Research Products International Corp OXYTETRACYCLINE HCL, 5GM

Oxytetracycline Hydrochloride is a tetracycline antibiotic. Oxytetracycline 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. Additionally, it can be used to study bacterial susceptibility patterns or as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic.

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

Alkali Scientific Geldanamycin, from Streptomyces hygroscopicus, 5 Mg

Geldanamycin is a heat shock protein 90 (Hsp90) inhibitor used extensively in protein research to explore the molecular mechanisms of cell stress, protein folding, and cancer development. This 5 mg formulation, derived from Streptomyces hygroscopicus, inhibits Hsp90, leading to the destabilization and degradation of various oncogenic proteins. The compound has shown promise in clinical trials as a potential anti-cancer agent due to its ability to disrupt cellular pathways critical for tumor growth and survival. Geldanamycin is also studied in neurodegenerative disease research, where it helps elucidate the role of protein misfolding in disease progression.
