How much of it do you need?
Also, do you just want to break them up into individual cells or is there something more? When I started reading I immediately thought Trypsin, but that sucker has to be shipped in dry ice and kept at -80 and even then it degrades itself... unless it's a mix of Trypsin/EDTA in medium in which case it'll last a few weeks in the fridge or months if frozen. Anyway, how much do you need and what exactly are you planning to do (unless it's a secret)? If it's just counting, i.e. breaking up clumps, you'd need just a few mL... I might be able to help... And there are plenty of other agents you could use (but all of them are probably only sold to labs). I'll get back to you in a few days.
