Rho1D4 peptide

The Rho1D4 peptide is a 9 amino acid long chain whose purpose is the elution of proteins that are bound to Rho1D4 affinity beads during the corresponding protein purification procedure.
The main principle here is competetive binding. Since the small Rho1D4 peptides can be added in excessive amounts into the elution buffer they outcompete the bound Rho1D4-tagged proteins by binding to the affinity beads instead. This way the proteins are eluted and the final step of the purification is done.
