4、標準品加入 150l 標準品稀釋液2.加樣：分別設空白孔（空白對照孔不加樣品及酶標試劑，其余各步操作相同） 、標準孔、待測樣品孔。在酶標包被板上標準品準確加樣 50l，待測樣品孔中先加樣品稀釋液40l，然后再加待測樣品 10l（樣品最終稀釋度為 5 倍） 。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 倍濃縮洗滌液用蒸餾水 30 倍稀釋后備用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 50l，空白孔除外。 7.溫育：操作同

5、3。8.洗滌：操作同 5。9.顯色：每孔先加入顯色劑 A50l，再加入顯色劑 B50l，輕輕震蕩混勻，37避光顯色15 分鐘.10. 終止：每孔加終止液 50l，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。操作程序總結：操作程序總結：計算計算 以標準物的濃度為橫坐標，OD 值為縱坐標，在坐標紙上繪出標準曲線，根據(jù)樣品的OD 值由標準曲線查出相應的濃度；再乘以稀釋倍數(shù)；或用標準物的濃度與 OD 值計算出標準曲線的直線回歸方程式，將樣品的 OD 值代入方程式，計算出樣品濃度，再乘以稀釋倍數(shù)

6、，即為樣品的實際濃度。 注意事項注意事項1試劑盒從冷藏環(huán)境中取出應在室溫平衡 15-30 分鐘后方可使用，酶標包被板開封后如未用完，板條應裝入密封袋中保存。2濃洗滌液可能會有結晶析出，稀釋時可在水浴中加溫助溶，洗滌時不影響結果。3各步加樣均應使用加樣器，并經(jīng)常校對其準確性，以避免試驗誤差。一次加樣時間最好控制在 5 分鐘內，如標本數(shù)量多，推薦使用排槍加樣。4 請每次測定的同時做標準曲線，最好做復孔。如標本中待測物質含量過高（樣本 OD值大于標準品孔第一孔的 OD 值） ，請先用樣品稀釋液稀釋一定倍數(shù)（n 倍）后再測定，計算時請最后乘以總稀釋倍數(shù)（n5） 。5 封板膜只限一次性使用，以避免交叉污

7、染。6底物請避光保存。7嚴格按照說明書的操作進行，試驗結果判定必須以酶標儀讀數(shù)為準.8所有樣品，洗滌液和各種廢棄物都應按傳染物處理。9本試劑不同批號組分不得混用。10. 如與英文說明書有異，以英文說明書為準。保存條件及有效期保存條件及有效期1試劑盒保存：；2-8。2有效期：6 個月Rat froctosamine（FA）FOR RESEARCH USE ONLYAssay range：50mol/L - 1600mol/L 96 determinationsPurposeThis kit allows for the determination of FA concentrations in
