Alkali Scientific Carbenicillin, Disodium Salt, 25 G

Carbenicillin Disodium Salt is a beta-lactam antibiotic widely used in microbiology and molecular biology for selective inhibition of bacterial growth. It acts by disrupting cell wall synthesis, leading to bacterial cell death. Carbenicillin is frequently used in cloning and transformation experiments to maintain plasmid selection in bacterial cultures. It is more stable than ampicillin and reduces the formation of satellite colonies, ensuring clearer selection results. This compound is suitable for use in laboratory media and cell culture applications where consistent antibiotic activity is required. It supports research involving genetic engineering, microbial growth control, and studies of antibiotic resistance mechanisms.

Gold Biotechnology Inc Carbenicillin Solution

Carbenicillin is a member of the penicillin -lactam antibiotics However unlike most -lactams carbenicillin disodium is limited to primarily gram-negative bacteria including Pseudomonas aeruginosa and common enteric species It can be used in selection protocols and is often preferred over ampicillin due to its increased stability This allows for less contamination of unwanted bacterial colonies In addition carbenicillin has been used to regulate bacterial growth in plants yielding low regeneration frequencies It can be used in genetic transformation applications to select for AmpR transformed cells

Medchemexpress LLC Phosphoribosyl pyrophosphate pentasodium | 108321-05-7 | 99.4% | 499.98 | 5 MG

Phosphoribosyl pyrophosphate (PRPP) pentasodium is an important metabolite required in the biosynthesis of purine and pyrimidine nucleotides, the amino acids histidine and tryptophan, and the cofactors NAD and NADP. It is an important intermediate in cellular metabolism, synthesized by PRPP synthase (ribose 5-phosphate + ATP → PRPP + AMP). PRPP is ubiquitously found in living organisms and is used in substitution reactions with the formation of glycosidic bonds. It is also utilized in the biosynthesis of tetrahydromethanopterin, arabinosyl monophosphodecaprenol, and certain aminoglycoside antibiotics.

Important metabolite in the biosynthesis of purine and pyrimidine nucleotides, histidine, tryptophan, NAD, and NADP.
