Physical form Contains Tris buffer salts and magnesium chloride Application -Galactosidase is conjugated to an antibody which specifically recognizes a target molecule (enzyme immunoassay or EIA).[1]-Galactosidase is also used as a reporter enzyme to monitor the level of gene expression of a promoter.[2]It may be used as a positive control protein with anti--galactosidase antibodies. Biochem/physiol Actions -galactosidase cleaves lactose into its monosaccharide components, glucose and galactose. It also catalyses the transglycosylation of glucose into allolactose, the inducer of -galactosidase, in a feedback loop. General description -Galactosidase is a tetramer consisting of four equal subunits of 135,000 each. It is a sulfhydryl containing enzyme, with 19 cysteine residues per subunit.[3] Physical properties Tetramer molecular weight 465 kDa (subunits 116.3 kDa each) Safety Information Personal Protective Equipment Eyeshields,Gloves,type N95 (US),type P1 (EN143) respirator filter RIDADR NONH for all modes of transport WGK Germany 3 RTECS LW5840000
