Library vendor poll!

A good fragment library is essential for generating good fragment hits. Earlier this year we asked about fragment size and library size, and summarized the results here.

Some folks make their own fragments, but this is expensive, and it’s probably fair to say that most fragment libraries contain a large fraction of commercially available compounds. Unfortunately, what you buy is not always what you get: sometimes the wrong compound is sent, or the compound is not as pure as advertised. As this post makes clear, different vendors have different track records.

Two years ago we highlighted a number of fragment library vendors. The current poll first asks whether you’ve bought fragments in the past several years. (Please answer this question as otherwise I have no idea how many people actually vote.)

If the answer to the first question is yes, the second question asks which vendors you would recommend buying from – presumably because you’ve had good experiences with them in the past few years. You can vote for as many as you’d like.

Finally, the third question asks which vendors you would avoid.

Please vote on the right-hand side of the page, and feel free to leave comments below, particularly if you've used vendors not on the list.

And on the subject of voting, if you are eligible to vote in the United States, please make sure to do so before the polls close on November 6.

Democracy atrophies when citizens don’t exercise their rights.
