Research Products International Corp Kanamycin Monosulfate [Kanamycin A], 25 Grams

Kanamycin A is a broad-spectrum aminoglycoside antibiotic derived from Streptomyces kanamyceticus. It is widely used in microbiology, molecular biology, and genetic engineering as a selective agent. Commonly added to culture media, Kanamycin A inhibits the growth of non-resistant bacteria, allowing selection of cells carrying a kanamycin resistance gene. It is frequently used in recombinant DNA experiments and as a selectable marker in plasmids and other vectors. Researchers also use it to study bacterial resistance and antimicrobial efficacy. Its potency and low toxicity make it valuable in protein expression and genetic studies.

Alkali Scientific Amphotericin B, 100 Mg

Amphotericin B is a polyene antifungal agent widely used in microbiology and cell culture applications to prevent and control fungal contamination. It functions by binding to ergosterol in fungal cell membranes, creating pores that disrupt membrane integrity and lead to cell death. This mechanism makes it highly effective against a broad range of yeasts and molds. In laboratory settings, Amphotericin B is commonly added to culture media to maintain sterile conditions during experiments. It is also used in research involving fungal pathogens, antifungal susceptibility testing, and studies focused on membrane biology and antifungal drug development.
