Protein A, Alexa Fluor™ 647 conjugate

Our Alexa Fluor™ 647 protein A conjugate binds to the Fc portion of various immunoglobulins from several different species. This exceptionally bright, far red-fluorescent probe (absorption/emission maxima ∼650/668 nm) can be used to visualize antibodies in a manner analogous to a labeled species-specific secondary antibody.
