Description
LB-Agar (Luria/Miller) / Amp50 is a ready nutrient medium formulated for molecular biology applications. This Luria/Miller LB agar variant incorporates ampicillin selection at the Amp50 level, supporting growth and screening of ampicillin-resistant bacterial strains on solid plates. The medium follows the established Luria/Miller composition familiar to molecular biology laboratories, helping ensure consistent colony formation and reliable antibiotic selection. quantity suits frequent plate preparation in research and teaching environments. Prepare and pour plates according to standard laboratory practice for LB agar with ampicillin. Use this selective agar wherever Amp50 LB plates are specified for E. coli and related host systems in gene cloning and expression projects.

Questions about LB-Agar (Luria/Miller) / Amp50, for molecular biology, 500 g, plastic
What is this article?
LB-Agar (Luria/Miller) / Amp50, for molecular biology, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dehydrated culture media (agar & broth bases), inside Culture media & microbiology, in Microbiology lab supplies.
A dehydrated medium is a powder the laboratory dissolves, sterilises and pours. The formulation name, the supplements it still needs, and the grams per litre are the specification. Two powders with similar names, one selective and one not, grow different organisms.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
