試劑盒樣本要求
在收集標(biāo)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(wěn)定。我們提倡新鮮標(biāo)本盡早檢測,對收集后當(dāng)天就進行檢測的標(biāo)本,及時儲存在4℃?zhèn)溆茫缬刑厥庠蛐枰芷谑占瘶?biāo)本,請造模取材后,將標(biāo)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(zhì)量,所以避免反復(fù)凍融。具體操作注意事項請與我司技術(shù)人員溝通。齊一生物銷售:021-6034 8496;181214 53965;173021 04490
【人黑素瘤衍生亮氨酸拉鏈額外核因子(MLZE)ELISA試劑盒現(xiàn)貨】液體類標(biāo)本:標(biāo)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(xì)胞培養(yǎng)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(zhuǎn)/分)。仔細(xì)收集上清。保存過程中如有沉淀形成,應(yīng)再次離心。
2. 血漿:應(yīng)根據(jù)標(biāo)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(zhuǎn)/分)。仔細(xì)收集上清。保存過程中如有沉淀形成應(yīng)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(zhuǎn)/分)。仔細(xì)收集上清。如有沉淀形成,應(yīng)再次離心。
4. 細(xì)胞培養(yǎng)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(zhuǎn)/分)。仔細(xì)收集上清。
5. 培養(yǎng)細(xì)胞:檢測細(xì)胞內(nèi)的成份時,用PBS(PH7.2-7.4)稀釋細(xì)胞懸液,細(xì)胞濃度達到100萬/ml左右。通過反復(fù)凍融或加入組織蛋白萃取試劑,以使細(xì)胞破壞并放出細(xì)胞內(nèi)成份。離心20分鐘左右(2000-3000轉(zhuǎn)/分)。仔細(xì)收集上清。保存過程中如有沉淀形成,應(yīng)再次離心。
6. 組織標(biāo)本:切割標(biāo)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(biāo)本勻漿充分。離心20分鐘左右(2000-3000轉(zhuǎn)/分)。仔細(xì)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(biāo)本采集后盡早進行提取,提取按相關(guān)文獻進行,提取后應(yīng)盡快進行實驗。若不能馬上進行試驗,可將標(biāo)本放于-20℃保存,但應(yīng)避免反復(fù)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(yīng)將其分裝,-70 ℃保存,避免反復(fù)冷凍。保存過程中如出現(xiàn)沉淀,應(yīng)再次離心。血液標(biāo)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(yīng)在室溫下解凍并確保樣品均勻地充分解凍。
