Apexbio Technology LLC Filipin III, 1mg. Cas: 480-49-9 MFCD: MFCD30742956. cholesterol-binding, fluorescing antibiotic used for the detection of lipoproteins

Filipin is the collective name given to four isomeric polyene macrolides isolated from cultures of S. filipinensis; Filipin III is the predominant isomer and the one used in most studies. Filipin binds to cholesterol in membranes, forming ultrastructural aggregates and complexes which can be visualized by freeze-fracture electron microscopy [1,2]. The binding of cholesterol also decreases the intrinsic fluorescence of Filipin, and this property has also been used to detect cholesterol in membrane fractions. Other sizes are available.

Research Products International Corp Geldanamycin 1 MG

Geldanamycin is a naturally occurring antibiotic derived from the bacterium Streptomyces hygroscopicus. It has gained significance due to its role as an inhibitor of heat shock protein 90 (Hsp90), a molecular chaperone involved in protein folding and stabilization.

Geldanamycin is often used as a research tool to study cellular processes that are dependent on Hsp90. By inhibiting Hsp90, geldanamycin affects the stability and function of various client proteins associated with cell signaling, growth, and survival.

Researchers use geldanamycin to investigate the role of Hsp90 in the context of cancer, as many oncoproteins require Hsp90 for proper folding and stability.

Gold Biotechnology Inc Carbenicillin (Disodium), USP Grade 100 g

Carbenicillin is a member of the penicillin β-lactam antibiotics. However, unlike most β-lactams, carbenicillin disodium is limited to primarily gram-negative bacteria including Pseudomonas aeruginosa and common enteric species. It can be used in selection protocols and is often preferred over ampicillin due to its increased stability. This allows for less contamination of unwanted bacterial colonies. In addition, carbenicillin has been used to regulate bacterial growth in plants, yielding low regeneration frequencies. It can be used in genetic transformation applications to select for AmpR transformed cells.

Research Products International Corp Blasticidin S Hydrochloride Powder, 1 G

Blasticidin S hydrochloride powder is a commonly used antibiotic in the life science marketplace. It is primarily employed as a selective agent in cell culture systems and molecular biology applications.

Blasticidin S is derived from Streptomyces griseochromogenes and is effective against a wide range of organisms, including bacteria, yeast, fungi, and certain higher eukaryotic cells. It works by inhibiting protein synthesis in cells, specifically targeting the 80S ribosome and interfering with the peptidyl transferase activity.

In the life science marketplace, Blasticidin S hydrochloride powder is frequently used in cell culture research and genetic engineering. It is added to growth media to select for cells that have successfully incorporated a Blasticidin S resistance gene, typically as part of a recombinant DNA construct or plasmid vector.

Research Products International Corp Chloramphenicol, 100 Grams

Chloramphenicol is a phenicol-class antibiotic effective against a broad range of Gram-positive and Gram-negative bacteria. Commonly used in microbiology, cell culture, molecular biology, and genetic engineering, it serves as a selective agent by inhibiting bacterial protein synthesis via the 50S ribosomal subunit. It allows the growth of cells carrying the Chloramphenicol resistance gene while inhibiting non-transformed cells. It is used to maintain plasmids and vectors with the resistance gene and supports studies on gene expression and protein synthesis.
