I can't help myself. If you are refering to X-gal staining, how much
simpler can it get? The cells are fixed in formaldehyde diluted from 37%
stock solution, which is bought ready to go. The salts are prepared as a
stock solution, perfectly stable at room temp, the X-gal as a stock which
is stable at -20. Some protocols call for detergents in the stain, but
these are not necessary for staining cells. Perhaps your protocols are
Sorry if you are refering to some other type of detection, but X-gal
staining is simplicity itself and the procedure is quite robust. Heck, if
you just add X-gal to the medium the cells will slowly turn blue.
(Unfortunately, this kills them). I'm not automatically anti-kit, some of
them are real time savers, but I can't see this one.
