Application Note:
This antibody shows inconsistent results between batches in ICC/IF, IF, IHC-P, IHC-Fr and IHC-FoFr. We have received several good Abreviews on these applications, however, we are unable to guarantee positive results. If the antibody is used for IHC, please try fixing with methanol and block with gelatine instead with BSA or NGS. After each antibody incubation, please wash 5x with TBS instead of PBS.We would recommend

Beta Galactosidase often called "β-gal" "b-galactosidase" or "b-gal" serves as an important enzyme that hydrolyzes β-galactosides into monosaccharides. It breaks down lactose into glucose and galactose which are easier to absorb. Beta-galactosidase expresses in many organisms such as *E. coli* where it is a well-known component of the lac operon. Its molecular weight in *E. coli* is approximately 116 kDa. The enzyme also appears in human tissues but is synthesized and regulated differently compared to bacterial systems.
Biological function summary
This enzyme is involved in the metabolism of galactose a critical aspect of cellular energy production. It can participate in various metabolic pathways converting complex carbohydrates into simpler sugars. In bacteria beta-galactosidase belongs to a protein complex controlled by the lac operon regulating lactose metabolism. In humans the enzyme takes part in lysosomal functions contributing to the degradation of glycoproteins and glycolipids therefore supporting normal cellular processes.
Pathways
Beta-galactosidase plays an important role in the lactose metabolism pathway. In *E. coli* it coheres with the enzymes of the lac system like lactose permease and transacetylase to facilitate lactose utilization. In human biology it participates in the lysosomal degradation pathway. Its function is associated with proteins such as galactosylceramidase which also break down galactolipids demonstrating its interaction in broader metabolic networks.
Deficiencies or malfunctions in beta-galactosidase lead to metabolic conditions like Galactosialidosis and Morquio syndrome Type B. These are lysosomal storage disorders caused by a lack of enzyme activity leading to accumulation of partially degraded macromolecules. The enzyme's impaired function connects with other proteins such as protective protein cathepsin A in the case of Galactosialidosis causing complex clinical symptoms through disrupted protein interactions and pathways.
