The process of getting crystals is not exactly science&#8230; It is a form of art and I am in awe of all those people who have contributed (over the years) to streamlining this process. Below I am showing one of the results of today&#8217;s work. The size of the well is about 2.5mm, which makes the crystal about 0.5mm (I guess&#8230; Give or take&#8230;). We got this bad boy shipped out, the results should be back on Friday. This, by the way, is by no means the final product!</p>

<p>In fact, we needed to painstakingly fish out this crystal with a micro-lasso sort of a tool (below), suspend it in special oil to get rid of water, and rapidly freeze it in liquid nitrogen (all the while trying to avoid the crystal from forming cracks).</p>

<p>You can see the holder with mounted crystals immersed in liquid nitrogen in the photo below.</p>

<p>The beast diffracted on the SGC machine but we&#8217;ll see the news from the synchrotron beam!</p>

<p>Of course I did not say what this protein is&#8230; Let me just say this: it is one of the trimethyllysine binding domains. I will elaborate on this in the future (and you will hopefully see where we are planning to take this from here).</p>
