애플리케이션
Aqueous solution may be used directly for derivatization without previous dialysis or gel permeation chromatography.
생화학적/생리학적 작용
β-galactosidase cleaves lactose into its monosaccharide components, glucose and galactose. It also catalyses the transglycosylation of glucose into allolactose, the inducer of β-galactosidase, in a feedback loop.

beta-D-galactosidase from Escherichia coli and horseradish peroxidase were evaluated as labels of Fab' in dose-response curves for human alpha-fetoprotein and human chorionic gonadotropin by sandwich enzyme immunoassay technique using fluorogenic substrates for enzyme assay. The non-specific binding of Fab'-peroxidase conjugates

Rabbit immunoglobulin G (IgG) was reduced by incubating with 10 mM 2-mercaptoethylamine and then treated with excess amounts of N,N'-o-phenylenedimaleimide. As a result, maleimide residues were introduced into rabbit IgG molecules. Rabbit IgG containing maleimide residues could be coupled to

A sensitive and specific double-antibody enzyme immunoassay (EIA) for a thyrotropin releasing hormone (TRH)-like immunoreactive substance has been developed. In order to synthesize TRH-labeled beta-D-galactosidase (beta-gal), a newly devised TRH derivative, pGlu-His-Pro-NH-(CH2)6-NH2 (TRH-Hex), was employed. TRH-Hex was linked to beta-gal

We and others have previously shown that a 67-kD cell surface elastin/laminin-binding protein (EBP) is responsible for cell adhesion to elastin and laminin and for mediating the process of elastin fiber assembly, but the nature of this protein was unknown.
