大鼠血糖（blood glucose）試劑盒操作說明

大鼠血糖(blood glucose)酶聯免疫分析（ELISA）試劑盒使用說明書齊一生物現貨
本試劑僅供研究使用 目的：本試劑盒用于測定大鼠血清，組織及相
關液體樣本中血糖(blood glucose)的含量。
實驗原理：
本試劑盒應用雙抗體夾心法測定標本中大鼠血糖(blood glucose)水平。用純化的大鼠血糖
(blood glucose)抗體包被微孔板，制成固相抗體，往包被單抗的微孔中依次加入血糖(blood
glucose)，再與 HRP 標記的血糖(blood glucose)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zui終的黃色。 顏色的深淺和樣品中的血糖(blood glucose)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大鼠血糖(blood glucose)濃度。

大鼠血糖(blood glucose)酶聯免疫分析（ELISA）試劑盒使用說明書齊一生物現貨樣本處理及要求：
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。2
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
1. 標準品的稀釋與加樣：在酶標包被板上設標準品孔 10孔，在*、第二孔中分別加標
準品 100μl，然后在*、第二孔中加標準品稀釋液 50μl，混勻；然后從*孔、第二
孔中各取 100μl 分別加到第三孔和第四孔， 再在第三、 第四孔分別加標準品稀釋液 50μl，
混勻；然后在第三孔和第四孔中先各取 50μl 棄掉，再各取 50μl 分別加到第五、第六孔
中，再在第五、第六孔中分別加標準品稀釋液 50ul，混勻；混勻后從第五、第六孔中各
取 50μl 分別加到第七、第八孔中，再在第七、第八孔中分別加標準品稀釋液 50μl，混
勻后從第七、第八孔中分別取 50μl 加到第九、第十孔中，再在第九第十孔分別加標準
品稀釋液 50μl，混勻后從第九第十孔中各取 50μl 棄掉。 （稀釋后各孔加樣量都為 50μl，
濃度分別為 480μmol/L，320μmol/L，160μmol/L，80μmol/L，40μmol/L） 。
2. 加樣：分別設空白孔（空白對照孔不加樣品及酶標試劑，其余各步操作相同） 、待測樣
品孔。在酶標包被板上待測樣品孔中先加樣品稀釋液 40μl，然后再加待測樣品 10μl（樣
品zui終稀釋度為 5 倍） 。加樣將樣品加于酶標板孔底部，盡量不觸及孔壁，輕輕晃動混
勻。
3. 溫育：用封板膜封板后置 37℃溫育 30分鐘。
4. 配液：將 30（48T 的 20倍）倍濃縮洗滌液用蒸餾水 30（48T 的 20 倍）倍稀釋后備用。
5. 洗滌：小心揭掉封板膜，棄去液體，甩干，每孔加滿洗滌液，靜置 30 秒后棄去，如此
重復 5次，拍干。
6. 加酶：每孔加入酶標試劑 50μl，空白孔除外。
7. 溫育：操作同 3。
8. 洗滌：操作同 5。
9. 顯色：每孔先加入顯色劑 A50μl，再加入顯色劑 B50μl，輕輕震蕩混勻，37℃避光顯色
15分鐘.
10. 終止：每孔加終止液 50μl，終止反應（此時藍色立轉黃色） 。
11. 測定：以空白空調零，450nm波長依序測量各孔的吸光度（OD 值） 。 測定應在加終止
液后 15分鐘以內進行。
注意事項：
1．試劑盒從冷藏環境中取出應在室溫平衡 15-30 分鐘后方可使用，酶標包被板開封后如未
用完，板條應裝入密封袋中保存。
2．濃洗滌液可能會有結晶析出，稀釋時可在水浴中加溫助溶，洗滌時不影響結果。
3．各步加樣均應使用加樣器，并經常校對其準確性，以避免試驗誤差。一次加樣時間
控制在 5 分鐘內，如標本數量多，推薦使用排槍加樣。
4．請每次測定的同時做標準曲線，做復孔。如標本中待測物質含量過高（樣本 OD 值
大于標準品孔*孔的 OD 值） ，請先用樣品稀釋液稀釋一定倍數（n倍）后再測定，計
算時請zui后乘以總稀釋倍數（×n×5） 。
5．封板膜只限一次性使用，以避免交叉污染。
6．底物請避光保存。3
7．嚴格按照說明書的操作進行，試驗結果判定必須以酶標儀讀數為準.
8．所有樣品，洗滌液和各種廢棄物都應按傳染物處理。
9．本試劑不同批號組分不得混用。
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。

Generic Name：Rat blood glucose ELISA Kit.
Purpose
This kit allows for the determination of blood glucose concentrations in Rat
serum, tissue, and other biological fluids.
Principle of the assay
The kit assay Rat blood glucose level in the sample，use Purified Rat
blood glucose antibody to coat microtiter plate wells, make solid-phase
antibody, then add blood glucose to wells, Combined blood glucose antibody
which With HRP labeled, become antibody - antigen - enzyme-antibody
complex, after washing Compley, 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 blood glucose in the samples is then determined by
comparing the O.D. of the samples to the standard curve.5

well discard(add Sample 50μl to each well after Diluting ,(density: 480μmol/L，
320μmol/L，160μmol/L，80μmol/L，40μmol/L)
2.add sample：Set blank wells separay (blank comparison wells don’t add
sample and HRP-Conjugate reagent, other each step operation is same).
testing sample well. add Sample dilution 40μl to testing sample well, then add
testing sample 10μl (sample final dilution is 5-fold), add sample to wells ,
don’t touch the well wall as far as possible, and Gently mix.
3.Incubate: After closing plate with Closure plate membrane ,incubate for 30
min at 37℃.
4.Configurate liquid: 30-fold (or 20-fold)wash solution diluted 30-fold (or 20-fold)
with distilled water and reserve.

add washing buffer to every well, still for 30s then drain, repeat 5 times, dry by
pat.
6.add enzyme：Add HRP-Conjugate reagent 50μl to each well, except blank
well.
7.incubate：Operation with 3.
8.washing：Operation with 5.
9.color：Add Chromogen Solution A 50ul and Chromogen Solution B to each
well, evade the light preservation for 15 min at 37℃
10.Stop the reaction： Add Stop Solution50μl to each well, Stop the reaction(the
blue color change to yellow color).
11.assay：take blank well as zero , Read absorbance at 450nm after Adding
Stop Solution and within 15min.
Important notes
1. The kit takes out from the refrigeration environment should be balanced
15-30 minutes in the room temperature, ELISA plates coated if has not use
up after opened, the plate should be stored in Sealed bag.
2. washing buffer will Crystallization separation, it can be heated the water8
helps dissolve when dilute . Washing does not affect the result.
3. add Sample with sampler Each step, And proofread its accuracy frequently,
avoids the experimental error. add sample within 5 mins, if the number of
sample is much , recommend to use Volley .
4. if the testing material content is excessively higher (The sample OD is
bigger than the first standard well ),please dilute Sample (n-fold), Please
diluente and multiplied by the dilution factor.（×n×5）.
5. Closure plate membrane only limits the disposable use, to avoid
cross-contamination.
6. The substrate evade the light preservation.
7. Please according to use instruction strictly, The test result determination
must take the microtiter plate reader as a standard.
8. All samples, washing buffer and each kind of reject should according to
infective material process.
9. Do not mix reagents with those from other lots.
