We have also used the one from Calbiochem too in the past. However, it has been bought by Merck, which now sells FluorSave. In my opinion, nothing has changed formulation wise except the name of the company.

Hope this helps

Thank you so much.

From what I can tell, calibiochem is now owned by Merck, so it should be the same

After coverslipping with FluorSave, do you store your slides at room temperature? Do you have an idea of how much fading occurs after about a month? [I use VectaShield, which works well and fluorescence is fairly stable for years, but the slides have to be at 4°C or cooler. I'd prefer room temp storage]
