[ccp4bb] Protein crystallization images recognition service, https://xtal.online/

Hi, Using MARCO database we trained DNN model for crystals image classification. It works a bit worse than MARCO (93% vs. 94%) but from other hand - it is easier to use by normal user (just need a web browser) and should be faster in general. Maybe somebody would be interested: https://xtal.onlin

Dear colleagues, I would like to draw your attention to an upcoming webinar to be presented by Janet Newman, Ph.D. titled "When you need a challenge, try protein crystallisation: Tips and suggestions for helping you over the hurdles." Janet currently runs theBio21 Collaborative Crystallisation Cen

Re: [ccp4bb] protein crystallization problem

Have you ever tried the condition of AS as precipitant and PEG as the additive? They have opposite functions on your protein's solubility:one increases and decrease it. Maybe you can vary the ratio of them to control your protein's solubility. And the xtals may be seen in some conditions. Go

[ccp4bb] protein crystallization problem

Dear All, I have several proteins that share a common problem. When crystallization, once the precipitant is PEG, the protein will be precipitated in seconds. Even the protein concentration is just 2 mg/ml. But if the precipitant is salt such as NH2SO4. The drop is clear for months, even high

[ccp4bb] Protein crystallization

Hi all I am dealing with a protein which size is about 200kDa. Due to the impurity and degradation problem, the protein has gone thru 3 purification steps (affinity column > ion exchange column > gel filtration column). The buffer condition for the last step of purification was 50mM MOPS pH7.0
