Abstract

Despite powerful DNA repair systems, oxidative damage/modification to DNA is an inevitable side effect of metabolism, ionizing radiation, lifestyle habits, inflammatory pathologies such as type-2 diabetes or metabolic syndrome, cancer and natural aging.

One of the most common oxidative DNA modifications is 8-OHdG (8‑hydroxy-2′-deoxyguanosine), which is the most widely used marker in research and clinical diagnostics. 8-OHdG is easily and specifically detectable in various samples such as urine, plasma, cells and tissues via a large variety of methods like ELISA, HPLC, chromatographic methods, and immunochemistry.

Formed by oxidation of guanine and being representative for the degree of DNA damage, 8-OHdG can be also used as biomarker for risk assessment of various cancers as well as degenerative diseases.

Here, we present a highly specific, self-developed 8-OHdG antibody in successful comparison to a commercially one, tested in cells (FF95, HCT116, and HT22) and intestinal tissue, focusing on automatized evaluation via fluorescence/confocal microscopy.

使用特制抗体，通过免疫荧光自动测定细胞和组织中的 8-OHdG

尽管有强大的 DNA 修复系统，DNA 的氧化损伤/修饰仍是新陈代谢、电离辐射、生活习惯、炎症性病变（如 2 型糖尿病或代谢综合征）、癌症和自然衰老不可避免的副作用。8-OHdG（8-羟基-2′-脱氧鸟苷）是最常见的 DNA 氧化修饰之一，也是研究和临床诊断中最广泛使用的标记物。8-OHdG 可通过 ELISA、HPLC、色谱法和免疫化学等多种方法在尿液、血浆、细胞和组织等各种样本中轻松、特异地检测到。8-OHdG 由鸟嘌呤氧化形成，可代表 DNA 的损伤程度，也可用作各种癌症和退行性疾病风险评估的生物标记物。在这里，我们介绍了一种高度特异性的自主开发的 8-OHdG 抗体，并与市售抗体进行了成功对比，该抗体在细胞（FF95、HCT116 和 HT22）和肠道组织中进行了测试，重点是通过荧光/共聚焦显微镜进行自动评估。
