APTS [8-Aminopyrene-1,3,6-trisulfonic acid, trisodium salt]

• Cat.No.: DYE-111

Specification

• Description: The polyanionic dye APTS with an amino group that can be coupled to an aldehyde or ketone group to form a Schiff base. The Schiff base is usually chemically reduced by sodium borohydride (NaBH4) or sodium cyanoborohydride (NaB(CN)H3) to form a stable conjugate. APTS is a polar tracer that also can be used in combination with the cationic quencher DPX (#6271) for membrane fusion or permeability assays, including complement-mediated immune lysis. We also offer other related dyes, please see bottom of the page.
