I've even had success using just 1X PBS in 90% glycerol without anti-fade. I store my samples at 4C in the dark and they are good for many months. You just need to be aware of how much light you are exposing your cells to. You could add a little propyl gallate if you want an anti-fade in it.

I would guess DPX is fine so long as you aren't just absolutely drenching your sample with light.

Hi,  the DPX mounting medium is fine, and I did not use anti-fade.

Good luck

Thanks all,

Dear Jardon R Yaron, you just cleared my confusion completely. i was also intending to use Glycerol (50%), Tris Hcl (0.1 M, pH 9) along with 0.5% n propyl gallate. But i was not sure as which extent this is gonna work. You just strengthened my plan of using glycerol propyl gallate as the mountant. However, I would bother you once more, " Shall this mounting medium keep the cover slip stuck to glass slide, I mean won't it slip away? and can I store the slides after mounting at 4 degrees or is it better to store at -20 degrees for better results?

Thanks 

With any non-hardening mounting medium you want to make sure you seal the coverglass with a cyanoacrylate like nail polish top-coat. My favorite is Revlon Quick-Dry Top Coat.

Store the slides in the dark at 4 degrees. They should last at least 3+ months.

With an aqueous mounting medium I personally never store at -20C because I worry about expansion and distortion of my samples.
