產品詳情

  • 產品描述：
    大鼠類固醇5α還原酶1 (SRD5A1)酶聯免疫試劑盒（CSB-E14053r）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織培養上清液、組織勻漿樣本中的SRD5A1含量。SRD5A1即5α-還原酶1型，在多種組織中表達。它能將睪酮轉化為活性更強的雙氫睪酮。對其研究機制主要圍繞調節雄激素活性展開，在前列腺疾病、脫發等病癥的發生發展中扮演角色，為相關治療藥物研發提供了重要靶點。試劑盒檢測范圍為15.6 pg/mL-1000 pg/mL，適用于實驗室研究中對SRD5A1表達水平的動態監測，如內分泌代謝研究、藥物干預實驗或疾病模型構建中酶活性變化的定量分析。為探索SRD5A1在生理及病理過程中的作用提供可靠工具。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。

  • 功能：
    Converts testosterone into 5-alpha-dihydrotestosterone and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology.

    1. Ziram inhibited SRD5A1 and AKR1C14 activities, thus possibly interfering with neurosteroid production in rats. PMID: 28707553
    2. Exposure of middle-aged rats to environmental enrichment increased mRNA levels of 5al;pha-reductase-1, 3alpha-HSD and cytochrome P450 17alpha-hydroxylase/c17,20-lyase and decreased the methylation state of the 5alpha-reductase-1 gene PMID: 26021641
    3. Low Srd5a1 expression is associated with benign prostatic hypertrophy. PMID: 23405234
    4. Changes in the expression of steroid 5-alpha reductase isoenzymes in the prostate in response to environmental stress. PMID: 23122426
    5. Tesosterone concentrations during postnatal sexual differentiation of the rat central nervous system, among other sex-dependent factors, influence brain levels of 5alpha-Reductase isozymes in adulthood PMID: 22131296
    6. Elevated levels of 5alpha-reduced androgens seen in hyperinsulinemic conditions might be explained on the basis of a stimulatory effect of insulin on 5alpha-reductase in granulosa cells. PMID: 20810561
    7. Thus, the present results indicate that the vitamin E-induced regulation of SRD5A1 and GCLM in rat liver is not directly mediated by changes in promoter DNA methylation. PMID: 20447326
    8. 5 alpha-R1 immunostaining was detected mainly in the white matter (Wm). PMID: 15305365
    9. great sexual dimorphism in the central nervous system (CNS) with respect to both 5alpha-reductase isozymes, and suggest a crucial role of dihydrotestosterone in the sexual dimorphism of the CNS in the female PMID: 16595696
    10. Our results demonstrate that both 5alpha-R isozymes are significantly higher in prefrontal cortex of male rats after acute swim stress in comparison with control rats PMID: 17826869
    11. Our results suggest that 5AR inhibitors elicit antipsychotic-like effects in animals and may be proposed as a putative novel target in the management of psychotic disorders. PMID: 18354385
