產品詳情

  • 產品描述：
    人肌鈣蛋白I，骨骼肌快肌(TNNI2)酶聯免疫試劑盒（CSB-EL024012HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿,組織勻漿樣本中的TNNI2含量。TNNI2 即心肌肌鈣蛋白 I2，它作為心肌收縮調節的關鍵蛋白，與心肌功能緊密相關。在研究機制上，其異常表達或突變會影響心肌收縮舒張功能，在心肌疾病發生發展中起重要作用，是心血管疾病研究的潛在靶點。試劑盒檢測范圍為6.25 pg/mL-400 pg/mL，適用于肌肉發育、運動損傷模型、肌病機制等基礎研究領域。科研人員可通過定量分析不同生理或病理狀態下骨骼肌損傷標志物TNNI2的動態變化，為探索肌肉再生機制或藥物干預效果提供數據支持。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。

  • 功能：
    Troponin I is the inhibitory subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.

    1. Mutations in genes encoding cardiac troponin I (TNNI3) and cardiac troponin T (TNNT2) caused altered troponin protein stoichiometry in patients with dilated cardiomyopathy. TNNI3p.98trunc resulted in haploinsufficiency, increased Ca(2+) -sensitivity and reduced length-dependent activation. TNNT2p.K217del caused increased passive tension. PMID: 28436080
    2. TNNI2 gene missense mutation is associated with distal arthrogryposis type 1. PMID: 26374086
    3. report the first TNNI2 mutation in classical FSS and describe an atypical adult FSS case with only facial contractures resulting from somatic mosaicism PMID: 23850728
    4. Molecular genetic investigations revealed pathogenic mutations in MYH3, TPM2, and TNNI2 in one sporadic and 19 familial cases of distal arthrogryposis. PMID: 22519952
    5. Atrial re-expression of ssTnI during paroxysmal atrial fibrillation in patients does not seem to be part of the process of AF-associated cardiomyocyte dedifferentiation but seems to result from transient cardiomyocyte stress at the onset of AF. PMID: 15289369
    6. study found a novel TNNI2 mutation in a Chinese family with distal arthrogryposis type 2B PMID: 16802141
    7. Implantation of stable human clone expressing fast-twitch skeletal muscle troponin I in female BALB/c nude mice inhibits primary tumor growth and suggests that grafts are self-inhibitory by halting angiogenesis. PMID: 17393089
    8. These findings reveal a new function for TNNI2 as a co-activator of ERRalpha. PMID: 18331830
    9. Data found that fTnI normally associated with fast twitch skeletal muscle were present at significant levels in the thoracic aorta, and that fTnI transcripts were expressed in the smooth muscle layer of mouse blood vessels of all sizes. PMID: 18548613
    10. Gene expression revealed up-regulation of pro-angiogenic (PGF), anti-apoptotics (BAG-1, BCL-2), heart development (TNNT2, TNNC1) and extracellular matrix remodelling (MMP-2, MMP-7) genes in SM. PMID: 18805052
