Research Products International Corp Chlortetracycline Hydrochloride, 25 Grams

Chlortetracycline Hydrochloride is a tetracycline antibiotic. Chlortetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex. The interference disrupts the translation process and inhibits bacterial growth.

This antibiotic offers a broad spectrum of antibacterial activity against both Gram-positive and Gram-negative bacteria. It also forms complexes with calcium, magnesium, aluminum, and iron, leading to reduced absorption.

Additionally, it is useful to study bacterial susceptibility patterns or as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic.

Research Products International Corp D-Cycloserine, 1 Gram

D-cycloserine is an antibiotic and structural analog of the amino acid D-alanine. It inhibits cell wall synthesis in certain bacteria, including Mycobacterium tuberculosis.

While it was initially identified as an antibiotic, D-cycloserine has gained attention for its activity as a partial agonist at the N-methyl-D-aspartate (NMDA) receptor, a type of glutamate receptor in the brain. Researchers study the mechanisms of neurotransmission and synaptic plasticity due to its interactions with NMDA receptors.

Research Products International Corp Cycloheximide, 1 Gram

Cycloheximide is a fungal-derived compound used particularly in molecular biology, microbiology, and cell biology. It inhibits protein synthesis in eukaryotic cells by interfering with the translocation step during protein elongation on the ribosome. It binds to the 60S ribosomal subunit and prevents the movement of peptidyl-tRNA from the A-site to the P-site, inhibiting the synthesis of new polypeptide chains.

WARNING! This product can expose you to Cycloheximide, a chemical which is known to the State of California to cause developmental harm. For more information go to www.P65Warnings.ca.gov.

Research Products International Corp Erythromycin, 25 Grams

Erythromycin is an antibiotic in the macrolide class. It is derived from the bacterium Streptomyces erythreus and inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. This action effectively prevents the growth and reproduction of bacteria.

Employed as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Erythromycin is effective against a broad spectrum of bacteria, including Gram-positive bacteria (such as Streptococcus, Staphylococcus, and Corynebacterium species) and some Gram-negative bacteria (such as Haemophilus influenzae and Neisseria gonorrhoeae).

Research Products International Corp Penicillin G Sodium Salt [Benzyl Penicillin Sodium Salt], 25 Grams

Penicillin G sodium is the sodium salt form of penicillin G, which is a narrow-spectrum beta-lactam antibiotic. It is one of the earliest and most widely used antibiotics, belonging to the penicillin class of antibiotics.

Penicillin G sodium interferes with bacterial cell wall synthesis. It inhibits the enzyme transpeptidase, which is involved in the cross-linking of peptidoglycan chains in the bacterial cell wall. This disruption weakens the cell wall structure, leading to cell lysis and death.

Also, Penicillin G is effective against a wide range of Gram-positive bacteria, including Streptococcus, Staphylococcus, and some anaerobic bacteria. It is less effective against Gram-negative bacteria.

Often used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its inclusion in culture medium allows for the specific growth of bacteria lacking resistance to penicillin G.

Research Products International Corp Spectinomycin Dihydrochloride Pentahydrate, 5 Grams

Spectinomycin dihydrochloride pentahydrate is an antibiotic that is commonly used in the life science marketplace. It belongs to the class of aminocyclitol antibiotics and is primarily utilized for its activity against gram-negative bacteria.

Spectinomycin dihydrochloride pentahydrate finds applications in various fields such as research, molecular biology, and biotechnology. It is commonly used as a selective agent in cell culture systems and is added to growth media to prevent the growth of bacteria that may contaminate cell lines.

Also, it is particularly effective against certain strains of gram-negative bacteria, including Escherichia coli. It works by inhibiting protein synthesis in bacteria, which ultimately leads to their death. Its selective action makes it valuable for maintaining sterile conditions and selecting cells that have taken up foreign genetic material in molecular biology experiments.

Research Products International Corp Rifampicin, 1 Gram

Rifampicin is an antibiotic used for its potent antibacterial properties. It belongs to the class of antibiotics known as rifamycins. Rifampicin is particularly effective against bacteria, including Mycobacterium tuberculosis, which causes tuberculosis, and other bacteria that can lead to various infections.

The mechanism of action of rifampicin involves inhibiting bacterial RNA synthesis by binding to the beta subunit of bacterial DNA-dependent RNA polymerase. This interference disrupts the transcription process, preventing the synthesis of essential RNA and proteins needed for bacterial growth and survival.

Rifampicin is often used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its use contributes to the identification and study of specific bacterial strains.
