The Gene Expression Center is now able to offer the Fixed RNA Profiling Assay from 10x Genomics. The workflow for this assay allows you to fix tissue or cells, preserving your samples for up to three months before sending them through the assay pipeline for single cell RNA sequencing. With built-in multiplexing potential, this new assay is a great way to work with fragile cells or to take some of the financial risk out of your time course studies. The Fixed RNA Profiling Assay is currently only compatible with human samples, but will soon be compatible for mouse studies as well.
