Alkali Scientific Radicicol [Humicola Fuscoatra], 5 Mg
Radicicol is a potent inhibitor of the heat shock protein 90 (Hsp90), a chaperone protein that plays a critical role in stabilizing proteins involved in cell signaling, proliferation, and survival. This 5mg powder form is used in laboratory research to study the effects of Hsp90 inhibition on cellular processes, particularly in cancer research and fungal infections. Radicicol’s ability to destabilize client proteins makes it a valuable tool for understanding the molecular mechanisms of disease and for evaluating potential treatments. This research-grade powder is widely used in cell-based assays to study protein folding, cellular stress responses, and therapeutic targets in oncology and microbiology.
Alkali Scientific Amikacin, 25 G
Amikacin is a potent aminoglycoside antibiotic used in laboratory and research environments to inhibit bacterial growth in cell culture and microbiological applications. It acts by interfering with protein synthesis through binding to the 30S ribosomal subunit, resulting in bactericidal activity. This compound is especially effective against Gram negative bacteria and is often selected when resistance to other antibiotics is present. The reagent is commonly incorporated into culture media to maintain sterility and reduce contamination risks during experimental procedures. It is widely used in molecular biology, microbiology, and pharmaceutical laboratories requiring consistent antimicrobial performance.
