摘要

在两个空军设施内收集了野生动物粪便样本，以评估市售 DNA 和 RNA 提取试剂盒的有效性。使用了四种 DNA 提取试剂盒、两种 DNA/RNA 提取试剂盒和一种仅提取 RNA 的试剂盒。对样本提取物的核酸浓度、TapeStation DNA 或 RNA 完整性数值以及是否存在 PCR 抑制剂进行了评估。就 DNA 试剂盒而言，PFP 产生的浓度高于 PLM 和 RPM，而 MWFM 产生的 DNA 完整性数值高于 RPM。没有检测到 PCR 抑制剂。在 RNA 试剂盒中，RPM 的浓度高于 MWTV，但 RNA 完整性数值没有差异。在所有 RNA 样品中都发现了 PCR 抑制现象，其中 MWTV 的抑制率高于 RPM。

Comparison of commercially available DNA and RNA extraction kits for wildlife feces collected from the environment.

Wildlife fecal samples were collected across two Air Force installations to evaluate the effectiveness of commercially available DNA and RNA extraction kits. Four DNA kits, two DNA/RNA kits and one RNA only kit were used. Sample extracts were evaluated on nucleic acid concentration, TapeStation DNA or RNA Integrity Number values and presence of PCR inhibitors. For the DNA kits, PFP produced higher concentrations compared with PLM and RPM, while MWFM gave higher DNA Integrity Number values when compared with RPM. No PCR inhibition was detected. For the RNA kits, RPM gave higher concentrations compared with MWTV and no differences were seen in RNA Integrity Number values. PCR inhibition was observed in all RNA samples, with MWTV exhibiting higher inhibition compared with RPM.
