Optimized tissue sample storage for genomic analysis

Tissue sample storage is necessary when you need to collect and store samples until ready for further processing or shipping to collaboration sites. Especially for genomic analyses, ensuring the right conditions for tissue sample storage are key to avoid changes in cellular composition and minimize cellular stress responses that could negatively impact downstream analyses. The MACS Tissue Storage Solution ensures to uphold tissue quality and integrity to get reliable genomic results in next generation sequencing and single-cell sequencing.

Gene expression analysis of stress-related genes
Gene expression analysis of stress-related genes in stored tumors compared to fresh tumors shows no changes in expression levels

Prevention of cellular stress responses after short-term storage of mouse tumors

After 48 hours of storage in MACS Tissue Storage Solution, mouse tumors showed minimal changes in cellular stress-related gene expression as compared to fresh tumors. This is an advantage to increasing work-time flexibility in a genomics lab and for reliable downstream gene expression analyses.

Tissue sample storage in MACS Tissue Storage Solution enables flexibility in sample processing by allowing the optimal storage of solid tissues for at most 48 h at 2–8°C. It has been validated with a variety of human and murine tissues including tumor, lung, spleen, brain, or skeletal muscle.
