β-Galactosidase Labeling of IgG Antibody

  • G. Brian Wisdom

Abstract

The Escherichia coli β-galactosidase (EC 3.2.1.23) is a large enzyme (465 kDa) with a high turnover rate and wide specificity. Unlike several other enzyme labels it is not found in mammalian tissues, hence background contributions from these sources are negligible when this label is measured at a neutral pH.
