Application Note: Using NDSB Reagents in Protein Isolation Workflows

When protein samples lose solubility during isolation, NDSB reagents can be screened as buffer additives to support a more manageable workflow. This application note outlines how NDSB 221, NDSB 195, and NDSB 211 can be evaluated by role in a protein isolation sequence.

Application Note: Using SAND and APG in Exploratory Photoreactive Protein Crosslinking Workflows

When researchers need to preserve short-lived protein associations long enough to compare conditions, a photoreactive workflow can be useful as an exploratory method. This application note shows how Sulfosuccinimidyl-2-(m-azido-o-nitrobenzamido)ethyl-1,3'-dithiopropionate (SAND) can be positioned as the primary reagent in that workflow, with p-Azidophenylglyoxal hydrate (APG) used as an example supporting reagent for comparison during method development.
