643次人表皮生長因子受體(EGFR)酶聯(lián)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(guān)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(yīng)用雙抗體夾心法測定標(biāo)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(biāo)記的表皮生長因子受體(EGFR)抗體結(jié)合,形成抗體-抗原-酶標(biāo)抗體復(fù)合物,經(jīng)過*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉(zhuǎn)化成藍(lán)色,并在酸的作用下轉(zhuǎn)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(guān)。用酶標(biāo)儀在450nm波長下測定吸光度(OD值),通過標(biāo)準(zhǔn)曲線計算樣品中人表皮生長因子受體(EGFR)濃度。

操作程序總結(jié):
計算
以標(biāo)準(zhǔn)物的濃度為橫坐標(biāo),OD值為縱坐標(biāo),在坐標(biāo)紙上繪出標(biāo)準(zhǔn)曲線,根據(jù)樣品的OD值由標(biāo)準(zhǔn)曲線查出相應(yīng)的濃度;再乘以稀釋倍數(shù);或用標(biāo)準(zhǔn)物的濃度與OD值計算出標(biāo)準(zhǔn)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),即為樣品的實際濃度。
注意事項
1.試劑盒從冷藏環(huán)境中取出應(yīng)在室溫平衡15-30分鐘后方可使用,酶標(biāo)包被板開封后如未用完,板條應(yīng)裝入密封袋中保存。
2.濃洗滌液可能會有結(jié)晶析出,稀釋時可在水浴中加溫助溶,洗滌時不影響結(jié)果。
3.各步加樣均應(yīng)使用加樣器,并經(jīng)常校對其準(zhǔn)確性,以避免試驗誤差。一次加樣時間控制在5分鐘內(nèi),如標(biāo)本數(shù)量多,推薦使用排槍加樣。
6.底物請避光保存。
7.嚴(yán)格按照說明書的操作進(jìn)行,試驗結(jié)果判定必須以酶標(biāo)儀讀數(shù)為準(zhǔn).
8.所有樣品,洗滌液和各種廢棄物都應(yīng)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(zhǔn)。
