人胰高血糖素樣肽1.7-36(GLP-1.7-36)酶聯免疫分析(ELISA)
試劑盒使用說明書
本試劑僅供研究使用 目的:本試劑盒用于測定人血清、血漿、組織勻漿及相關液體樣本中胰高血糖素樣肽1.7-36(GLP-1.7-36)的含量。
實驗原理:
本試劑盒應用雙抗體夾心法測定標本中人胰高血糖素樣肽1.7-36(GLP-1.7-36)水平。用純化的人胰高血糖素樣肽1.7-36(GLP-1.7-36)捕獲抗體包被微孔板,制成固相抗體,往包被的微孔中依次加入人胰高血糖素樣肽1.7-36(GLP-1.7-36),再與HRP標記的檢測抗體結合,形成抗體-抗原-酶標抗體復合物,經過*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉化成藍色,并在酸的作用下轉化成最終的黃色。顏色的深淺和樣品中的人胰高血糖素樣肽1.7-36(GLP-1.7-36)呈正相關。用酶標儀在450nm波長下測定吸光度(OD值),通過標準曲線計算樣品中人胰高血糖素樣肽1.7-36(GLP-1.7-36)含量。

樣本處理及要求:
1. 血清:室溫血液自然凝固10-20分鐘,離心20分鐘左右(2000-3000轉/分)。仔細收集上清,保存過程中如出現沉淀,應再次離心。
2. 血漿:應根據標本的要求選擇EDTA或檸檬酸鈉作為抗凝劑,混合10-20分鐘后,離心20分鐘左右(2000-3000轉/分)。仔細收集上清,保存過程中如有沉淀形成,應該再次離心。
3. 尿液:用無菌管收集,離心20分鐘左右(2000-3000轉/分)。仔細收集上清,保存過程中如有沉淀形成,應再次離心。胸腹水、腦脊液參照實行。
4. 細胞培養上清:檢測分泌性的成份時,用無菌管收集。離心20分鐘左右(2000-3000轉/分)。仔細收集上清。檢測細胞內的成份時,用PBS(PH7.2-7.4)稀釋細胞懸液,細胞濃度達到100萬/ml左右。通過反復凍融,以使細胞破壞并放出細胞內成份。離心20分鐘左右(2000-3000轉/分)。仔細收集上清。保存過程中如有沉淀形成,應再次離心。
5. 組織標本:切割標本后,稱取重量。加入一定量的PBS,PH7.4。用液氮迅速冷凍保存備用。標本融化后仍然保持2-8℃的溫度。加入一定量的PBS(PH7.4),用手工或勻漿器將標本勻漿充分。離心20分鐘左右(2000-3000轉/分)。仔細收集上清。分裝后一份待檢測,其余冷凍備用。
6. 標本采集后盡早進行提取,提取按相關文獻進行,提取后應盡快進行實驗。若不能馬上進行試驗,可將標本放于-20℃保存,但應避免反復凍融.
7. 不能檢測含NaN3的樣品,因NaN3抑制辣根過氧化物酶的(HRP)活性。
操作步驟
注意事項:
10. 如與英文說明書有異,以英文說明書為準。
計算:
以標準物的濃度為橫坐標,OD值為縱坐標,
在坐標紙上繪出標準曲線,根據樣品的OD
值由標準曲線查出相應的濃度;再乘以稀釋
倍數;或用標準物的濃度與OD值計算出標
準曲線的直線回歸方程式,將樣品的OD值
代入方程式,計算出樣品濃度,再乘以稀釋
倍數,即為樣品的實際濃度。
試劑盒性能:
1.樣品線性回歸與預期濃度相關系數R值為0.95以上。
2.批內變異系數與批間變異系數應分別小于10%和15% 。
檢測范圍:
0.25 pmol/mL - 8 pmol/mL
靈敏度:
檢測濃度小于0.1 pmol/mL
保存條件及有效期:
1.試劑盒保存: 2-8℃。
2.有效期: 6個月
Human ghcagons-like pepfide 1.7-36

Drug Names
Generic Name:Human ghcagons-like pepfide 1.7-36 (GLP-1.7-36) ELISA Kit.
Purpose
This kit allows for the determination of GLP-1.7-36 concentrations in Human serum, plasma, tissue homogenates and other biological fluids.
Principle of the assay
The kit assay Human GLP-1.7-36 level in the sample, use Purified Human GLP-1.7-36 antibody to coat microtiter plate wells, make solid-phase antibody, then add GLP-1.7-36 to the wells, Combined antibody which With HRP labeled, become antibody-antigen-enzyme-antibody complex, after washing Completely, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of GLP-1.7-36 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Specimen requirements
Assay procedure
1. Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well.

3.add enzyme:Add HRP-Conjugate reagent 100μl to each well, except blank well.
4.Incubate: After closing plate with Closure plate membrane ,incubate for 60 min at 37℃.
5.Configurate liquid: 20-fold wash solution diluted 20-fold with distilled water and reserve.
6.washing:Uncover Closure plate membrane, discard Liquid, dry by swing, add washing buffer to every well, still for 30s then drain, repeat 5 times, dry by pat.
7.color:Add Chromogen Solution A 50ul and Chromogen Solution B to each well, evade the light preservation for 15 min at 37℃
8.Stop the reaction:Add Stop Solution 50μl to each well, Stop the reaction(the blue color change to yellow color).
