Packaging

25 L in steel cylinder
Standard products are packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180 valve. Nominal gas pressures at 21ºC are 850 psig for 25 L and 1570 psig for 45 L. Care must be taken when extracting this product from the cylinder.
All gas volumes are quoted at Standard Temperature and Pressure (STP) and not at Normal Temperature and Pressure (NTP). One STP Liter is 7.7% more gas than one NTP Liter.
This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.

A general method to analyze the structure of a supramolecular complex of amyloid fibrils at amino acid residue resolution has been developed. This method combines the NMR-detected hydrogen/deuterium (H/D) exchange technique to detect hydrogen-bonded amide groups and the ability of...

Probing the conformational changes of amyloid beta (Aβ) peptide aggregation is challenging owing to the vast heterogeneity of the resulting soluble aggregates. To investigate the formation of these aggregates in solution, we designed an MS-based biophysical approach and applied it...

The higher order structure of protein therapeutics can be interrogated with hydrogen/deuterium exchange mass spectrometry (HDX-MS). HDX-MS is now a widely used tool in the structural characterization of protein therapeutics. In this review, HDX-MS based workflows designed for protein therapeutic...
