小鼠(Mouse)(HYD) ELISA检测试剂盒
- 操作步骤:使用前,将所有试剂充分混匀。不要使液体产生大量的泡沫,以免加样时加入大量的气泡,产生加样上的误差。根据待测样品数量加上标准品的数量决定所需的板条数。每个标准品和空白孔建议做复孔。每个样品根据自己的数量来定,能使用复孔的尽量做复孔。加入稀释好后的标准品50ul于反应孔、加入待测样品50ul于反应孔内。立即加入50ul的生物素标记的抗体。盖上膜板,轻轻振荡混匀,37℃温育45分钟。甩去孔内液体,每孔加满洗涤液,振荡30秒,甩去洗涤液,用吸水纸拍干。重复此操作4次。如果用洗板机洗涤,洗涤次数增加一次。每孔加入100ul的亲和链酶素-HRP,轻轻振荡混匀,37℃温育30分钟。甩去孔内液体,每孔加满洗涤液,振荡30秒,甩去洗涤液,用吸水纸拍干。重复此操作4次。如果用洗板机洗涤,洗涤次数增加一次。每孔加入底物A、B各50ul,轻轻振荡混匀,37℃温育5分钟。避免光照。取出酶标板,迅速加入50ul终止液,加入终止液后应立即测定结果。在450nm波长处测定各孔的OD值。小鼠(Mouse)(HYD)ELISA检测试剂盒结果判断与分析:仪器值:于波长450nm的酶标仪上读取各孔的OD值以吸光度OD值为纵坐标(Y),相应的HYD标准品浓度为横坐标(X),做得相应的曲线,样品的HYD含量可根据其OD值由标准曲线换算出相应的浓度,再乘以稀释倍数;或用标准物的浓度与OD值计算出标准曲线的回归方程式,将样品的OD值代入方程式,计算出样品浓度,再乘以稀释倍数,即为样品的实际浓度。[详细]

[ELISA]CD8分子(CD8)ELISA Kit
- 羊CD8分子(CD8)试剂盒使用说明书本试剂盒仅供研究使用。检测范围:96T7IU/ml-240IU/ml试剂盒组成130倍浓缩洗涤液20ml×1瓶7终止液6ml×1瓶2酶标试剂6ml×1瓶8标准品(400IU/ml)0.5ml×1瓶3酶标包被板12孔×8条9标准品稀释液1.5ml×1瓶4样品稀释液6ml×1瓶10说明书1份5显色剂A液6ml×1瓶11封板膜2张6显色剂B液6ml×1/瓶12密封袋1个标本要求1.标本采集后尽早进行提取,提取按相关文献进行,提取后应尽快进行实验。若不能马上进行试验,可将标本放于-20℃保存,但应避免反复冻融2.不能检测含NaN3的样品,因NaN3YZ辣根过氧化物酶的(HRP)活性。羊CD8分子ELISA试剂盒用于测定羊血清、血浆及相关液体样本中CD8分子(CD8)含量。操作步骤1.标准品的稀释:本试剂盒提供原倍标准品一支,用户可按照下列图表在小试管中进行稀释。200IU/ml5号标准品150μl的原倍标准品加入150μl标准品稀释液100IU/ml4号标准品150μl的5号标准品加入150μl标准品稀释液50IU/ml3号标准品150μl的4号标准品加入150μl标准品稀释液25IU/ml2号标准品150μl的3号标准品加入150μl标准品稀释液12.5IU/ml1号标准品150μl的2号标准品加入150μl标准品稀释液2.加样:分别设空白孔(空白对照孔不加样品及酶标试剂,其余各步操作相同)、标准孔、待测样品孔。在酶标包被板上标准品准确加样50μl,待测样品孔中先加样品稀释液40μl,然后再加待测样品10μl(样品Z终稀释度为5倍)。加样将样品加于酶标板孔底部,尽量不触及孔壁,轻轻晃动混匀。3.温育:用封板膜封板后置37℃温育30分钟。4.配液:将30倍浓缩洗涤液用蒸馏水30倍稀释后备用5.洗涤:小心揭掉封板膜,弃去液体,甩干,每孔加满洗涤液,静置30秒后弃去,如此重复5次,拍干。6.加酶:每孔加入酶标试剂50μl,空白孔除外。7.温育:操作同3。8.洗涤:操作同5。9.显色:每孔先加入显色剂A50μl,再加入显色剂B50μl,轻轻震荡混匀,37℃避光显色15分钟.10.终止:每孔加终止液50μl,终止反应(此时蓝色立转黄色)。11.测定:以空白空调零,450nm波长依序测量各孔的吸光度(OD值)。测定应在加终止液后15分钟以内进行。羊CD8分子ELISA试剂盒注意事项1.试剂盒从冷藏环境中取出应在室温平衡15-30分钟后方可使用,酶标包被板开封后如未用完,板条应装入密封袋中保存。2.浓洗涤液可能会有结晶析出,稀释时可在水浴中加温助溶,洗涤时不影响结果。3.各步加样均应使用加样器,并经常校对其准确性,以避免试验误差。一次加样时间**控制在5分钟内,如标本数量多,推荐使用排枪加样。4.请每次测定的同时做标准曲线,**做复孔。如标本中待测物质含量过高(样本OD值大于标准品孔**孔的OD值),请先用样品稀释液稀释一定倍数(n倍)后再测定,计算时请Z后乘以总稀释倍数(×n×5)。5.封板膜只限一次性使用,以避免交叉污染。6.底物请避光保存。7.严格按照说明书的操作进行,试验结果判定必须以酶标仪读数为准.8.所有样品,洗涤液和各种废弃物都应按传染物处理。9.本试剂不同批号组分不得混用。10.如与英文说明书有异,以英文说明书为准。保存条件及有效期1.试剂盒保存:;2-8℃。2.有效期:6个月羊CD8分子ELISA试剂盒应用双抗体夹心法测定标本中羊CD8分子(CD8)水平。用纯化的羊CD8分子(CD8)抗体包被微孔板,制成固相抗体,往包被单抗的微孔中依次加入CD8分子(CD8),再与HRP标记的CD8分子(CD8)抗体结合,形成抗体-抗原-酶标抗体复合物,经过彻底洗涤后加底物TMB显色。TMB在HRP酶的催化下转化成蓝色,并在酸的作用下转化成Z终的黄色。颜色的深浅和样品中的CD8分子(CD8)呈正相关。用酶标仪在450nm波长下测定吸光度(OD值),通过标准曲线计算样品中羊CD8分子(CD8)浓度。[详细]
