Rashmi,
To facilitate dissolution of a peptide we found ultrasound (in glass, plastics 
absorb much of the energy) useful. It might be also helpful to warm the 
solution mildly.

[ccp4bb] dissolving peptides !

2010-06-07 Thread rashmi panigrahi
Hello everybody,
I have a 16 mer peptide which is predicted to be positively charged alpha
helix and has 50% of its sequence hydrophobic.

Could any one recommend the best way to dissolve it, and then it can be used
for crystallization trials.

thanks

Rashmi,
You can try 1%DMSO and also acetonitrile but the former is preferable.
