  • 產品描述:
        人透明質酸 (Hyaluronic Acid, HA) 酶聯免疫試劑盒 (貨號: CSB-E04805h)采用雙抗體夾心法 ELISA 技術,專為定量檢測人血清、血漿、腦脊液(CSF)及組織勻漿樣本中的透明質酸 (HA) 含量而設計。
     
    1、生物學背景與研究價值:
        
    透明質酸 (HA) 是一種廣泛分布于人體結締組織、上皮組織、神經組織及關節滑液中的高分子糖胺聚糖,是細胞外基質的關鍵組分。
     
    (1)生理功能:HA 具有極強的持水能力,能維持組織形態、潤滑關節、調節細胞遷移與增殖,并在組織修復和炎癥反應中發揮核心作用。
    (2)臨床應用與科研方向:
        神經系統疾病: 檢測腦脊液(CSF)中的 HA 水平,輔助研究多發性硬化癥、腦損傷及神經退行性疾病中的血腦屏障通透性與基質重塑。
        組織再生與修復: 評估 HA 在傷口愈合、皮膚年輕化及軟骨修復過程中的動態變化。
        炎癥與纖維化: 監測血清或組織中 HA 濃度,作為肝纖維化、肺纖維化及慢性炎癥疾病的生物標志物。
        腫瘤研究: 探究腫瘤微環境中 HA 的異常高表達對癌細胞侵襲、轉移及耐藥性的影響。
     
    2、技術參數:
        檢測方法: 雙抗體夾心法 ELISA
        檢測范圍: 0.156 ng/mL - 10 ng/mL
        適用樣本: 血清、血漿、腦脊液(CSF)、組織勻漿
        適用物種: 人 (Human)

    3、應用說明:
        本試劑盒適用于基礎醫學研究中 HA 代謝機制的探索、藥物干預效果的評價,以及結合細胞實驗或多組織類型樣本進行的動態監測。它為組織再生、炎癥調控及相關疾病機制的研究提供了高靈敏度的可靠工具。

  • 本試劑盒所含材料:
      • A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human HA antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
      • Two vials lyophilized standard --- Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
      • Biotin-labeled HA antibody(100 x concentrate) 1 x 120 μl ---Act as the detection antibody.
      • HRP-avidin (100 x concentrate) 1 x 120 μl --- Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
      • Biotin-antibody Diluent 1 x 15 ml ---Dilute the high concentration Biotin-antibody to an appropriate working solution.
      • HRP-avidin Diluent 1 x 15 ml ---Dilute the high concentration HRP-avidin solution to an appropriate solution.
      • Sample Diluent 1 x 50 ml---Dilute the sample to an appropriate concentration.
      • Wash Buffer (25 x concentrate) 1 x 20 ml --- Wash away unbound or free substances.
      • TMB Substrate 1 x 10 ml --- Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
      • Stop Solution 1 x 10 ml --- Stop the color reaction. The solution color immediately turns from blue to yellow.
      • Four Adhesive Strips (For 96 wells) --- Cover the microplate when incubation.

Q:

We are looking into the best method to distinguish HA manufactured by fermentation and nature human HA.

A:
Thanks for your inquiry.
CSB-E04805h Human Hyaluronic acid, HA ELISA Kit
This kit can detect nature HA in polymerized form. As for HA manufactured by fermentation, it usually exists in free form.
We think it can not be detected out by the kit.
