Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-rabbit serum as well as purified and partially purified Beta-galactosidase (E.coli).
Purification
Multi-step process including delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer
Western blot : 1/2,000-1/10,000. ELISA : 1/10,000-1/50,000. IHC : 1/1,000-1/5,000. The antibody recognizes both frozen tissue sections, paraffin embedded tissue and 4 % paraformaldehyde fixed tissue for most immunohistochemical analysis : A 1:1,500 dilution has been reported to detect beta-galactosidase in adult rat spinal cord tissue after infection with helper-dependent adenovirus expressing lacZ. In this particular experiment, tissue was perfused with 4 % paraformaldehyde and cryostat-cut (35 μm) to produce free-floating sections. A 1:5,000 dilution has been reported to be successful for staining of brain sections from transgenic mice expressing nuclear beta-galactosidase when assayed by immunofluorescence microscopy. A 1:5,000 dilution has been reported for immunofluorescent staining of methanol fixed, devitellinized Drosophila embryos. A 1:5,000 dilution has been reported to be successful for staining by immunoblot of beta-galactosidase fusion proteins after transfer using a semi-dry transfer apparatus.
