ELISA試劑盒問題描述

標準曲線梯度差：

吸液或加液不準請檢查移液器及吸頭

標準品稀釋不正確溶解標準品稍微旋轉瓶身，輕輕混勻使粉末完全溶解

洗滌不完全保證洗滌時間和洗滌次數及每孔的加液量

顯色很弱或無色：

孵育時間太短保證充足的孵育時間

實驗溫度不正確使用推薦的實驗溫度

試劑體積不夠或漏加、稀釋不正確檢查吸液及加液過程，保證所有試劑按順序足量添加

讀數數值低：

酶標儀設置不正確 在酶標儀上檢查波長及濾光片設置

提前打開酶標儀預熱：變異系數大加液不正確檢查加液情況

【人補體片段3c（C3c）ELISA試劑盒】背景值高：

檢測抗體的工作濃度使用推薦的稀釋倍數

酶標板洗滌不完全重新閱讀操作手冊，保證清洗完全；如果用自動洗板機，請檢查所有的出口是否有堵塞

洗液有污染配制新鮮的洗液

靈敏度低：

ELISA試劑盒保存按說明書要求保存相關試劑

讀數前未終止OD讀數前應在每孔中加入終止液

齊一生物客戶寄標本時需注明以下情況：

1、標本編號；2、所測項目；3、是否做復孔；3、聯系方式；4、實驗后標本是否寄回。

客戶必知：

客戶應對所提供的材料及信息負責，如因客戶提供的材料及信息不準確而引起的實驗延誤或經濟損失由客戶承擔。

試劑盒樣本要求

在收集標本前都必須有一個完整的計劃，必須清楚要檢測的成份是否足夠穩定。我們提倡新鮮標本盡早檢測，對收集后當天就進行檢測的標本，及時儲存在4℃備用，如有特殊原因需要周期收集標本，請造模取材后，將標本及時分裝后放在-20℃或-70℃條件下保存。因冰室與室溫存在一定溫差，蛋白極易降解，直接影響實驗質量，所以避免反復凍融。具體操作注意事項請與我司技術人員溝通。齊一生物銷售：021－6034 8496；181214 53965；173021 04490

【人補體片段3c（C3c）ELISA試劑盒】液體類標本：標本必須為液體，不含沉淀。包括血清、血漿、尿液、胸腹水、腦脊液、細胞培養上清、組織勻漿等。

1. 血清：室溫血液自然凝固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，應再次離心。

2. 血漿：應根據標本的要求選擇EDTA、檸檬酸鈉或肝素作為抗凝劑，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再次離心。

3. 尿液、胸腹水、腦脊液：用無菌管收集。離心20分鐘左右（2000-3000轉/分）。仔細收集上清。如有沉淀形成，應再次離心。

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。

5. 培養細胞: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。通過反復凍融或加入組織蛋白萃取試劑，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。

6. 組織標本：切割標本后，稱取重量。加入一定量的PBS，緩沖液中可加入1μg/L蛋白酶抑制劑或50U/ml的Aprotinin（抑肽酶）。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）。仔細收集上清置于-20度或-70度保存，如有必要，可以將樣品濃縮干燥。分裝后一份待檢測，其余冷凍備用。

7. 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

8.不能檢測含NaN3的樣品，因NaN3抑制辣根過氧化物酶的（HRP）活性。

9.如果樣品不能立即檢測，應將其分裝，-70 ℃保存，避免反復冷凍。保存過程中如出現沉淀，應再次離心。血液標本盡可能的不要使用溶血或高血脂血。如果血清中含大量顆粒，檢測前先離心或過濾。不要在37℃或更高的溫度加熱解

凍。應在室溫下解凍并確保樣品均勻地充分解凍。
