Penicillin and streptomycin
Pen-Strep (also known as penicillin-streptomycin) is a mixture of penicillin G and streptomycin that is widely used in mammalian cell culture media to prevent bacterial contamination. The solution contains 5,000 units of penicillin G (sodium salt) which acts as the active base, and 5,000 micrograms of streptomycin (sulfate) (base per milliliter), formulated in 0.85% saline. In general, 50-100 un…For all aminoglycosides (by injection) There is a risk of auditory or vestibular nerve damage in the infant when aminoglycosides are used in the second and third trimesters of pregnancy. The risk is greatest with streptomycin. The risk is probably very small with gentamicin and tobramycin, but their use should be avoided unless essential.

Amoxicillin and penicillin are very similar drugs with a few differences, such as: the forms they come in. the conditions they treat. the more serious side effects they can cause. If you have a ...
Streptomycin Sulfate is the sulfate salt form of streptomycin, an aminoglycoside antibiotic derived from Streptomyces griseus with antibacterial property. Streptomycin sulfate binds to the S12 protein of the bacterial 30S ribosomal subunit, thereby inhibiting peptide elongation and protein synthesis, consequently leading to bacterial cell death.Use of Antibiotics and Antimycotics. The decision to use antibiotics to prevent contamination should be based on the individual researcher's needs and experience. The following table is a general guide for use of Gibco antibiotics in cell culture media. The concentrations given are for cell culture media containing serum; serum-free media ...Streptomycin was discovered by American biochemists Selman Waksman, Albert Schatz, and Elizabeth Bugie in 1943. The drug acts by interfering with the ability of a microorganism to synthesize certain vital proteins. It was the first antimicrobial agent developed after penicillin and the first antibiotic effective in treating tuberculosis.Pregnancy. Streptomycin can cause fetal harm when administered to a pregnant woman; because streptomycin readily crosses the placental barrier, caution in use of the drug is important to prevent ototoxicity in the fetus; if this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus
