What is the minimum number of cells that can be efficiently processed with the QIAamp DNA Mini and QIAamp Blood Mini kits and what is the expected yield?
In QIAGEN labs, we have isolated DNA from a minimum of 1000 cells or 1 ul of whole blood sample. The expected yield from 1 ul of whole blood with 4000-7000 leukocytes is 30 ng of genomic DNA. The expected yield of genomic DNA from a single eukaryotic cell is 6 pg. However, please bear in mind that for these small quantities, we would recommend the QIAamp DNA Micro kit instead.
