產品詳情

  • 產品描述:
    人促卵泡素(FSH)酶聯免疫試劑盒(CSB-E06867h)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FSH含量。促卵泡激素(FSH)是一種由垂體前葉分泌的糖蛋白激素,對性腺功能至關重要。它通過作用于性腺(卵巢和睪丸)的特定細胞,調節卵泡生長、雌激素產生、排卵和精子生成。FSH的活性形式是糖基化的異源二聚體,由α和β兩條多肽組成,其作用機理涉及與靶細胞表面的G蛋白偶聯受體結合,引發細胞內信號傳導,從而調控相關生理過程。試劑盒檢測范圍為2 mIU/ml-50 mIU/ml.,靈敏度為1 mIU/ml.。適用于實驗室開展生殖健康機制研究、生育力評估模型構建或激素相關疾病機理探索等科研項目;廣泛用于基礎醫學、動物科學等領域中FSH表達水平的定量分析,為生殖系統功能調控研究提供可靠工具。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。

Q:

I am curious about the specificity of this kit. Are the antibodies only specific to FSH Beta?

A:
Thanks for your inquiry. Yes the antibodies are only specific to FSH Beta. Beta is the specific subunit of FSH.

靶點詳情

  • 功能:
    Together with the alpha chain CGA constitutes follitropin, the follicle-stimulating hormone, and provides its biological specificity to the hormone heterodimer. Binds FSHR, a G protein-coupled receptor, on target cells to activate downstream signaling pathways. Follitropin is involved in follicle development and spermatogenesis in reproductive organs.

    16. Data suggest that low serum FSH levels in men with an SNP in promoter region of FSHB (-211G/T) result from reduced binding of LHX3 (LIM homeobox 3) to FSHB promoter/response element and down-regulation of FSHB transcription in gonadotrophs. PMID: 23766128
