試劑盒使用說明書
貨號: HY10786
本試劑盒用于體外定量檢測人血清、血漿、組織、細(xì)胞上清及相關(guān)液體樣本中NSE的含量。
本試劑盒用于體外定量檢測人血清、血漿、組織、細(xì)胞上清及相關(guān)液體樣本中NSE的含量。
本試劑盒應(yīng)用雙抗體夾心法測定標(biāo)本中人NES水平。用純化的人NES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NES，再與HRP標(biāo)記的NSE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終的黃色。顏色的深淺和樣品中的NSE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NSE濃度。
l 本試劑盒僅用于科研，不得用于醫(yī)學(xué)診斷。
l 使用試劑盒前，請仔細(xì)閱讀說明書，以試劑盒內(nèi)的說明書為準(zhǔn)，請務(wù)必理解說明書內(nèi)容。
l 酶標(biāo)包被板屬于可拆型，開封后如未用完，板條應(yīng)裝入鋁箔袋密封并2°C-8°C保存。
l 加樣樣本和試劑應(yīng)盡快，每一步加樣都根據(jù)相同的序列。Pipetting of samples and reagents must be done as quickly as possible and in the same sequence for each step.
l Use reservoirs only for single reagents. This especially applies to the substrate reservoirs. Using a reservoir for dispensing a substrate solution that had previously been used for the conjugate solution may turn solution colored. Do not pour reagents back into vials as reagent contamination may occur.
l Mix the contents of the microplate wells thoroughly to ensure good test results. Do not reuse microwells.
l 避免實驗過程中酶標(biāo)板干燥；清洗后盡快加試劑。Do not let wells dry during assay; add reagents immediay after completing the rinsing steps.
l 實驗開始，所有試劑應(yīng)平衡到室溫 （21-26°C） 后方可進(jìn)行。溫度會影響吸光度值，但不影響樣本值。Allow the reagents to reach room temperature （21-26°C） before starting the test. Temperature will affect the absorbance readings of the assay. However, values for the patient samples will not be affected.
l 切忌用口加樣，以免試劑和樣本粘到皮膚和粘膜上。Never pipet by mouth and avoid contact of reagents and specimens with skin and mucous membranes.
l 不要在處理樣本或試劑的區(qū)域抽煙、吃東西、喝酒或化妝。Do not smoke, eat, drink or apply cosmetics in areas where specimens or kit reagents are handled.
l 操作時帶一次性手套，微生物的污染會影響實驗結(jié)果的正確性。Wear disposable latex gloves when handling specimens and reagents. Microbial contamination of reagents or specimens may give false results.
l 操作應(yīng)按照國家規(guī)定的微生物安全條列進(jìn)行。Handling should be done in accordance with the procedures defined by an appropriate national biohazard safety guideline or regulation.
l 過期的試劑盒切勿再使用。Do not use reagents beyond expiry date as shown on the kit labels.
l All indicated volumes have to be performed according to the protocol. Optimal test results are only obtained when using calibrated pipettes and microtiterplate readers.
l Do not mix or use components from kits with different lot numbers. It is advised not to exchange wells of different plates even of the same lot. The kits may have been shipped or stored under different conditions and the binding characteristics of the plates may result slightly different.
l Avoid contact with Stop Solution containing 0.5 M H2SO4. It may cause skin irritation and burns.
l 含有防腐劑、BND或者類似防腐劑MIT的試劑Some reagents contain Proclin, BND and/or MIT as preservatives. In case of contact with eyes or skin, flush immediay with water.
l TMB 底物對皮膚有刺激性，不慎入眼，立即用大量水沖洗，皮膚上不慎接觸到也應(yīng)立即用肥皂，并用大量的水沖洗。試驗中被污染的物品在下次使用前應(yīng)盡快清洗。TMB substrate has an irritant effect on skin and mucosa. In case of possible contact, wash eyes with an abundant volume of water and skin with soap and abundant water. Wash contaminated objects before reusing them. If inhaled, take the person to open air.
l 配置的化學(xué)品或使用后的試劑，根據(jù)國家微生物安全條列都視為危險廢物。Chemicals and prepared or used reagents have to be treated as hazardous waste according to the national biohazard safety guideline or regulation.
l 參照材料安全系數(shù)表知道試劑盒里的有害物質(zhì)。For information on hazardous substances included in the kit please refer to Material Safety Data Sheets

u 注意事項
l 所有試劑和樣本使用前必須在室溫下平衡，混勻試劑時不應(yīng)起泡沫。All reagents and specimens must be allowed to come to room temperature before use. All reagents must be mixed without foaming.
l 一旦實驗開始，各操作步驟都應(yīng)盡快完成。Once the test has been started, all steps should be completed without interruption.
l 避免重復(fù)使用手中的吸頭和試管，以免交叉污染。Use new disposal plastic pipette tips for each standard, control or sample in order to avoid cross contamination.
l 吸光度值是溫育時間和溫度的函數(shù)，實驗開始前，準(zhǔn)備好所有的試劑，Absorbance is a function of the incubation time and temperature. Before starting the assay, it is recommended that all reagents are ready, caps removed, all needed wells secured in holder, etc. This will ensure equal elapsed time for each pipetting step without interruption.
l 一般情況，酶的反應(yīng)與時間和溫度成正比。As a general rule the enzymatic reaction is linearly proportional to time and temperature.
l Determine absorption with an ELISA reader at 450 nm against 620 nm as reference. If no reference wavelength is available, read only at 450nm. If the extinction of the highest standard exceeds the measurement range of the photometer, absorption must be measured immediay at 405 nm against 620 nm as reference.
u 操作步驟
1. 加標(biāo)準(zhǔn)品：在酶標(biāo)包被板上設(shè)標(biāo)準(zhǔn)品孔，依次加入不同濃度的標(biāo)準(zhǔn)品50ul（建議每個濃度做2個平行孔）。
2. 加樣：分別設(shè)空白孔（空白對照孔不加樣品及酶標(biāo)試劑，其余各步操作相同）、待測樣品孔。在酶標(biāo)包被板上待測樣品孔中先加樣品40μl，然后再加樣品親和素10μl。加樣將樣品加于酶標(biāo)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(fù)5次，拍干。
6. 加酶：每孔加入酶標(biāo)試劑50μl，空白孔除外。
7. 溫育：操作同3。
8. 洗滌：操作同5。
9. 顯色：每孔先加入顯色劑A50μl，再加入顯色劑B50μl，輕輕震蕩混勻，37℃避光顯色15分鐘.
10. 終止：每孔加終止液50μl，終止反應(yīng)（此時藍(lán)色立轉(zhuǎn)黃色）。
11. 測定：以空白空調(diào)零，450nm波長依序測量各孔的吸光度（OD值）。 測定應(yīng)在加終止液后15分鐘以內(nèi)進(jìn)行
