Research Products International Corp Vancomycin Hydrochloride, 1 Gram

Vancomycin Hydrochloride is a widely used antibiotic that belongs to the glycopeptide class of antibiotics.

It is primarily effective against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE).

In the field of microbiology and research, Vancomycin Hydrochloride is used as a selective agent in culture media. It is added to growth media to inhibit the growth of Gram-positive bacteria and selectively allow the growth of Gram-negative bacteria or other microorganisms. This property makes it a valuable tool in the isolation and identification of bacteria in laboratory settings.

Research Products International Corp Minocycline Hydrochloride, 1 Gram

Minocycline Hydrochloride (HCl) is a tetracycline antibiotic. Minocycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex. This interference results in the inhibition of protein synthesis and ultimately inhibits bacterial growth.

Minocycline is effective against a wide range of bacteria, including both Gram-positive and Gram-negative bacteria. It is often used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic.
WARNING! This product can expose you to Minocycline HCl, a chemical which is known to the State of California to cause birth defects and reproductive harm. For more information go to www.P65Warnings.ca.gov.

Research Products International Corp TRIMETHOPRIM LACTATE, 250MG

Trimethoprim lactate is a combination of the antibiotic trimethoprim and organic compound lactate.

Trimethoprim, itself, is a synthetic antibacterial agent that inhibits the enzyme dihydrofolate reductase, disrupting the synthesis of tetrahydrofolic acid, which is essential for bacterial DNA and RNA synthesis. Adding lactate (a salt or ester of lactic acid) facilitates factors such as solubility, stability, bioavalability or other pharmaceutical properties.

Research Products International Corp Actinomycin D [Actinomycin C1] [Dactinomycin], 5 Milligrams

Actinomycin D, also known as Dactinomycin, is an antibiotic.

It works by binding to DNA, inhibiting both DNA and RNA synthesis. This interference with nucleic acid synthesis makes it effective against rapidly dividing cells, such as cancer cells.

Actinomycin D is used as a tool to study DNA and RNA synthesis, cell cycle progression, and cellular responses to DNA damage. Its ability to interfere with nucleic acid synthesis makes it valuable in understanding the molecular mechanisms of cell biology and cancer.

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

Research Products International Corp Spectinomycin Dihydrochloride Pentahydrate, 1 Gram

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 Penicillin G Sodium Salt [Benzyl Penicillin Sodium Salt], 100 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.

Takara Bio Anhydrotetracycline, 200 ul

Anhydrotetracycline is an antibiotic derivative of tetracycline. It is effective at lower concentrations than either tetracycline or doxycycline and is also less toxic to E. coli. It is thus a suitable antibiotic for use with the PROTet Vectors or other vectors or systems designed upon elements of the (Tn10) tet operon. 200ul
