​牛(Bovine)3-羟酰辅酶A脱氢酶(3-HCD)ELISA检测试剂盒

牛(Bovine)3-羟酰辅酶A脱氢酶(3-HCD)ELISA检测试剂盒 产品货号:DM-Cat9873产品规格:48/96TELISA(酶联免疫吸附测定,Enzyme-Linked Immunosorbent Assay)的核心原理是:抗原与抗体的特异性免疫反应 + 酶催化底物的化学显色反应,通过颜色深浅定量 / 定性判断样本中待测物浓度。一、核心逻辑(所有 ELISA 都遵循)1. 免疫识别:利用抗原(Ag)和抗体(Ab)之间高度特异性结合,只 “抓” 目标分子。2. 酶标记放大:将酶(常用 HRP、AP)标记在抗体 / 抗原上,作为信号放大系统。3. 底物显色:酶催化无色底物生成有色产物,颜色深浅与酶量成正比,也与待测物浓度成正比。4. 比色定量:酶标仪测吸光度(OD 值),通过标准曲线计算待测物浓度。二、四大经典 ELISA 检测原理(*常用)1. 双抗体夹心法(Sandwich ELISA)—— *常用,测大分子抗原 / 蛋白适用对象:大分子蛋白、细胞因子、激素、膜蛋白、分泌蛋白等(有多个抗原表位)。结构:捕获抗体 → 待测抗原 → 检测抗体(酶标 / 生物素化)。步骤逻辑:1. 固相载体(微孔板)预包被捕获抗体(Capture Ab)。2. 加入样本,样本中的待测抗原(Ag)与捕获抗体特异性结合。3. 加入酶标记检测抗体(Detection Ab-HRP),与抗原另一表位结合,形成:捕获 Ab - 抗原 Ag - 检测 Ab-HRP 夹心复合物。4. 洗去未结合物质,加入底物 TMB,HRP 催化显色。5. 加终止液,测 OD 值。颜色越深 → 抗原浓度越高。特点:特异性高、灵敏度高(pg/mL 级)。适合大分子、多表位抗原。不适合小分子(如激素、药物小分子,表位太少夹不住)。 2. 直接法 ELISA(Direct ELISA)—— *简单,测抗原适用对象:已知抗原定性 / 半定量,或包被抗原的验证。结构:固相抗原 → 酶标一抗。步骤逻辑:1. 微孔板直接包被待测抗原(Ag)。2. 加入酶标记一抗(Primary Ab-HRP),直接与抗原结合。3. 洗板、加底物显色、测 OD。4. 颜色越深 → 抗原量越多。特点:步骤*少、速度快。但灵敏度低,一抗需酶标记,通用性差。科研中多用于包被效率验证,少用于临床 / 精确定量。 3. 间接法 ELISA(Indirect ELISA)—— 主要测抗体(如抗体滴度、自身抗体)适用对象:检测样本中的抗体(如 IgG、IgM、病毒抗体、自身抗体)。结构:固相抗原 → 一抗(样本抗体) → 酶标二抗。步骤逻辑:1. 微孔板包被已知纯化抗原(Ag)。2. 加入样本,样本中的 ** 待测抗体(Ab)** 与抗原结合。3. 加入酶标记二抗(Secondary Ab-HRP,抗人 / 抗鼠 IgG 等),识别一抗 Fc 段。4. 洗板、显色、测 OD。颜色越深 → 样本中抗体滴度越高。特点:灵敏度高,二抗可通用(同一酶标二抗可测多种一抗)。主要用于抗体检测,不适合测抗原。 4. 竞争法 ELISA(Competitive ELISA)—— 测小分子抗原 / 半抗原适用对象:小分子激素、药物、多肽、毒素、小分子代谢物(只有一个表位,无法夹心)。结构:固相抗体 / 抗原 + 酶标抗原 / 抗体与样本待测物 “竞争结合”。有两种常见形式,原理一致、方向相反:(1)抗体包被,酶标抗原竞争(*常用)1. 微孔板包被捕获抗体。2. 同时加入:样本待测小分子抗原 + 酶标记抗原(Ag-HRP)。3. 两者竞争结合有限的抗体位点:4. 