計(ji)算(suan):
以標(biao)準物(wu)的(de)(de)濃(nong)度為橫坐(zuo)(zuo)標(biao),OD值為縱坐(zuo)(zuo)標(biao),在坐(zuo)(zuo)標(biao)紙(zhi)上繪出標(biao)準曲線,根據樣品的(de)(de)OD值由(you)標(biao)準曲線查出相應的(de)(de)濃(nong)度;再(zai)乘以稀釋倍數(shu);或用標(biao)準物(wu)的(de)(de)濃(nong)度與OD值計算出標(biao)
準曲線(xian)的直(zhi)線(xian)回歸方程式(shi),將樣(yang)品(pin)的OD值(zhi)代入方程式(shi),計(ji)算出樣(yang)品(pin)濃度,再(zai)乘以稀釋(shi)
倍數,即為(wei)樣品的實際濃度(du)。
注(zhu)意事項:
1. 試劑盒從冷藏環境中取出應(ying)在室溫(wen)平衡(heng)15-30分鐘(zhong)后(hou)方可使用,酶(mei)標(biao)包被(bei)板(ban)開封后(hou)如(ru)未用完(wan),板(ban)條(tiao)應(ying)裝(zhuang)入(ru)密封袋中保(bao)存。
2. 濃洗(xi)滌(di)液可能會有結晶析出,稀釋(shi)時(shi)可在水(shui)浴中加溫助(zhu)溶,洗(xi)滌(di)時(shi)不影響結果。
3. 各步加樣均應使用加樣器,并經常校對其準(zhun)確(que)性,以避免試驗誤(wu)差。一次加樣時(shi)間控(kong)制在5分(fen)鐘內,如標本(ben)數量多(duo),推薦使用排槍加樣。
4. 請(qing)每次(ci)測定的同時做(zuo)標(biao)準(zhun)曲線,做(zuo)復孔。如標(biao)本(ben)中(zhong)待測物(wu)質含量過高(樣本(ben)OD值(zhi)大于標(biao)準(zhun)品孔*孔的OD值(zhi)),請(qing)先用樣品稀釋液(ye)稀釋一定倍數(n倍)后再測定,計算時請(qing)zui后乘以總(zong)稀釋倍數(×n×5)。
5. 封板(ban)膜只限一次性使用,以避免交叉污(wu)染。
6. 底(di)物(wu)請避光保存。
7. 嚴格按(an)照(zhao)說明書(shu)的操(cao)作進(jin)行,試驗(yan)結(jie)果判定必須(xu)以酶(mei)標(biao)儀讀數為準.
8. 所有樣品,洗滌(di)液和各種廢棄(qi)物(wu)都應按(an)傳染(ran)物(wu)處理。
