Dear Rakesh, Congratulations that you have crystals in the first place! I am sure you will hear this from others as well, but you did not tell us how you tested your crystals for diffraction. It is not uncommon that crystals diffract beautifully in their native environment of the crystallisation dr

Hey Rakesh, Such are the questions that every crystallographer faces in his/her everyday life. I am not sure if there is any straight forward answer. So make voyages ! Terese Bergfors mentioned in her famous book, "Protein crystallization" a case where a Scientist from Umea Uni got the diffraction

Have you tried including a small amount of chymotrypsin? There were quite a few papers about this technique 10-15 years ago. It worked for one of our proteins, but I'm not sure about its success with complexes. Good luck, Jon.C. Sent from ProtonMail mobile Original Message On
