Chloramphenicol
CAS :Chloramphenicol is produced by Streptomyces venezuelae. It is a broad-spectrum antibiotic with bacteriostatic properties. It interferes with bacterial protein synthesis by reversibly binding to the 50S ribosome unit. Used as substrate in the CAT (chloramphenicol acetyl transferase) assay, where the CAT gene expression is monitored by the ability of a system to transform chloramphenicol into acetyl chloramphenicol, which can be followed by simple thin layer chromatography. It is employed in VTM to prevent bacterial growth during specimen storage and transportation.Formule :C11H12Cl2N2O5Degré de pureté :Min. 98 Area-%Couleur et forme :PowderMasse moléculaire :323.13 g/molNitrocycline
CAS :Nitrocycline is a broad-spectrum antibiotic, which is a synthetic derivative of tetracycline with enhanced antibacterial properties. As a chemically synthesized compound, nitrocycline has been engineered to overcome resistance mechanisms common in bacterial pathogens. Its mode of action involves the inhibition of protein synthesis, achieved by binding to the 30S ribosomal subunit, effectively preventing the addition of new amino acids to nascent peptide chains. This binding action interrupts bacterial growth and replication, providing robust activity against both Gram-positive and Gram-negative bacteria.

CAS :Vancomycin is a tricyclic glycopeptide antibiotic that has bactericidal effects against staphylococci, streptococci, and other gram-positive bacteria. It is often used as an alternative treatment for severe staphylococcal and streptococcal infections, including endocarditis, and infections with MRSA (methicillin-resistant Staphylococcus aureus), penicillin-resistant pneumococci or in cases of allergy to penicillins and cephalosporins.

CAS :Cefoxitin sodium salt is a cephamycin-type antibiotic, which is a semi-synthetic derivative of cephalosporin. As a beta-lactam antibiotic, it is derived from the fermentation of *Streptomyces lactamdurans* and chemically modified to enhance stability against certain bacterial beta-lactamases. Its primary mode of action involves inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins, disrupting the transpeptidation or cross-linking of peptidoglycan layers. This action effectively prevents the bacteria from maintaining cell wall integrity, leading to cell lysis.Formule :C16H16N3NaO7S2Degré de pureté :Min. 98.0 Area-%Masse moléculaire :449.43 g/molRef: 3D-C-2480

CAS :Chlorotetracycline monohydrochloride is an antibiotic compound specifically designed for culture media use. It is derived from a naturally occurring tetracycline produced by the bacterium *Streptomyces aureofaciens*. As a broad-spectrum antibiotic, chlorotetracycline functions by inhibiting protein synthesis in susceptible bacteria. It binds to the 30S subunit of the bacterial ribosome, blocking the attachment of aminoacyl-tRNA to the ribosomal acceptor site, which effectively halts translational elongation.Formule :C22H24Cl2N2O8Degré de pureté :(Chlortetracycline Hcl) Min. 89.5%Couleur et forme :Yellow PowderMasse moléculaire :515.34 g/molMidecamycin
