Fluorochromes can be covalently conjugated to antibodies through reactions with thiol or amine groups. Typically, fluorochromes containing isothiocyanate, succinimidyl ester, or sulfonyl chloride reactive groups are conjugated to amines on the antibody molecules. WebPrepare a 10 mM stock solution of maleimide dye in anhydrous DMSO or DMF. Briefly vortex. Unused stock solution can be stored in the dark at –20 °C for up to a month. Prepare protein to be conjugated between 1–10 mg/mL in degassed pH 7–7.5 buffer such as 1× PBS, 10–100 mM Tris or 10–100 mM HEPES (other buffers can be used presuming ... dr thomas broderick
