Kojic acid lightens surface pigmentation, while glutathione brightens the skin from within for overall whitening
However, adverse effects may limit the treatment potential, e.g., glitazones are associated with phenotypical weight gain [136] and obeticholic acid induced pruritus and elevated LDL-C [137], the latter a potential concern in patients already at risk for cardiovascular disease

Features of Protein A/G Magnetic Beads: High capacity nearly four times higher binding capacity than typical magnetic beads from other suppliers, allowing the use of smaller amounts per experiment Low non-specific binding stable, pre-blocked beads provide clean purification products (e.g., antigen eluted in IP with antibody is devoid of contaminating proteins from complex IP matrix) Flexibility convenience of IgG binding domains of both Protein A and Protein G on one bead Compatibility beads are compatible with manual and automated applications (e.g., Thermo Scientific KingFisher Instruments) Assay consistency magnetic beads eliminate resin loss and provide for more efficient separation of solutions than traditional IP methods that use only microcentrifuge tubes These magnetic beads are coated with genetically engineered Pierce Protein A/G, a recombinant fusion protein which combines the IgG binding domains of both Protein A and Protein G
