Tereza shares how switching to HexAuFoil grids gave her a 1Å resolution boost on a sub-100kDa membrane protein - while collecting less data and using fewer particles.

Learn how these grids simplify prep, improve reproducibility, and optimize Titan Krios setups.

Quantifoil and @sptlabtech.bsky.social Labtech are excited to be once again attending the CCP-EM Spring Symposium in Nottingham from 23-25th April 2025.

We hope to see some of you there - but don't forget you can attend virtually if you can't make it in person!

We spoke with Rectify about the first commercial use of HexAuFoil®, to gain new insights into the bile regulator BSEP.

Our grids improved resolution by almost 0.5 Å, helping eliminate toxic therapeutic candidates.

6) We were able to achieve these structures using our newly developed (an)aerobic freezing protocol using the SPT chameleon. This allowed us to generate high quality girds with thin ice without having to be in an anaerobic chamber!

This work is just our latest saga of tackling the complexities of the small heat shock proteins, following on our recent work with the human aB-crystallin that was just published: www.nature.com/articles/s41...

Dynamic fibrillar assembly of αB-crystallin induced by perturbation of the conserved NT-IXI motif resolved by cryo-EM - Nature Communications

Here the authors show that mutating αB-crystallin’s NT-IXI motif transforms polydispersed oligomers into ordered fibrils, enabling cryo-EM to provide insights into the principles of high-order assembl...

To kick things off here, we’re excited to share: The SLFN11 story continues! We combined cryo-EM and biochemical assays to explain how phosphorylation regulates SLFN11´s tRNA cleavage and ssDNA binding activities.

Oh my. This is just gorgeous from Misha Kudryashev's lab (I don't think he's here yet?). Love to see it. V ATPase resolved directly in synaptic vesicles 🤤 Lots of other neat observations in there also. Congrats to all involved! www.pnas.org/doi/10.1073/...
