Description Back to Top
Reactive Blue 4-Separopore is a dye affinity matrix used to purify proteins based on selective binding interactions between certain protein sites and the dye molecule. Different immobilized dyes bind from 5 to 60% of the proteins in various crude cell extracts. The affinity for reactive dyes, such as Reactive Blue 4,to proteins may be due to substrate/cofactor similarities as well as hydrophobic and ion exchange properties. Some proteins have been found to require the addition of divalent cations for binding to dye resins. Reactive Blue 4-Separopore 4B-CL separates proteins based on affinity for this blue dye.
