Cleaving intermolecular (between subunits) disulfide bonds allows the subunits of a protein to separate independently on SDS-PAGE. Cleaving intramolecular (within subunit) disulfide bonds allows the subunits to become completely denatured so that each peptide migrates according to its chain length with no influence due to secondary structure. suitable for derivatisation of Amine groups Recommended products Discover LiChropur reagents ideal for HPLC or LC-MS analysis Safety: Symbol    GHS05, GHS06, GHS08, GHS09 Signal word  Danger Hazard statements  H301 + H331-H310-H315-H317-H318-H373-H410 Precautionary statements  P261-P273-P280-P301 + P310-P302 + P350-P305 + P351 + P338 Target organs  Heart, Liver RIDADR  UN 2966 6.1 / PGII WGK Germany  3 RTECS  KL5600000 Flash Point(F)  165.2 °F Flash Point(C)  74 °C
