Ampicillin is an Inhibitor of bacterial cell wall synthesis and inhibits crosslinking of peptidoglycan by binding and inactivating of transpeptidases. Its spectrum is against gram-negative bacteria.

Ampicillin is sensitive to inactivation by ß-lactamase and can be used as a resistance marker.

Ampicillin sodium dissolves well in water.

The antibiotic is inactivated by autoclaving and a solution should be sterilized by means of filtration.

Cefotaxime is a beta-lactam type inhibitor of bacterial cell wall synthesis. The antibiotic inhibits the crosslinking of peptidoglycan by binding and inactivating of transpeptidases. Cefotaxime has high antimicrobial activity against gram-negative bacteria. By its molecular structure, the antibiotic is well protected against inactivation by beta-lactamase. Cefotaxime is often used for the elimination of Agro-bacterium species after inoculation. Non-toxic to plant cells.

G-418 is a member of the large family of Aminoglycoside antibiotics and has a molecular structure almost like Gentamycin. The antibiotic is an irreversible inhibitor of protein synthesis. Due to its structure is capable of binding to both prokaryotic and eukaryotic ribosomes and inhibiting protein synthesis and generating errors in the transcription of the genetic code.

G-418 can by inactivated by NPTII or 3APH. The hydroxyl group present at the 3 position of G-418 is phosphorylated by NPTII. The resulting steriometric change of the molecular structure of the antibiotic prevents it from binding at its ribosome binding site.

Hydroxyurea is an anti-neoplastic which Inactivates ribonucleoside reductase by forming a free radical nitroxide that binds a tyrosyl free radical in the active site of the enzyme. This blocks the synthesis of deoxynucleotides, which inhibits DNA synthesis and induces synchronization or cell death in S-phase.

Hygromycin B is an aminoglycoside produced by Streptomyces hygroscopicus. The antibiotic interferes with the translation step of polypeptide synthesis of prokaryotes and eukaryotes. The antibiotic inhibits peptide chain elongation by preventing elongation-factor EF-2 dependent translocation. Hygromycin B is used as a selective agent in yeasts, bacterial- and plant cells. The antibiotic is inactivated by means of incorporation of the APH 4 gene.

Kanamycin is an aminoglycoside antibioticum with bactericidal activity against many gram-negative bacteria. Aminoglycosides class antibiotics enter into sensitive bacteria via an active transport process. Inside the cell, aminoglycosides bind to the 30S and to some extent to the 50 S -subunits of the bacterial ribosome, inhibiting protein synthesis and generating errors in the transcription of the genetic code. Kanamycin is used as a selective agent in combination with the incorporation of the NPT II (AH3’) gene in plant tissue and microbial cells.

Tetracycline is a bacteriostatic antibioticum with activity against gram-positive and gram-negative bacteria. The antibiotic binds reversible to the 30S subunit of the ribosome, preventing the binding of aminoacyl transfer RNA and inhibiting protein synthesis and hence cell growth. Used as a selective marker for the transformation of plasmids encoding for tetracycline resistance (Tetr).
