Hello,
I would be VERY interested in any responses you might get! We are
struggling with sorting stem cells onto slides and keeping them down during
a subsequent FISH labeling procedure...thanks in advance.

response #1
When sorting onto slides we use very dilute saline (10 ml of Isoton in 2
litres of distilled water). We then dry at 50 degrees. We do not coat
slides.
Cells adhere well. Droplet deflection is just as good.
Good luck.

Lan Bo Chen, around the corner from you at the Farber has some
magical slides that he gets from Germany. The slides are treated by
a proprietary method. He claims to retain >90%
of the cells through rigorous processing.

response #3
Centrifugal Cytology works. I haven built special buckets. The slides
should be clean and then coated with polylysine or the best binding will be
with Meyer's Albumin fixative. The trick is to fix the cells while the
centrifugal field is applied. Glyoxal is a good fixative.
