Our R-phycoerythrin (R-PE) conjugate of NeutrAvidin® biotin-binding protein - a form of avidin that has been processed to remove carbohydrate and to lower its isoelectric point - can substantially decrease background due to nonspecific binding. The method used to deglycosylate the avidin retains its specific binding. This bright, fluorescent reagent is ideal for detecting biotinylated targets in flow cytometry applications.
