Description
L-Glutamine is an amino acid of minimum 99 % purity, specified USP and intended for biochemistry. It is identified by CAS number 56-85-9, empirical formula C₅H₁₀N₂O₃, molar mass 146,15 g/mol and density 1,47 g/cm³. The reagent is Laboratories use L-glutamine as a nitrogen source and metabolic intermediate in enzymatic assays, cell-related studies and general analytical biochemistry. Clear identity data, including EG number 200-292-1, support documentation, labelling and inventory control. is practical for method development and routine experimental use where consistent assay and reliable handling matter. Physical properties and purity grade align with standard biochemistry practice without extending beyond the stated specification.

Questions about L-Glutamine, min. 99 %, USP, for biochemistry, 100 g, plastic
What is this article?
L-Glutamine, min. 99 %, USP, for biochemistry, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Microbiology lab supplies.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
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.
