The transport of biological materials must protect samples from degradation and ensure courier safety. The main goal of this study was to evaluate the usefulness of a new type of container designed for the secured transport of biological material for storing samples for quantitative RNA analyses. This was achieved by analyzing changes in the expression of selected human leucocyte housekeeping genes (, , and ) using reverse transcription quantitative PCR (RT-qPCR) and digital PCR (RT-dPCR) techniques. Digital PCR analysis evidenced that the novel type of container retains a higher count of analyzed gene copies per µL of samples during 5 h of incubation time. The container ensures a low maintenance temperature for several hours, making it useful for sustaining the conditions for transporting biological samples. This novel container can be used to store and transport biological material to be analyzed by molecular techniques and can retain the stability of total RNA over several hours.
生物材料的运输必须保护样本不被降解,并确保快递安全。本研究的主要目的是评估一种新型容器的实用性,该容器专为生物材料的安全运输而设计,用于储存样本以进行定量RNA分析。这是通过使用逆转录定量PCR(RT-qPCR)和数字PCR(RT-dPCR)技术分析选定的人类白细胞管家基因(、和)的表达变化来实现的。数字PCR分析表明,在5小时的孵育时间内,这种新型容器每微升样本中保留的分析基因拷贝数更高。该容器可确保数小时的低温维持,使其有助于维持生物样本的运输条件。这种新型容器可用于储存和运输待通过分子技术分析的生物材料,并可在数小时内保持总RNA的稳定性。
