USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.

β-Galactosidase assay is for determining the β-galactosidase activity in the lysates of cells transfected with a β-galactosidase expression construct. It uses chlorophenol red-β-D-galactopyranoside (CPRG), which is up to 10 times more sensitive than the classic O-nitrophenyl-β-D-galactopyranoside (ONPG) β-Galactosidase assays. This increased sensitivity makes it simpler to measure β-galactosidase activity in cells that are difficult to transfect or have low β-galactosidase activity expression. β-Galactosidase activity is measured using a spectrophotometer or a microplate reader to determine the amount of substrate converted at 570 to 595 nm.

Supplier: PerkinElmer

Standard rectangular macro cuvettes frequently used in spectroscopy for routine liquids analysis. They have cell windows that are fused to the bodies by a special process which avoids deformation of the windows. This assures that the full width of the cell is usable and the finished cell dimensions are maintained.
