Question: What is the maximum number of cells that can be profiled?
Answer: In each 10x Single Cell Gene Expression, Immune Profiling, ATAC, or Multiome library, it is possible to target up to 10,000 cells. Each chip can process eight libraries in parallel, allowing users to target up to 80,000 cells per chip.
An important consideration when deciding how many cells to target is the cell multiplet rate. As more cells are loaded on the 10x chip, it becomes more likely that two or more cells will be partitioned together into the same GEM (cell multiplet). Please refer to the Multiplet Rate Table provided in the User Guide for each product, as shown here for the Single Cell 3' Gene Expression v3.1 assay:
You can control the multiplet rate by adjusting the number of loaded cells and, consequently, the number of recovered cells.
Note that for the Single Cell Gene Expression assay, it is possible to target up to 30,000 cells per library if using the 3' CellPlex Kit for Cell Multiplexing. Cell multiplets can be bioinformatically identified and filtered out when using the 3' CellPlex Kit.
