人紅細胞生成素受體受體抗體(EPOR-Ab)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，血漿及相關
液體樣本中紅細胞生成素受體抗體(EPOR-Ab)水平。
實驗原理：
本試劑盒采用雙抗原夾心酶聯免疫法（ELISA）測定標本中人紅細胞生成素受體抗體
(EPOR-Ab)。用純化的人紅細胞生成素受體 (EPOR)抗原包被微孔板，制成固相抗原，可與樣
品中紅細胞生成素受體抗體(EPOR-Ab)相結合，經洗滌除去未結合的抗體和其他成分后再與
HRP 標記的紅細胞生成素受體 (EPOR)抗原結合，形成抗原-抗體-酶標抗原復合物，經過徹
底洗滌后加底物 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。用酶標儀在 450nm 波長下測定吸光度（OD 值） ，與 CUTOFF 值相比較，從而
判定標本中人紅細胞生成素受體抗體(EPOR-Ab)的存在與否。

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。2
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：
1. 編號：將樣品對應微孔按序編號，每板應設陰性對照 2孔、陽性對照 2 孔、空白對照 1
孔（空白對照孔不加樣品及酶標試劑，其余各步操作相同）
2. 加樣：分別在陰、陽性對照孔中加入陰性對照、陽性對照 50μl。然后在待測樣品孔先
加樣品稀釋液 40μl，然后再加待測樣品 10μl。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）倍濃縮洗滌液加蒸餾水至 600ml 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 A 50μl，再加入顯色劑 B 50μl，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。
結果判定：
試驗有效性：陽性對照孔平均值≥1.00; 陰性對照平均值≤0.10
臨界值（CUT OFF）計算：臨界值=陰性對照孔平均值+0.15
陰性判定：樣品 OD 值< 臨界值（CUT OFF）者為人紅細胞生成素受體抗體(EPOR-Ab)
陰性
陽性判定：樣品 OD 值≥ 臨界值（CUT OFF）者為人紅細胞生成素受體抗體(EPOR-Ab)
陽性

antigen which with HRP labeled become antigen – antibody - enzyme-antigen
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. Compared with
the CUTOFF value, according to this to judge EPOR -Ab exist in the sample or

Assay procedure
1.Number: to sample correspond microtitration well and Number Sequence,
each plate should be set feminine comparison 2 wells, masculine comparison
2 wells, blank comparison 1 well(don’t add sample and HRP-Conjugate
reagent to blank comparison well, other each step the operation are same).
2.add sample：separay add Positive control and Negative control 50μl to the
Positive and Negative well . add Sample dilution 40μl to testing sample well,
then add testing sample 10μl. add sample to the bottom of ELISA plates7
coated well , 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 until 600ml,and
reserve.
5.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.
6.add enzyme： Add HRP-Conjugate reagent 50μlto each well, except the 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.
Determine the result
Test validity: the average of Positive control well≥1.00; the average of
Negative control well ≤0.10.
Calculate Critical(CUT OFF) : Critical= the average of Negative control well
+ 0.15.
Negative control: sample OD< Calculate Critical(CUT OFF) is EPOR -Ab
Negative control.
Positive control: ample OD≥ Calculate Critical(CUT OFF) is EPOR -Ab8
Positive control.
Important notes
1.Please according to use instruction strictly, Do not mix reagents with those
from other lots.
2.The kit takes out from the refrigeration environment should be balanced
15-30 minutes in the room temperature then use, ELISA plates coated if
has not use up after opened, the plate should be stored in Sealed bag.
3.washing buffer will Crystallization separation, it can be heated the water
helps dissolve when dilute . Washing does not affect the result.
4.Closure plate membrane only limits the disposable use, in order to avoid
the overlapping pollution
5.The substrate please evade the light preservation.
6.The test result determination must take the microtiter plate reader as a
standard, when use dual-wavelength to assay, Reference wavelength is
630nm.
7.All samples, washing buffer and each kind of reject should according to
infective material process. Stopp Solution is 2M sulphuric acid. You must pay
attention to safe when use .
