About this study

The study aims to assess the effectiveness of various commercial and non-hazardous buffers for the storage of human gut fecal samples over time. This evaluation will be conducted by comparing the performance of these buffers against directly frozen samples using metaproteomic analysis. The study is motivated by the need for standardized protocols for sample preservation in metaproteomic research, particularly focusing on protein preservation in fecal samples. By investigating proteomic, taxonomic, and functional identifications, the research seeks to provide insights into the reliability of these buffers as storage solutions. Additionally, the study plans to explore inter- and intra-individual variabilities at the proteome level by periodically collecting fecal samples from volunteers, complementing existing knowledge in metaproteomics. Overall, the study addresses a critical gap in the field and has the potential to enhance reproducibility and comparability across metaproteomic studies