样本中抗原多 → 占据更多抗体 → 酶标抗原结合少 → 显色浅。5. 样本中抗原少 → 酶标抗原结合多 → 显色深。6. 显色后,OD 值与待测抗原浓度成反比。(2)抗原包被,酶标抗体竞争1. 微孔板包被已知抗原。2. 样本待测抗原 + 酶标抗体混合加入,竞争结合抗原。3. 样本抗原多 → 酶标抗体结合少 → 显色浅。特点:必须用于小分子、单表位物质。标准曲线是下降型(浓度越高,OD 越低),计算时注意方向。特异性要求极高,否则易受结构类似物干扰。 三、信号系统原理(HRP + TMB *常见)绝大多数 ELISA 用这套:1.酶:辣根过氧化物酶(HRP)。2.底物:TMB(四甲基联苯胺),无色。3.反应:HRP 催化 H₂O₂氧化 TMB → 生成蓝色可溶性产物。4.终止:加硫酸(终止液),蓝色变为黄色,稳定。5.读数:450 nm 测 OD(参考波长 630 nm)。方法主要检测对象信息与浓度关系适用分子大小典型应用双抗体夹心法抗原(蛋白)正相关(浓度高→色深)大分子(多表位)小分子、半抗原直接法抗原正相关大分子抗原定性、包被验证间接法抗体正相关抗体病毒抗体、自身抗体、免疫滴度竞争法抗原(小分子)负相关(浓度高→色浅)小分子、半抗原类固醇激素、药物、多肽、毒素一句话总结双抗体夹心法:捕获抗体抓抗原,酶标抗体再夹心,色深 = 浓度高。间接法:抗原抓样本抗体,酶标二抗放大,色深 = 抗体高。竞争法:样本与酶标物抢结合位点,色浅 = 浓度高。 试剂盒的组成结果判断一、显色与 OD 值初判(肉眼 + 酶标仪)显色观察:标准品孔应呈梯度显色(TMB 底物终止后由蓝变黄);空白 / 阴性对照基本无色。 OD 值质控(夹心法常用):空白孔 OD < 0.2 *高标准品 OD > 1.0 样本 OD 需落在标准曲线范围内;超出上限→稀释重测;低于下限→浓缩或换高敏试剂盒 二、标准曲线与对照验证(实验有效性)标准曲线:相关系数 R² ≥ 0.99(越接近 1 越好) 推荐用 四参数逻辑(4PL)拟合 标准品 CV% < 8% 对照孔:阴性对照(NC):背景低,过高提示非特异结合 阳性对照(PC):应有明显信号,无信号则实验失败 样本重复性:复孔 CV% < 10%(可靠);10%–15% 可接受;>15% 需重测 三、结果判读方法1. 定性判断(阴 / 阳)计算 Cut-off 值(按试剂盒说明书,常见:NC 均值 + 2SD 或 NC×2.1) 样本 OD > Cut-off → 阳性 样本 OD < Cut-off → 阴性 接近 Cut-off → 复测确认 2. 定量判断(浓度计算)用标准曲线将样本 OD 值换算为目标物浓度 结果需在试剂盒检测范围内 3. 半定量判断(效价 / 相对水平)以*高稀释倍数仍呈阳性为效价,用于抗体滴度等 四、常见异常与处理高背景 / 花板:优化封闭、洗涤,降低抗体浓度 无显色 / 显色过浅:检查底物、抗体活性,延长孵育 曲线 R² 低 / 点偏离:排查移液、标准品稀释、孵育条件 复孔 CV 大:规范加样、洗板,减少边缘效应

​牛(Bovine)牛磺去氧胆酸(TDCA)ELISA检测试剂盒

