Description
Penicillin G sodium salt is a biochemical-grade antibiotic salt with an activity of ≥1550 I.U./mg, CAS number 69-57-8 and empirical formula C₁₆H₁₇N₂NaO₄S. It has a molar mass of 356,37 g/mol and a density of 1,41 g/cm³, giving a clearly defined solid for laboratory weighing and solution preparation. In practice it is used when media, selection steps or assay systems require a controlled penicillin G sodium component. The material from manufacturer Carl ROTH fits routine preparation of aqueous stocks and culture formulations that call for this salt. Physical data and stated activity support consistent handling across standard biochemical protocols involving antibiotics and antimycotics. Laboratories working in cell culture and related applications can integrate the reagent where a sodium penicillin G salt at the specified unit activity is required.
This article is part of Antibiotics & antimycotics, in Biochemicals & reagents.

Questions about Penicillin G sodium sal, ≥1550 I.U./mg, for biochemistry, 10 g, plastic
What is this article?
Penicillin G sodium sal, ≥1550 I.U./mg, for biochemistry, 10 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Antibiotics & antimycotics, inside Biochemicals & reagents, in Microbiology lab supplies.
An antibiotic or an antimycotic for laboratory use is specified by potency, often micrograms per milligram, and by the spectrum it is used for in media. A hydrate and a free base differ in mass. Sterile solutions ready for culture and the dry powder are different articles. This is not a medicine for a patient.
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.
