[Histonet] X-gal staining and fixation
Dear histonet members,
I have been working on X-gal staining of cultured cells with iron cyanide
solution to see the efficiency of adenovirus transfection, and decaying of
cell structure is bothering me. I fixed cells with 1%glutaraldehyde/PBS(-)
for 30 min followed with 0.2% Triton-X/PBS(-) for 10 min before incubation
with iron cyanide solution. The cell structure looks fine soon after
fixation, but some junks/debris of cells start floating soon after
incubation with X-gal solution. Higher conc of glutaraldehyde preserves
the structure more robustly, but at the same time it denatures the
beta-galactosidase and loses the blue color.
I would deeply appreciate your comments/suggestions/advice.