牛(Bovine)牛磺去氧胆酸(TDCA)ELISA检测试剂盒产品货号:DM-Cat6971产品规格:48/96TELISA 检测试剂盒的检测原理ELISA 全称酶联免疫吸附测定(Enzyme-Linked Immunosorbent Assay),是目前生物检测领域应用*广泛的免疫分析技术,该试剂盒仅用于科研检测。其核心总原理是:基于抗原与抗体的特异性免疫识别结合反应,耦合酶对底物的高效催化信号放大效应,将免疫结合的特异性信号转化为可通过酶标仪定量检测的显色 / 光信号;通过固相吸附与洗涤步骤实现结合态与游离态物质的彻底分离,*终实现对待测物(抗原或抗体)的高特异性、高灵敏度定性与定量检测。一、ELISA 试剂盒的核心基础元件与作用所有 ELISA 试剂盒均围绕四大核心元件构建,是实现检测的基础:固相载体:主流为 96 孔 / 384 孔聚苯乙烯酶标板,可通过疏水作用稳定吸附蛋白类抗原 / 抗体,且不破坏其免疫活性,为免疫反应提供固定的固相界面。免疫核心试剂:包被用捕获抗原 / 抗体、酶标记的检测抗原 / 抗体(酶标结合物)。基于抗原表位与抗体互补决定区(CDR)的特异性结合,是保证检测特异性的核心,可*大程度避免交叉反应。酶 - 底物信号系统:*常用辣根过氧化物酶(HRP)、碱性磷酸酶(AP)。酶分子具备极高的催化效率,一个酶分子可在短时间内催化大量底物分子生成有色产物,实现检测信号的级联放大,让 ELISA 可检测 pg/mL 甚至 fg/mL 级别的微量待测物;产物的吸光度(OD 值)与待测物含量存在明确的剂量 - 效应关系,是定量检测的核心依据。封闭与洗涤体系:封闭液(如 BSA、脱脂奶粉)用于覆盖酶标板上未吸附蛋白的空白位点,阻断非特异性结合,降低背景干扰;洗涤液用于彻底分离固相结合的免疫复合物与游离的未结合物质,去除样本杂质和多余试剂,保障检测结果的准确性。二、主流 ELISA 试剂盒的分型检测原理根据检测靶标、分子大小与应用场景的不同,商品化 ELISA 试剂盒主要分为以下 5 种经典类型,其中双抗体夹心法、竞争法、间接法为市场主流。1. 双抗体夹心法(大分子抗原检测**,*主流)核心适用场景:检测具有至少 2 个独立抗原表位的大分子物质,如细胞因子(IL-6、TNF-α 等)、蛋白类肿瘤标志物、病原微生物结构蛋白、抗体药物等。核心原理步骤:包被固化:将针对待测抗原的特异性捕获抗体固定于酶标板孔内,洗涤去除未结合的多余抗体,封闭空白位点。抗原捕获:加入待测样本 / 标准品,样本中的待测抗原与固相捕获抗体特异性结合,形成 “捕获抗体 - 待测抗原” 复合物,洗涤去除未结合的样本杂质。夹心结合:加入针对待测抗原另一独立表位的酶标记检测抗体,与复合物中的抗原结合,形成 “捕获抗体 - 待测抗原 - 酶标检测抗体” 的双抗体夹心结构,洗涤去除未结合的酶标抗体。显色定量:加入酶对应底物,酶催化底物发生显色反应;终止反应后,通过酶标仪测定 OD 值。显色深浅(OD 值)与样本中待测抗原的含量呈正相关,通过标准品绘制的浓度 - OD 值标准曲线,即可计算出样本中待测抗原的**浓度。2. 竞争法(小分子抗原 / 半抗原检测核心方案)核心适用场景:检测仅含单个抗原表位的小分子半抗原,如激素、农药、兽药、真菌毒素、药物残留、毒品代谢物等,也可用于部分抗体的定量检测。核心原理(抗原包被型,商品化试剂盒*常用):包被固化:将待测抗原(或抗原 - 载体偶联物)固定于酶标板孔内,洗涤去除多余包被物,封闭空白位点。竞争性结合:同时加入待测样本与固定剂量的酶标抗体,样本中游离的待测抗原,与固相板上包被的抗原,竞争性结合酶标抗体的有限结合位点。竞争逻辑:样本中待测抗原含量越高,能与固相包被抗原结合的酶标抗体就越少;反之,待测抗原含量越低,结合到固相上的酶标抗体就越多。显色定量:洗涤去除未结合的游离物质后,加入底物显色。OD 值与样本中待测抗原的含量呈负相关,通过标准曲线完成定量检测。3. 间接法(抗体检测金标准方案)核心适用场景:检测样本中的特异性抗体,如病原体感染抗体(乙肝、新冠病毒抗体)、自身免疫抗体、疫苗免疫后的抗体滴度检测、过敏原特异性抗体检测等。