Additional Information

Use heavy BS2G-d4 deuterated crosslinking reagent in combination with the non-deuterated analog BS2G-d0 (BS2G-d0, BS2G) for mass spec studies. Together BS2G-d0 and BS2G-d4 can be used for protein-protein interaction mapping using Liquid Chromatography–Mass Spectrometry (LCMS, LC/MS, LC-MS).
