Research Products International Corp Cephalexin, Monohydrate, 10 Grams

Cephalexin Monohydrate is a cephalosporin antibiotic. Cephalexin, as a cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This interference disrupts the cross-linking of peptidoglycans in the bacterial cell wall, leading to structural instability and eventual cell lysis.

Cephalexin is sometimes 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 cephalexin.

Research Products International Corp Clindamycin HCl, 1 Gram

Clindamycin Hydrochloride is an antibiotic that belongs to the lincosamide class and is a semisynthetic derivative of lincomycin. It inhibits bacterial protein synthesis by binding to the 50S subunit of the bacterial ribosome, preventing the elongation of polypeptide chains. This interference disrupts bacterial growth and leads to the inhibition of protein synthesis.

Clindamycin is effective against a variety of Gram-positive bacteria, including Streptococcus, Staphylococcus, and some anaerobic bacteria.

Clindamycin hydrochloride can be used as a selective agent in culture media to isolate bacteria that are susceptible to this antibiotic. Its use contributes to the identification and study of specific bacterial strains.

Research Products International Corp Bleomycin Sulfate, 5 Milligrams

Bleomycin sulfate is an antibiotic derived from Streptomyces verticillus. It has found application in the field of cancer research and treatment. This antibiotic is a glycopeptide with DNA-cleaving properties. It is known for its ability to induce DNA strand breaks, making it effective in inhibiting the replication of cancer cells.

In research settings, bleomycin sulfate is utilized as a tool to study DNA damage and repair mechanisms. It is commonly employed in cell biology experiments to induce controlled DNA damage for the investigation of cellular responses and signaling pathways associated with DNA repair.

Research Products International Corp PLICAMYCIN [MITHRAMYCIN A], 1 MG

Plicamycin, also known as mithramycin or Mithracin, is an antineoplastic antibiotic produced by the bacterium Streptomyces plicatus. Plicamycin binds to DNA and inhibits both DNA and RNA synthesis. It accomplishes this by binding to the guanine-cytosine (GC) rich regions of DNA, preventing the transcription of genetic information into RNA. As a result, the synthesis of proteins and other essential cellular components is disrupted.

Researchers may employ plicamycin to investigate its effects on gene expression, cell cycle regulation, and apoptosis in cancer cells.

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