產品詳情

  • 產品描述：
    羊胰島素樣生長因子II(IGF2)酶聯免疫試劑盒（CSB-EL011088SH）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IGF2含量。IGF2（胰島素樣生長因子2）是一種重要的促有絲分裂細胞因子，與IGF受體結合，調節多種組織生長。其研究機制涉及IGF2蛋白的分泌、轉運和信號傳導，對細胞增殖、遷移、分化和存活等過程起關鍵作用。IGF2的異常表達與多種生長障礙和腫瘤相關。試劑盒檢測范圍為15.6 ng/mL-1000 ng/mL，適用于農業科學、動物模型研究等領域，可助力探索IGF2在綿羊生長發育、營養代謝調控中的作用機制，或作為評估特定條件下生物體內IGF2動態變化的有效工具。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 insulin-like growth factors possess growth-promoting activity. Major fetal growth hormone in mammals. Plays a key role in regulating fetoplacental development. IGF2 is influenced by placental lactogen. Also involved in tissue differentiation. In adults, involved in glucose metabolism in adipose tissue, skeletal muscle and liver. Acts as a ligand for integrin which is required for IGF2 signaling. Positively regulates myogenic transcription factor MYOD1 function by facilitating the recruitment of transcriptional coactivators, thereby controlling muscle terminal differentiation. Inhibits myoblast differentiation and modulates metabolism via increasing the mitochondrial respiration rate.; Preptin undergoes glucose-mediated co-secretion with insulin, and acts as physiological amplifier of glucose-mediated insulin secretion. Exhibits osteogenic properties by increasing osteoblast mitogenic activity through phosphoactivation of MAPK1 and MAPK3.

    1. The mRNA expression levels of MSTN, IGF-1 and IGF-2 were significantly different in the same skeletal muscle under different dietary intake. PMID: 25078581
    2. Data show that both short- and long-term exposure to high-altitude conditions decreased luteal growth and IGF-I and IGF-II gene expression but increased HIF-1 alpha and VEGF immunoexpression. PMID: 23521851
    3. In PR fetal sheep, IGF-2, IGF-1R and IGF-2R mRNA expression was increased in the heart compared to controls. PMID: 21807611
    4. weight loss in both normal and overweight mothers during the periconceptional period results in epigenetic modification of IGF2 in the adrenal gland, adrenal overgrowth, and increased vulnerability to stress in offspring PMID: 20371620
