  • 产品描述:
    人胰蛋白酶β-2(TPSB2)酶联免疫试剂盒(CSB-EL024128HU)为双抗夹心法ELISA试剂盒,定量检测血清、血浆、组织匀浆样本中的TPSB2含量。TPSB2(类胰蛋白酶2)是一种胰蛋白酶样丝氨酸蛋白酶,属于肽酶家族S1。它仅作为肝素稳定的四聚体具有酶促活性,对所有已知的内源性蛋白酶抑制剂具有抗性,并在哮喘和其他过敏性和炎症性疾病发病机制中发挥作用。试剂盒检测范围为0.137 ng/ml- 100 ng/ml,支持科研领域对TPSB2的功能研究,例如炎症性疾病模型的分子机制探索、药物干预效果评估或细胞分泌功能分析,也可用于生物样本中TPSB2表达水平的定量比较实验。适用于生命科学基础研究及生物标志物开发等场景。本品仅用于科研,不用于临床诊断,产品具体参数及操作步骤详见产品说明书。

    Intra-assay Precision (Precision within an assay): CV%<8%

    Three samples of known concentration were tested twenty times on one plate to assess.

    Inter-assay Precision (Precision between assays): CV%<10%

    Three samples of known concentration were tested in twenty assays to assess.

  • 线性度:

    To assess the linearity of the assay, samples were spiked with high concentrations of human TPSB2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • 功能:
    Tryptase is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type. May play a role in innate immunity.
  • 基因功能参考文献:
    1. These observations indicate that betaII-tryptase activity is post-translationally regulated by an allosteric disulfide bond. PMID: 24142694
    2. Results indicate a key role for heparin in the activation of human betaI- and beta2-tryptase. PMID: 15567416
    3. The disease severity and plasma tryptase levels were not affected by the number of alpha or beta tryptase alleles in mastocytosis patients. PMID: 17449330
    4. Strong linkage of TPSAB1 and TPSB2 and pairing of deficiency alleles with functional alleles in observed haplotypes protect human subjects from "knockout" genomes and indeed from inheritance of fewer than 2 active alleles. PMID: 19748655
  • 亚细胞定位:
    Secreted. Note=Released from the secretory granules upon mast cell activation.
  • 蛋白家族:
    Peptidase S1 family, Tryptase subfamily
