的一个或多个标准比例进行比较,以确定患者内疾病的状态。 在其它实施方案中,对从患者取得的生物流体的一个或多个另外的样本重复暴露和确定抗体与抗原的比例的步骤。 在这种情况下,比较至少两个比率来分析疾病的进展。
