Description

有机速干封片剂
技术领域
本发明属于生物医药应用技术领域,尤其涉及一种有机速干封片剂。
背景技术
封片是将组织切片(亦可是血液涂片、细胞爬片等)封固保存于载玻片与盖玻片之间,使之不与空气发生接触,防止其氧化、褪色,利于镜检观察及保存。对于组织切片,完成染色后经过脱水透明后,为了易于在显微镜下观察,并能长时间保存备查,需要用封片剂(又称封固剂、封片介质等)把染片封固起来,从而完成一张组织玻片标本的制作。一般情况下,较好的封片剂具有如下特点:1、牢固的黏性;2、较好的折光性;3、折光率与玻片差距不大;4、能与透明剂相混合;5、中性,对染料无影响等。
目前,市面上常用的封片剂有两大类:1、非水溶性胶:主要用于染色后经无水乙醇脱水,二甲苯透明的染色片的封片。常用的有中性树胶、加拿大树胶、DPX合成树脂等。2、水溶性胶:主要用于染色后不能经无水乙醇脱水,二甲苯透明的染色片的封固。常用的水溶性胶有甘油明胶、阿拉伯糖胶以及进口的专用水溶性胶等。
现有的传统组织切片封片剂存在很多缺点:将载玻片与盖玻片干燥及粘贴牢固需要时间长,大约需要1个月;胶体颜色淡黄略浑浊,折光性与透亮度稍差;传统的封片剂的固体溶质呈酸性,在制备的过程中必须进行中性化处理,容易导致产品的酸碱度波动,进而引起组织切片在保存的过程中染色后容易褪色的现象,不利于切片品质的长期保持。上述问题,亟待解决。
发明内容
本发明针对现有技术中的不足,提供了一种有机速干封片剂,干燥时间快,粘贴牢固,且胶体无色透明,折光性能好。
为了解决上述技术问题,本发明通过下述技术方案得以解决:有机速干封片剂,所述封片剂包括如下组分:50%-80%体积比的二甲苯,5%-30%体积比的甲苯,20%-30%体积比的聚甲基丙烯酸异丁酯。
为了取得更好的技术效果,进一步的技术改进还包括,所述二甲苯体积比为60%,所述甲苯体积比为18.5%,所述聚甲基丙烯酸异丁酯体积比为21.5%。
有机速干封片剂的制备方法包括如下步骤:取适量的二甲苯,甲苯和聚甲基丙烯酸异丁酯按比例加入密封容器,混匀至甲基丙烯酸异丁酯完全溶解,成品分装保,即获得有机速干封片剂。
本发明的有益效果是:1、本发明有机速干封片剂能够有效缩短切片干燥时间,封片后3天完全干燥,盖玻片粘贴牢固;
2、本发明有机速干封片剂的胶体无色透明,折光性能明显优于传统封片剂;
3、本发明有机速干封片剂使用的胶体溶剂成分为有机聚合丙烯酸大分子,PH值为中性,不电离,封片后对切片中的染料分子不发生反应,可以长时间有效保存组织切片的颜色。
具体实施方式
下面结合具体实施方式对本发明作进一步详细描述。
实施例1:本发明有机速干封片剂的第一种具体实施例。有机速干封片剂,所述封片剂包括如下组分:60%体积比的二甲苯,18.5%体积比的甲苯,21.5%体积比的聚甲基丙烯酸异丁酯。
有机速干封片剂的制备方法包括如下步骤:取适量的二甲苯,甲苯和聚甲基丙烯酸异丁酯按比例加入密封容器,混匀至甲基丙烯酸异丁酯完全溶解,成品分装保存,即获得有机速干封片剂。
本发明的有机速干封片剂能够有效缩短切片干燥时间,封片后3天完全干燥,盖玻片粘贴牢固。有机速干封片剂(实施例1)与中性树胶封片各封片100片干燥时间对比实验:
本发明的有机速干封片剂的折光性能明显优于传统封片剂,本发明中的有机速干封片剂中的组份都为中性组份,化学性质稳定,不含有生色基团,因此长时间保存后颜色、折光性也不会发生变化;而传统的封片胶体中,出于成本考虑或工艺难度等问题,纯度不高,含有少量的生色基团、活性集团,因此颜色普遍淡黄略浑浊,折光性与透亮度稍差,且久置后颜色加深更加明显。
本发明的有机速干封片剂的PH值为中性,不电离,封片后对切片中的染料分子不 发生反应,可以长时间有效保存组织切片的颜色。有机速干封片剂(实施例1)与中性树胶封 片各封片100片,组织切片颜色褪色对比实验:
出现褪色的切片数(封片后3个月) 出现褪色的切片数(封片后6个月) 出现褪色的切片数(封片后12个月) 出现褪色的切片数(封片后24个月)
