MW 66800 g/mol.
A conjugate of BSA (bovine serum albumin, MW = 66.4K) and the beta-galactosidase substrate carboxyumbelliferyl beta-D-galactopyranoside ab275363 produces a protein that can be used to measure extracellular β-galactosidase activity, measure lacY permease activity, for microinjection analyses, or measure cell disruption or lysis.

Notes
The fluorescence spectrum for 3-carboxyumbelliferone is pH-dependent. Below the pKa (7.8), Abs shifts to shorter wavelengths (325-340 nm) and fluorescence intensity decreases. These shifts may be used to measure compartmentalization of intracellular activity.
