Unlock the potential of every specimen by enabling iterative analysis of precious samples, far beyond the original experiment.
Our proprietary technology can boost your research with 10-fold more analysis from your precious samples. The expo-Archive is a bead-based molecular archiving platform that permanently tethers full-length cDNA to expo-Beads, preserving the complete transcriptomic template for 10 or more iterative downstream assays without degrading or consuming the original source material.
Turn sample into an expo-Archive and preserve long cDNA or gDNA molecules
Copy 10 or more expo-Replicas from template for downstream sequencing assays
