【人粒细胞巨噬细胞集落刺激因子抗体(GM-CSFAb)ELISA试剂盒现货】实验原理:
本试剂盒应用双抗体夹心法测定标本中该产品水平.用纯化的本产品抗体包被微孔板,制成固相抗体,往包被单抗的微孔中依次加入本产品抗原,再与HRP标记的本产品抗体结合,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*终的黄色.颜色的深浅和样品中的本产品呈正相关.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该产品浓度.

【人粒细胞巨噬细胞集落刺激因子抗体(GM-CSFAb)ELISA试剂盒现货】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NaN3抑制辣根过氧化物酶的(HRP)活性.
操作步骤:
1. 标准品的稀释与加样:在酶标包被板上设标准品孔10孔,在、第二孔中分别加标准品100μl,然后在、第二孔中加标准品稀释液50μl,混匀;然后从孔、第二孔中各取100μl分别加到第三孔和第四孔,再在第三、第四孔分别加标准品稀释液50μl,混匀;然后在第三孔和第四孔中先各取50μl弃掉,再各取50μl分别加到第五、第六孔中,再在第五、第六孔中分别加标准品稀释液50ul,混匀;混匀后从第五、第六孔中各取50μl分别加到第七、第八孔中,再在第七、第八孔中分别加标准品稀释液50μl,混匀后从第七、第八孔中分别取50μl加到第九、第十孔中,再在第九第十孔分别加标准品稀释液50μl,混匀后从第九第十孔中各取50μl弃掉.(稀释后各孔加样量都为50μl,浓度分别为1200 ng/L,800 ng/L ,400 ng/L,200ng/L, 100 ng/L). 【人粒细胞巨噬细胞集落刺激因子抗体(GM-CSFAb)ELISA试剂盒现货】
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)、待测样品孔.在酶标包被板上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*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(48T的20倍)倍浓缩洗涤液用蒸馏水30(48T的20倍)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.
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. 【人粒细胞巨噬细胞集落刺激因子抗体(GM-CSFAb)ELISA试剂盒现货】
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,推荐使用排抢加样.
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*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.
计算:
以标准物的浓度为横坐标,OD值为纵坐标,
在坐标纸上绘出标准曲线,根据样品的OD
值由标准曲线查出相应的浓度;再乘以稀释
倍数;或用标准物的浓度与OD值计算出标
准曲线的直线回归方程式,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.
试剂盒性能:
1.样品线性回归与预期浓度相关系数R值为0.95以上.
2.批内与批见应分别小于9%和11%
保存条件及有效期:
1.试剂盒保存;2-8℃.
2.有效期:6个月
