Can we use sorted cells (e.g., FACS or MACS sorting) as input material?Home FAQ Applications Can we use sorted cells (e.g., FACS or MACS sorting) as input material?Yes, you can use FACS or MACS sorted cells as input material. In this case, we strongly recommend measuring the cell concentration and viability after the sorting, to ensure that the input material is of good quality and meets the loading requirements (since the counting from the sorter is usually not well estimated).
