空间生物学

细胞生物学是对生物组织的检查,以观察细胞的微观细节。在其空间背景下观察组织生物标志物和细胞表型,对于理解细胞至关重要。 细胞类型、细胞边界、相邻或相互作用的细胞、生态位和组织环境的高清空间表示对于诊断是有帮助的。传统上,诊断依赖于显微细胞形态学和免疫组织化学技术。 在过去的十年中,出现了一种新的分子诊断方法,将重点放在绘制 RNA 转录本上,不仅要了解潜在的转录组学,还要了解细胞与其在组织中的相对位置关系。 这种在生物组织的空间背景下进行组学分析的研究通常被称为空间生物学,是诊断学的下一个前沿应用。

使用两种类型的基于荧光的成像应用来描绘组织中的细胞。 这些包括蛋白质表位的 RNA 成像和迭代荧光成像。对于 RNA 成像,单分子原位杂交(smFISH)技术的变化产生了多种多样的方法,以允许在组织中的单个细胞中同时成像 10 至 1000 种 RNA。 多重误差稳健 FISH(MERFISH)允许通过误差稳健条形码、组合标记和序列成像,以高检测效率在转录组规模上对 RNA 物种进行成像和分析。 SeqFISH 使用基于颜色的条形码和顺序成像来实现相同的目标。诸如 CODEX(表达的 CO 检测)的连续荧光成像方法,该方法也允许多路复用在空间上检测数十至数百种细胞蛋白。

为了使这些技术在生物研究和未来诊断中获得商业成功, 一个具有一致性能的强大高通量荧光成像系统是前提。IDEX Health & Science 的生命科学光学部门专门设计和制造从光源到探测器的成像系统, 该系统结合了多波长平顶宽场照明,与宽视场衍射受限的高 NA 光学器件,和探测器匹配,提高了空间分辨率和吞吐量。结合我们的 Semrock® 品牌的滤光片,我们的从光源到探测器的成像系统是您优化价格和性能的选择。
