Guanidine hydrochloride (Aminoformamidine Hydrochloride) is a strong organic base existing primarily as guanidium ions at physiological pH. It is found in the urine as a normal product of protein metabolism. It is also used in laboratory research as a protein denaturant.

Kanamycin sulfate (Kanamycin monosulfate) is an aminoglycoside antibiotic that interferes with protein synthesis by binding to the 70S ribosomal subunit of bacteria. Kanamycin sulfate exhibits antimicrobial activity against both Gram-positive and Gram-negative bacteria, as well as mycoplasmas.

Ampicillin Sodium is the sodium salt form of ampicillin, a broad-spectrum semisynthetic derivative of aminopenicillin. Ampicillin sodium (Domicillin) inhibits bacterial cell wall synthesis by binding to penicillin binding proteins, thereby inhibiting peptidoglycan synthesis, a critical component of the bacterial cell wall.

EDTA copper(II) disodium salt is a metal chelator with antimicrobial, anti-inflammatory and antioxidant activity, slows down damage caused by metal ions, maintains osmotic pressure during protein purification, and can be used in the study of neurological disorders.

5-Fluorouracil (5-FU) is a uracil analog and inhibitor of DNA synthesis, exhibiting antitumor activity by affecting pyrimidine synthesis through thymidylate synthase inhibition; it induces apoptosis and autophagy.

Metronidazole (Metronidazol) is a synthetic nitroimidazole derivative with antiprotozoal and antibacterial activities.

G-418 disulfate (Geneticin sulfate) is an aminoglycoside antibiotic that selectively inhibits eukaryotic protein synthesis by blocking peptide chain elongation.

Cefaclor monohydrate (Cefaclorum) is a beta-lactam, second-generation cephalosporin antibiotic with bactericidal activity.
