Dear all, I got crystals in 1.4 M sodium/potassium phosphate, ph-8.2 condition. Could anyone tell me what is the best cryprotectant for this above condition. Thanks -- WITH REGARDS Rohit Kumar Singh Lab. no. 430, P.I. Dr. S. Gourinath, School of Life Sciences, Jawaharlal Nehru University N

Adding Tacsimate on top of the basic conditions worked best for us. On Tue, Dec 23, 2014 at 11:11 AM, rohit kumar wrote: > Dear all, > > I got crystals in 1.4 M sodium/potassium phosphate, ph-8.2 condition. > > Could anyone tell me what is the best cryprotectant for this above > condition. > >

You can try adding 10% or 20% glycerol to your Cryo that works for us. On Tue, 23/12/14, Yarden Opatowsky wrote: Subject: Re: [ccp4bb] best cryprotectant To: CCP4BB@JISCMAIL.AC.UK Date: Tuesday, 23 December, 2014, 2:47 PM Adding Tacsimate on top

We usually try 25-30% glucose first. Weigh out 150 mg of glucose in a microcentrifuge tube add well solution, dissolve, mix, and make up to the 0.5 mL mark with well solution. If crystals crack in this solution, make up a 40% glucose solution in mother liquor, and add this solution in 0.25 drop
