The aim of this study was to assess the DNA preservation capability of cellulose paper towel and blotting paper as low-cost alternatives to commercial DNA preservation products. Chicken blood was applied as DNA source to each paper towel, blotting paper, FTA^® cards and DNA/RNA Shield™. All samples were stored at room temperature for 130 days. DNA extraction from dried blood spots was performed after various time periods using Tris-EDTA and NaOH protocols. PCR activity and the mean amount of DNA isolated from paper towels were reliable. The results of this study demonstrated that cellulose-based blotting paper and especially paper towel had considerable DNA binding and preservation capacity for at least 130 days at room temperature without DNA degradation.

一种实用、低成本、短期的基因组 DNA 存储方法。

本研究的目的是评估纤维素纸巾和吸墨纸作为商业 DNA 保存产品的低成本替代品的 DNA 保存能力。将鸡血作为 DNA 来源应用于每张纸巾、吸墨纸、FTA ^®卡片和 DNA/RNA Shield™。所有样品均在室温下储存 130 天。在不同时间段后使用 Tris-EDTA 和 NaOH 方案从干血斑中提取 DNA。PCR 活性和从纸巾中分离的平均 DNA 量是可靠的。这项研究的结果表明，基于纤维素的吸墨纸，尤其是纸巾，在室温下至少可以保持 130 天的 DNA 结合和保存能力，而且 DNA 不会降解。
