Re: autofluorescence and drugs

Hi
I've stained a lot of cells from people on various HAART therapies and not found
any unusual autofluorescence. Anthracyclines used in tumor therapy are brightly
fluorescent. Are you seeing real autofluorescence in cells without any staining or
is it non-specific binding of your antibodies? I've seen non specific binding of all
antibodies after monkeys and humans have been treated with anti CD3 and CD8 antibodies
due to an humoral immune response to the "theraputic " antibodies. Washing cells before
staining prevented it.

Good luck

Hello to all,

I have just tested a patient on antiretroviral therapy whose cells
fluoresced to the extent that compensation was impossible.   This has
prompted 2 questions,

1.	Does anyone know of a list of drugs (prescribed or "recreational")
which cause this phenomenon?

2.	How do you deal with these patients? Do you lyse and wash before
staining?  If so, how would this effect your results?

Thanks

Jenny
