Description
技术领域
本发明涉及联检试剂盒技术领域,特别是涉及一种用于肠息肉因子检测的联检试剂盒及其制备方法、检测方法和应用。
背景技术
结肠直肠癌是起源于大肠上皮的癌症,是常见的恶性肿瘤。早期症状多以排便习惯和粪便性状改变为主,容易被忽视;晚期可出现腹痛、腹部肿块、进行性消瘦等症状。早发现、早诊断、早治疗是治疗的关键,主要以做肠镜和手术切除治疗为主。
90%的结直肠癌由结直肠息肉演变而来,它是一种癌前病变,出现息肉后的4-5年时间内,息肉会逐渐恶变为癌症。因此全面了解息肉并提早切除,能有效降低结直肠癌的发生。息肉是指人体组织表面长出的多余肿物,现代医学通常把生长在人体黏膜表面上的赘生物统称为息肉。大肠息肉是指高出肠黏膜的局部隆起性病变,其经常呈多发分布,平时隐蔽生长,然后不典型增生后成为结肠癌。“息肉-不典型增生-癌”的演变过程大概要经过10~15年,这一宝贵的时间窗为结直肠癌的预防和早诊早治提供了机会。目前肠镜是唯一检查肠息肉的方法,但需要去医院进行,且需要专业化人员操作专业化仪器,结果检出时间长。
发明内容
本发明的目的是针对现有技术中存在肠息肉检测繁复,检出结果所需时间,而提供一种用于肠息肉因子检测的联检试剂盒。

具体实施方式
以下结合具体实施例对本发明作进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
实施例1
一种用于肠息肉检测的联检试剂盒,包括具有分别检测以下指标的九个如图1所示的试纸条:M2-丙酮酸激酶(M2-PK)、基质金属蛋白酶9(MMP-9)、髓过氧化物酶(MPO)、谷胱甘肽S-转移酶Pi(GST-Pi)、胞苷脱氨酶(CDA)、视黄醇结合蛋白4(RBP4)、丝氨酸蛋白酶抑制剂F2(SERPIN-F2)、钙卫蛋白(CAL)和大便隐血(FOBT);
每个试剂条的连接垫2上均包被有检测抗体-胶体金结合物,所述试剂条的检测线3上包被有特异性捕获抗体,每一个试纸条上的特异性捕获抗体均不相同。
具体的,所述试纸条包括依次搭接在背衬7上的样品垫1、连接垫2(本实施例中采用聚酯材料)、检测垫5(本实施例中采用硝酸纤维素膜)以及吸收垫6。所述检测垫5上设置有检测线3(T线)和质检线4(C线),所述质检线4预包被羊抗鼠IgG抗体。
所述联检试剂盒还包括样品处理试剂,所述样品处理试剂包括Tris、一水合柠檬酸、氯化钙、BSA和Proclin300,所述样品处理方法为:将样品置于盛有样品处理试剂的试管中后密闭试管摇晃混匀。所述试管采用专利2020201791735公开的粪便定量取样器
所述联检试剂盒的试纸上包被物及其检出限如表1所示。
表1 特异性捕获抗体包被量及检出限
本发明的联检试剂盒是利用胶体金免疫层析技术和夹心免疫法的原理研制而成的。试纸的硝酸纤维素膜上的检测线3已包被特异性捕获抗体,质检线4包被了羊抗鼠IgG抗体,聚酯膜上预包被了胶体金标记的特异性检测抗体。检测时样本沿着试纸条向上爬行溶解聚酯膜上的检测抗体-胶体金结合物,如样本中存在肠息肉因子,则肠息肉因子与检测抗体-胶体金结合物结合形成Ag-Ab-胶体金结合物,该结合物继续爬行到硝酸纤维素膜上与检测线3预包被的特异性捕获抗体特异性集合,形成Ab-Ag-Ab-胶体金,并堆积显色成一条明显的微红色的条带即T线,这代表阳性结果。如果样本中不含有肠息肉因子,则在检测线3位置不会形成明显的红色条带,这代表阴性结果。游离的检测抗体-胶体金继续向试纸上方爬行到质检线4与预包被的羊抗鼠IgG抗体结合,并堆积显色,形成一条微红色的条带,这代表质检线4即C线。
实施例2
一种基于所述联检试剂盒的检测方法,包括以下步骤:
步骤S1,样品采集及后处理,如图2所示:
步骤S1.1,从试剂盒拿出样品裂解液;
步骤S1.2,收集粪便前,按照采样垫的使用要求,将试剂盒提供的采样垫正确安装到马桶上;
步骤S1.3,将粪便排泄于采样垫上;
步骤S1.4,旋开样本裂解液管的盖子,取出取样棒;
步骤S1.5,把取样棒直接刺入排泄物中,旋转后抽出。在样本中5个不同的位置重复上述操作,直到凹槽被样本填满;
步骤S1.6,将取样棒插入样本裂解液管内,拧紧盖子,手握该样本管上下颠倒摇晃10次,使粪便溶解于液体中,待检。
步骤S2,将步骤1后处理后的样品8分别滴加于所述联检试剂盒的九个试纸条的样品垫1上的加样孔中,等待15min。等待九项指标的结果;
步骤S3,观察并记录结果,九项指标中至少两项阳性即为肠息肉阳性。
实施例3
采用实施例2的检测方法对人体样本进行检测,样本数量268份,检测结果如表2所示,线性相关性计算的方法为:对两种试剂的测定结果作散点图,以对比试剂测定值为X轴,考核试剂测定值为Y轴,用Medcalc统计软件对两种试剂测定值进行线性相关分析,得到回归方程为y,相关系数r,95%的置信区间。
表2本发明的联检试剂盒检测和大便隐血项检测统计计算结果
由表2数据可知,本发明的联检试剂检测和FOB项单检测的结果对比说明本发明的联检结果提高了对肠息肉检测的灵敏度和特异性,进而对肠息肉导致的结肠直肠癌的检测和诊断提高了精准度。
以上所述仅是本发明的优选实施方式,应当指出的是,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
