I am currently trying to isolate macrophages from the anterior kidneys of
juvenile salmon using discontinuous Percoll gradients followed by
adherence to plastic multiwell plates. I have sucessfully recovered
phagocytes, but my problem is that I don't get enough of them and I can't
get them reliably. Sometimes i get as many as 1-2 * 10^6 cells from a
fish but more often I only recover 10^5 from a similar fish at the same
time. I would be interested in hearing from anyone who has worked with
percoll gradients or fish phagocytes who might know what factors might be
affecting my cell yield. Thanks.
