  • 產(chǎn)品描述：
    大鼠3氧代5α類固醇4脫氫酶2(SRD5A2)酶聯(lián)免疫試劑盒（CSB-EL022654RA）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、細胞裂解物樣本中的SRD5A2含量。SRD5A2 即 II 型 5α-還原酶，它能將睪酮轉(zhuǎn)化為二氫睪酮。該靶點與良性前列腺增生、雄激素性脫發(fā)等疾病密切相關(guān)。研究機制主要聚焦在研發(fā)其抑制劑，以減少二氫睪酮生成，改善相關(guān)病癥，相關(guān)藥物已在臨床應(yīng)用。試劑盒檢測范圍為6 pg/mL-1200 pg/mL，適用于探索大鼠模型中SRD5A2的表達水平與雄激素相關(guān)生理病理過程的關(guān)聯(lián)性，例如生殖內(nèi)分泌機制研究、前列腺組織代謝分析或藥物干預(yù)對類固醇合成途徑的影響評估等本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

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

    1. Results suggest that in the acute phase after spinal cord injury, the increased expression of 18kDa translocator protein and 5alpha-reductase may represent a protective endogenous response against tissue injury. PMID: 27150077
    2. findings show that, in the adult brain, 5alphaR2 is distributed in critical regions for behavioral regulation, suggesting that the functional role of this isoform is present throughout the entire lifespan of the individual PMID: 22776423
