產(chǎn)品描述：

人類胰蛋白酶 β2(TPSB2)酶聯(lián)免疫試劑盒（CSB-EL024128HU）為雙抗夾心法ELISA試劑盒，定量檢測(cè)血清、血漿、組織勻漿樣本中的TPSB2含量。TPSB2（類胰蛋白酶2）是一種胰蛋白酶樣絲氨酸蛋白酶，屬于肽酶家族S1。它僅作為肝素穩(wěn)定的四聚體具有酶促活性，對(duì)所有已知的內(nèi)源性蛋白酶抑制劑具有抗性，并在哮喘和其他過(guò)敏性和炎癥性疾病發(fā)病機(jī)制中發(fā)揮作用。試劑盒檢測(cè)范圍為0.137 ng/ml- 100 ng/ml，支持科研領(lǐng)域?qū)PSB2的功能研究，例如炎癥性疾病模型的分子機(jī)制探索、藥物干預(yù)效果評(píng)估或細(xì)胞分泌功能分析，也可用于生物樣本中TPSB2表達(dá)水平的定量比較實(shí)驗(yàn)。適用于生命科學(xué)基礎(chǔ)研究及生物標(biāo)志物開(kāi)發(fā)等場(chǎng)景。本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見(jiàn)產(chǎn)品說(shuō)明書(shū)。

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
