Thanks to all , The protein storage buffer has MgCl2, As per your observaitions, it might be this combination gave me the hexagon crystal,
but I have decided to put them in beam this week, Will report as soon as i get a few images. thanks once again to all, S.Jayashankar Research Student Institute for Biophysical Chemistry Hannover Medical School Germany.