核心原理步骤:包被固化:将与待测抗体对应的特异性抗原固定于酶标板孔内,洗涤去除多余抗原,封闭空白位点。一抗结合:加入待测样本,样本中针对包被抗原的特异性抗体(一抗,即待测抗体)与固相抗原特异性结合,形成 “包被抗原 - 待测抗体” 复合物,洗涤去除未结合的杂蛋白与非特异性抗体。二抗结合:加入酶标记的抗种属抗体(二抗,如酶标抗人 IgG 抗体),与复合物中的待测抗体结合,洗涤去除未结合的酶标二抗。显色判定:加入底物显色,OD 值与样本中待测抗体的含量呈正相关,既可通过临界值判定阴阳性(定性),也可通过梯度稀释实现抗体滴度的定量检测。4. 抗体捕获法(IgM 抗体早期感染检测专用)核心适用场景:病原体急性感染的早期 IgM 抗体检测,如急性甲肝、新冠早期感染、优生优育 TORCH IgM 检测等,可有效排除样本中 IgG 抗体的干扰,避免假阳性。核心原理步骤:包被:将抗人 IgM 抗体固定于酶标板孔内,洗涤封闭后,加入待测样本,捕获样本中所有的 IgM 抗体(包括待测特异性 IgM 和非特异性 IgM)。抗原结合:洗涤后加入特异性抗原,仅与捕获到的待测特异性 IgM 结合。酶标检测:加入酶标记的针对该抗原的特异性抗体,与抗原结合,再次洗涤后加入底物显色,OD 值与样本中待测特异性 IgM 抗体含量正相关。5. 直接法(基础原型,极少单独用于商品化试剂盒)核心原理:将抗原包被于固相板,封闭后直接加入酶标记的特异性抗体,抗原抗体结合后洗涤、显色,OD 值与结合的酶标抗体量正相关。特点:操作简单、步骤少、实验周期短;但需为每种检测抗体制备专属酶标物,通用性差、成本高,且非特异性干扰强,仅适用于目标抗原含量较高的快速定性筛查、抗体特异性验证。方法主要检测对象信息与浓度关系适用分子大小典型应用双抗体夹心法抗原(蛋白)正相关(浓度高→色深)大分子(多表位)小分子、半抗原直接法抗原正相关大分子抗原定性、包被验证间接法抗体正相关抗体病毒抗体、自身抗体、免疫滴度竞争法抗原(小分子)负相关(浓度高→色浅)小分子、半抗原类固醇激素、药物、多肽、毒素三、ELISA 技术的核心核心优势原理高特异性:基于抗原 - 抗体的免疫识别反应,仅针对靶标分子的特定表位结合,可*大程度规避样本中其他物质的交叉干扰。超高灵敏度:酶的级联催化放大效应,可将微量的免疫结合信号放大百万倍,实现常规方法无法检测的超微量物质定量。宽线性定量范围:通过标准品梯度稀释构建标准曲线,可实现多个数量级范围内的**定量,适配不同浓度样本的检测需求。操作标准化、通量高:96 孔板体系可实现批量样本同步检测,操作流程标准化,适配自动化设备,适合临床与大规模筛查场景。四、试剂盒的组成五、样本处理1. 血清样本:采集静脉血后,室温静置2-4小时,3000rpm离心10分钟,收集上层血清,避免溶血,-20℃或-80℃保存,避免反复冻融。2. 血浆样本:使用抗凝管(EDTA、肝素等)采集血液,采集后立即轻轻颠倒混匀,3000rpm离心10分钟,收集上层血浆,-20℃或-80℃保存。3. 组织培养上清:细胞培养完成后,3000rpm离心5分钟,去除细胞碎片,收集上清液,-20℃保存。4. 细胞/组织裂解液:取适量细胞或组织样本,加入预冷的裂解液,冰浴匀浆后,4℃、12000rpm离心15分钟,收集上清液,-80℃保存。5. 所有样本在检测前需恢复至室温,震荡混匀,若有沉淀需再次离心去除,避免影响检测结果。根据样本实际情况,可使用样本稀释液进行适当稀释,确保检测浓度落在标准曲线范围内。六、实验步骤1. 试剂准备:实验前将所有试剂盒组分及样本恢复至室温(25℃左右),浓缩洗涤液用蒸馏水稀释至1×工作液,浓缩检测抗体、链霉亲和素-HRP按说明书比例用样本稀释液稀释至工作液,现配现用。