Bringing the thread back up
This thread has been dormant for a couple of months, but it seems to be the right time for it to be reawakened.
There is much relevant information here for you, Grant, and perhaps forr other newcomers too.
BTW Norb, when looking through the posts I saw our discussion about where the “clonicity” was – the B-cells or the IgM. Last time I saw my hematologist, he explained to me that the IgM was a protein and thus not consisted of cells, just molecules, so it certainly was the B-cells that cloned themselves – or itself, if you like.
