產品詳情

  • 產品描述：
    人凝血因子XIIIB鏈(F13B)酶聯免疫試劑盒（CSB-EL007922HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、尿液、組織勻漿樣本中的F13B含量。F13B是凝血因子XIII的B亞基，參與凝血級聯反應的最后環節，與A亞基共同組成異四聚體。F13B缺乏催化活性，但能穩定A亞基并調節凝血酶激活轉谷氨酰胺酶，從而穩定纖維蛋白凝塊。F13B基因突變可導致遺傳性FXIII缺陷癥，表現為終身出血傾向、傷口愈合不良等。試劑盒檢測范圍為0.312 ng/mL-20 ng/mL，本試劑盒適用于生命科學領域研究，可用于探究F13B在血栓形成、遺傳性凝血缺陷或組織修復等生理病理過程中的動態變化，為心血管疾病模型構建、藥物干預效果評估及分子機制研究提供可靠工具。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    The B chain of factor XIII is not catalytically active, but is thought to stabilize the A subunits and regulate the rate of transglutaminase formation by thrombin.
  • 基因功能參考文獻：
    1. In VTE patients the changes of FXIII level and their effect on the risk of VTE show considerable sex-specific differences. Intron K polymorphism results in decreased FXIII levels, but does not influence the risk of VTE. PMID: 28865246
    2. The results suggest that plasma FXIII levels are subjected to multifactorial regulation with age, fibrinogen level and FXIII-B intron K polymorphism being the major determinants. Their effect on FXIII levels might influence the risk of thrombotic diseases. PMID: 27821352
    3. Genetic markers associated with low FXIIIB levels increase risk of ischemic stroke cardioembolic subtype. PMID: 26159793
    4. The FXIII-B intron K nt29756 G allele was associated with significant protection against CAS and MI in patients with a fibrinogen level in the upper tertile. PMID: 25569091
    5. Changes in plasma levels of FXIIIB are associated with cognitive decline in the elderly. PMID: 26088309
    6. Here, we update the knowledge about the pathophysiology of factor XIII deficiency and its therapeutic options. [review] PMID: 24503678
    7. Case Report: congenital FXIII-B deficiency in which alloantibodies developed to exogenous FXIII-B. PMID: 23407795
    8. FXIIIb subunit is found to be within normal range in eight Tunisian famillies with congenital factor XIII deficiency caused by two mutations, while expression of the FXIIIA subunit gene is decreased or undetectable. PMID: 19937244
    9. Develop ELISA/chemoluminescence assay demonstrating that FXIII-A and FXIII-B are low concentration components of tear proteome. PMID: 20079358
    10. role of FXIIIB in modifying catalytic activity of FXIIIA2 during factor XIII mediated crosslinking of fibrinogen PMID: 11816711
    11. F13 B subunit antigen may have a role in susceptibility to stroke based on this study of family members of patients in South Asia PMID: 15634282
    12. Genetic variants of factor XIIIb were evaluated on the effects of survival in myocardial infarction. PMID: 17515963
    13. at least 3 out of the 10 Sushi domains of FXIII-B have the distinct function of forming a homodimer and a heterotetramer, which should be ascribed to the differences in their amino acid sequences PMID: 18652485
    14. A specific colorimetric assay for measuring FXIIIB activity is reported. PMID: 19646949
