Slightly off thread but can I ask what you were using the Dynal beads for
and if you know why they were not succesful. I have been using dyna-beads to
seperate out T-cells and APC populations and I usually find the cells
aggregate by the time I have finished the procedure. From 40x10(6) PBMC I
usually am lucky to recover 2x10(6) T-cells. If MB have a better system I
would be interested.
