人CD3分子酶聯免疫分析試劑盒樣本處理方法:
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。
