Let Our Cryo-EM
Experts Guide You

A team from Janssen Research used an integrative structural biology approach to study human malic enzyme 3 (ME3), a potential therapeutic target for pancreatic cancer.

Cryo-EM data were collected at NanoImaging Services under the leadership of Dr. Giovanna Scapin and Dr. Phat Dip. Baculovirus was generated by Dr. Peter Pushko at Medigen.

“Cryo-transmission electron microscopy was performed by NanoImaging Services, Inc…. Formulation morphology of the three lead candidate adjuvant formulations was assessed by cryo-transmission electron microscopy and compared to the morphology of a new batch of the proof-of-concept formulation manufactured at the same time as the lead candidate compositions.”

“We analyzed the structure of an epidermal growth factor receptor (EGFR) COBRA in solution using negative stain electron microscopy (EM) and small-angle X-ray scattering (SAXS)...To understand the structure of EGFR COBRA, we applied negative stain EM followed by single particle analysis that allowed us to visualize domains in this molecule at low resolution.

…[Grids of EGFR COBRA were prepared and] imaging was done by NanoImaging Services (San Diego, CA).”

“In this work, we conduct two orthogonal unbiased screens for potential metabolite ligands of eIF2B, identifying sugar phosphates as eIF2Bα binders and enzymatic activators. Using cryo-EM and X-ray crystallography, we elucidate structures of sugar phosphates bound to eIF2B and demonstrate that they occupy the ancestral catalytic pocket within the eIF2Bα subunit…

We thank…NanoImaging Services for assistance with cryo-EM data collection and processing.”

“...we report the cryo-electron microscopy structures of potent and inhibitory anti-hArg antibodies bound to hArg1 which form distinct macromolecular complexes that are greater than 650 kDa…With local resolutions of 3.5 Å or better we unambiguously mapped epitopes and paratopes for all five antibodies and determined that the antibodies act through orthosteric and allosteric mechanisms. ….Grids were prepared and data were collected at NanoImaging Services (San Diego, CA).”

“With moderate sample preparation, rapid data processing, and most importantly, unambiguous result interpretation, this [MicroED] approach can serve as a powerful tool in a pharmaceutical scientist's toolbox to determine the absolute configuration of a new API early in drug development, to ensure the quality of drug products, and ultimately, to improve the quality of life of patients.”
