654次人表皮生長因子受體(EGFR)酶聯免疫分析試劑盒使用說明書
本試劑盒僅供研究使用。
檢測范圍: 48T
0.1μg/L -8μg/L
使用目的:
本試劑盒用于測定人血清、血漿及相關液體樣本中表皮生長因子受體(EGFR)含量。
實驗原理
本試劑盒應用雙抗體夾心法測定標本中人表皮生長因子受體(EGFR)水平。用純化的人表皮生長因子受體(EGFR)抗體包被微孔板,制成固相抗體,往包被單抗的微孔中依次加入表皮生長因子受體(EGFR),再與HRP標記的表皮生長因子受體(EGFR)抗體結合,形成抗體-抗原-酶標抗體復合物,經過*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉化成藍色,并在酸的作用下轉化成zui終的。顏色的深淺和樣品中的表皮生長因子受體(EGFR)呈正相關。用酶標儀在450nm波長下測定吸光度(OD值),通過標準曲線計算樣品中人表皮生長因子受體(EGFR)濃度。

標本要求
1.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
2.不能檢測含NaN3的樣品,因NaN3抑制辣根過氧化物酶的(HRP)活性。
操作步驟
8μg/L | 5號標準品 | 150μl的原倍標準品加入150μl標準品稀釋液 |
4μg/L | 4號標準品 | 150μl的5號標準品加入150μl標準品稀釋液 |
2μg/L | 3號標準品 | 150μl的4號標準品加入150μl標準品稀釋液 |
1μg/L | 2號標準品 | 150μl的3號標準品加入150μl標準品稀釋液 |
0.5μg/L | 1號標準品 | 150μl的2號標準品加入150μl標準品稀釋液 |
操作程序總結:
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,根據樣品的OD值由標準曲線查出相應的濃度;再乘以稀釋倍數;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,即為樣品的實際濃度。
注意事項
1.試劑盒從冷藏環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,并經常校對其準確性,以避免試驗誤差。一次加樣時間控制在5分鐘內,如標本數量多,推薦使用排槍加樣。
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
1.試劑盒保存:;2-8℃。

Human EGFR
FOR RESEARCH USE ONLY
Assay range:0.1μg/L -8μg/L 96 determinations
Purpose
This kit allows for the determination of EGFR concentrations in Human serum, cell culture supernates and other biological fluids
Principle of the assay
The kit assay Human EGFR level in the sample,use Purified Human EGFR antibody to coat microtiter plate wells, make solid-phase antibody, then add EGFR to wells, Combined EGFR antibody which With HRP labeled goat anti-Human become antibody - antigen - enzyme-antibody complex, after washing Compley, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of EGFR in the samples is then determined by comparing the O.D. of the samples to the standard curve.
