Dear prem, I am sharing my experience with needle crystal that worked for me. 1.First check that salt or a protein crystal by SDS PAGE or mass spectroscopy. 2. For improvement of morphology and size, you could try microseeding of your crushed crystal, generally needle crystal appear quickly, fur

I can share what has worked for my crystals : 1. You can put a grid across your condition with same or altered drop ratios. 2. You can try micro seeding. (This has given me the best results so far). 3. You can try Hampton's additive screen. On Sun, Sep 8, 2019 at 10:09 AM Prem Prakash wrote:

Dear Prem, before moving on with any optimization rounds it would be good to first confirm that these crystals are actually protein crystals, and in particular the protein of interest. For example, a Silver-stained SDS-PAGE gel can be very informative. You can run a couple of your crystalline c
