中文名称/Chinese Name:人β-防御素2(HBD-2)Elisa试剂盒
英文名称/English Name:Human HBD2 (Beta Defensin 2) ELISA Kit
货号/Catalog Number:E-EL-H0996
种属/Organism:Human/人
指标名称/Other Names:HBD-2
检测方法/Method:Sandwich-ELISA/双抗体夹心ELISA
检测范围/Detection Range:62.5-4000pg/mL
灵敏度/Sensitivit:37.5pg/mL
检测样品/Sample Type:Serum, Plasma, Other biological fluids/血清、血浆等其它生物样品
检测原理:
本试剂盒采用双抗体夹心ELISA法。用抗人HBD-2抗体包被于酶标板上,实验时标本或标准品中的HBD-2会与包被抗体结合,游离的成分被洗去。依次加入生物素化的抗人HBD-2抗体和辣根过氧化物酶标记的亲和素。抗人HBD-2抗体与结合在包被抗体上的人HBD-2结合、生物素与亲和素特异性结合而形成免疫复合物,游离的成分被洗去。加入显色底物,TMB在辣根过氧化物酶的催化下现蓝色,加终止液后变黄。用酶标仪在450nm波长处测OD值,HBD-2浓度与OD450值之间呈正比,通过绘制标准曲线求出标本中HBD-2的浓度。
标本收集:
血清:全血标本于室温放置2小时或4℃过夜后于1000×g离心20分钟,取上清即可检测,收集血液的试管应为一次性的无热原,无内毒素试管。血浆:抗凝剂推荐使用EDTA,标本采集后30分钟内于1000×g离心15分钟,取上清即可检测。避免使用溶血,高血脂标本。其它生物标本:1000×g离心20分钟,取上清即可检测标本应清澈透明,悬浮物应离心去除。标本收集后若不及时检测,请按一次使用量分装,冻存于-20℃/-80℃电冰箱内,避免反复冻融,6个月内进行检测,4℃保存的应在1周内进行检测。 如果样本中检测物浓度高于标准品最高值,请根据实际情况,做适当倍数稀释(建议先做预实验,以确定稀释倍数)。
试验所需自备物品:
酶标仪(450nm波长滤光片)高精度移液器,EP管及一次性吸头:0.5-10μL, 2-20μL, 20-200μL,200-1000μL37℃恒温箱, 双蒸水或去离子水
