Description
X-beta-Gal is a BioScience-Grade chromogenic substrate supplied at a minimum purity of 99 % for molecular biology and genetic-engineering applications. The compound has the empirical formula C₁₄H₁₅BrClNO₆, a molar mass of 408,6 g/mol, CAS number 7240-90-6 and EG number 230-640-8. It is widely used in blue-white screening and related reporter assays where β-galactosidase activity is visualised through colour development. Categories linked to the product include genetic engineering and reagents employed in virus detection and related research contexts. X-beta-Gal from manufacturer Carl ROTH is positioned for laboratories that require a defined high-purity grade for reproducible bioscience protocols. The solid reagent supports standard molecular cloning and screening procedures when prepared according to established laboratory methods. Clear identity data (CAS, EG number and formula) facilitate documentation in regulated or fully traceable research environments.

Questions about X-beta-Gal, min. 99 %, BioScience-Grade, 100 mg, glass
What is this article?
X-beta-Gal, min. 99 %, BioScience-Grade, 100 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
Which category should I open next?
