β-galactosidase

Fig. 4. Serial 2-fold dilutions of

ββ-galactosidase, run on a Criterion™ Tris-HCl 4–20% gel.

The gel was stained with Flamingo Fluorescent Gel Stain and imaged with the Molecular Imager FX

system. Fluorescence associated with the

β-galactosidase band was determined using Quantity One

®

1-D Analysis Software. A

A: Fluorescence associated with protein band in the range 0.25–4 ng. B

B:

Fluorescence associated with protein band in the range 4–60 ng. C

C: Fluorescnece associated with protein

band in the range 60–960 ng.
