2017 was a year of accomplishment in the area of membrane protein research. From the structure determination of the MRP1 multi-drug resistance protein and the ABCA1 lipid exporter, to the first Cryo-EM structure of a GPCR (which is also the first full-length structure of a Class B GPCR), there were many novel structures published in 2017. In fact, 63 unique membrane structures were deposited last year alone. Bringing the overall total to 735!

This month we are celebrating all that has been accomplished in 2017. Higher standards in many areas of structural biology have been set, from crystallizing the LRRK2 protein on the International Space Station, to determining the structures of GPR40, TRPV6, and the GLP-1R:peptide complex...not to mention the incredible progress still being made in the field of Cryo-EM

At Anatrace, our year has been equally exciting, as we’ve added Molecular Dimensions to our roster – allowing us to further support the full gene-to-structure pipeline for both membrane and soluble proteins.

We thank you for your business with two special offers. To learn more, click here.


Anatrace is pleased to announce the recent characterization of the alkyl glucoside n-dodecyl-ß-melibioside (ß-DDMB) by Chuck Sanders and his lab at Vanderbilt University. This new detergent differs from traditional DDM in that it contains the disaccharide melibiose instead of maltose as the head group, giving it a slightly higher CMC and smaller micelles. The size of DDMB’s micelles doesn’t change with detergent concentration, temperature, pH, or ionic strength, like it does with DDM. For more information please click here.


The number of protein structures determined by cryo-electron microscopy (Cryo-EM) has increased in just one year by an impressive 46%. Membrane proteins determined by Cryo-EM has grown by an incredible 80% growth. We have compiled a table of the most recent structures for reference, along with the detergents used in their determination. To evaluate which Cryo-EM detergents and tools can help you in your research, please click here.


Researchers sent the Anatrace Microlytic Crystal Formers to the International Space Station to perform microgravity crystallization experiments of the LRRK2 protein. LRRK2 is one of the promising drug targets for the treatment of Parkinson’s disease because mutations in the gene encoding this protein are among the most common genetic causes.
