Many thanks to the members of the list who responded to my query! To sum up the responses: In human blood percentage of NKs varies from about 6% - 19% (some quote higher values) and it becomes higher with age. In rats it varies with strain and age in the range of 5% - 16%. Thanks again for the info. MK
