If you are interested in methanol fixation as a means for processing infectious samples, you may be interested in our page on Processing Samples Containing Infectious Agents using the 10x Genomics Chromium Controller and Protocols.
This protocol outlines methanol fixation and rehydration of single cell suspensions for use with 10x Genomics Single Cell protocols. The protocol was demonstrated with Jurkat T lymphocytes, embryonic brain cells, and human peripheral blood mononuclear cells (PMBCs). Additional optimization may be required when working with other cell types (e.g. media type, resuspension buffer, centrifugation speed, and time). Preparation of single cell suspensions directly from solid tissues or cryopreserved samples may also require additional optimization during dissociation and/or cell handling, which is not covered here.
At this time, methanol fixation of cells has only been validated for compatibility with the Single Cell Gene Expression Solution. It has not been validated with the Single Cell Immune Profiling Solution and is not supported.
