  • 精密度：

    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.

  • 線性度：

    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.

靶點(diǎn)詳情

  • 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.
  • 基因功能參考文獻(xiàn)：
    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
  • 亞細(xì)胞定位：
    Secreted. Note=Released from the secretory granules upon mast cell activation.
  • 蛋白家族：
    Peptidase S1 family, Tryptase subfamily