2. 加样:根据实验需求确定所需板条数量,空白孔加入50μL样本稀释液,标准品孔加入50μL不同浓度的标准品工作液,待测样本孔加入50μL处理后的样本(已稀释的样本直接加入,未稀释样本可根据情况用样本稀释液1:1稀释后加入);随后向所有孔中加入50μL生物素标记检测抗体工作液,轻轻振荡混匀。3. 孵育:盖上封板膜,置于37℃恒温箱中孵育60分钟。4. 洗涤:小心揭开封板膜,甩去孔内液体,每孔加满1×洗涤液,静置30秒后甩去,用吸水纸拍干;重复此洗涤步骤3次,若使用洗板机,洗涤次数可增加1次。5. 加酶:每孔加入80μL链霉亲和素-HRP工作液,轻轻振荡混匀,盖上封板膜,37℃孵育30分钟。6. 洗涤:重复步骤4的洗涤操作,彻底去除未结合的酶结合物。7. 显色:每孔依次加入50μL显色液A和50μL显色液B,轻轻振荡混匀,盖上封板膜,37℃避光孵育10分钟,此时阳性孔会逐渐呈现蓝色。8. 终止:取出酶标板,迅速向每孔加入50μL终止液,轻轻振荡混匀,蓝色会立即转为黄色。9. 检测:加入终止液后10分钟内,使用酶标仪在450nm波长处测定各孔的OD值(若需校正,可在630nm波长处测定参考OD值,*终检测OD值=450nm OD值-630nm OD值)。七、结果计算1. 首先计算每个标准品、空白孔及样本孔的平均OD值(复孔检测时),空白孔OD值作为阴性对照,用于扣除背景干扰。2. 以标准品浓度为横坐标(X轴,对数坐标),对应的OD值为纵坐标(Y轴,线性坐标),使用专业绘图软件(如Excel、GraphPad Prism)绘制标准曲线,计算回归方程(R²值应≥0.99,确保标准曲线的可靠性)。3. 将扣除背景后的样本OD值代入回归方程,计算出样本中[检测指标]的初步浓度,再根据样本的稀释倍数计算出样本的实际浓度。(仅供参考)八、试剂盒性能1. 准确性:标准品线性回归与预期浓度相关系数R值,大于等于0.9900。2. 灵敏度:*低检测浓度如资料所示。3. 特异性:不与其它可溶性结构类似物交叉反应。4. 重复性:板内、板间变异系数均小于15%。5. 贮藏:2-8℃,避光防潮保存。6. 有效期:6个月九、储存与运输1. 试剂盒未开封时,所有组分需密封置于2~8℃冷藏保存,避免冷冻,其中标准品冻干品可置于-20℃长期保存。2. 试剂盒开封后,预包被酶标板需密封防潮保存,剩余试剂需按原储存条件保存,避免反复冻融,开封后建议在1个月内用完。3. 运输过程采用冷链运输(2~8℃),避免高温、剧烈震荡,确保产品性能稳定。十、注意事项实验前请仔细阅读本说明书,严格按照实验步骤操作,确保实验条件(温度、孵育时间)符合要求。所有试剂使用前需充分混匀,但避免剧烈震荡产生大量泡沫,以免影响加样精度。洗涤步骤至关重要,需确保洗涤充分,避免未结合的杂蛋白或酶结合物残留,导致背景值偏高。显色反应需避光进行,终止液加入后应立即检测OD值,避免放置时间过长导致颜色消退,影响检测结果。实验所用样本、试剂及废弃物均需按生物安全规范处理,避免交叉污染。本试剂盒仅用于科研用途,不用于临床诊断。十一、售后服务东升国际-创意平台-注册畅享文化之梦! 拥有专业的技术服务团队,为您提供全程技术支持。如您在产品使用过程中有任何疑问,或对产品质量有异议,请及时联系东升国际 的技术顾问,东升国际 将在24小时内响应,为您提供实验方案优化、问题排查等专业服务。联系电话:400-9681786 官网:jbvoptical.com 邮箱:dm_support@sina.com生产厂家:东升国际-创意平台-注册畅享文化之梦!
