anti-AAV VP1/VP2/VP3, B1, mouse mab, AFDyeTM 647

The B1 antibody reacts with free VP1, VP2 and VP3 of adeno-associated virus (AAV) and at a reduced degree with assembled viral particles. VP1 and VP2 are highly enriched in the nucleus, while non-assembled VP3 is evenly distributed in the nucleus and the cytoplasm. Epitope mapping experiments (Wobus et al., 2000) identified aa726 to aa733 (C-terminus; common to all 3 VP proteins) as the specific binding region. The antibody is also useful for characterization of different stages of infection. The AFDye™ 647 is a bright, far-red-fluorescent dye ideally suited for the 633 nm or 647 nm laser lines (excitation/emission 648/671 nm). It is structurally similar to Alexa Fluor® 647, and can be used with a common Cy5 filter set. A significant advantage to using long wavelength dyes such as Cy5 or AFDye™ 647 dye over other fluorophores is the low autofluorescence of biological specimens in this region of the spectrum.
