Research Products International Corp Bafilomycin A1, 1 Milligram

Bafilomycin A1 is a potent and selective inhibitor of the vacuolar-type H+-ATPase (V-ATPase), an enzyme responsible for maintaining acidic pH in cellular compartments such as lysosomes and endosomes.

In the life science field, Bafilomycin A1 is primarily used as a research tool to investigate the role of V-ATPase and lysosomal acidification in various cellular processes. By inhibiting V-ATPase, Bafilomycin A1 disrupts the acidification of cellular compartments, which in turn affects processes such as protein degradation, autophagy, endocytosis, and vesicular trafficking.

Bafilomycin A1 can be used to study autophagy, a cellular process involved in the degradation and recycling of cellular components. By inhibiting V-ATPase, Bafilomycin A1 blocks the final step of autophagy, preventing the fusion of autophagosomes with lysosomes and thereby inhibiting autophagic degradation.

Research Products International Corp Amikacin, 1 Gram

Amikacin is an aminoglycoside antibiotic. It is often utilized in microbiology and molecular biology laboratories and functions by inhibiting bacterial protein synthesis. Additionally, it binds to the 30S ribosomal subunit of bacteria, leading to the misreading of mRNA and ultimately preventing the synthesis of bacterial proteins. Due to its mechanism of action, amikacin is effective against a wide range of Gram-negative and some Gram-positive bacteria.

Commonly used as a selective agent in cell culture and molecular biology experiments. May be included in culture media to selectively grow cells that have been genetically modified to express resistance to this antibiotic. This is often achieved by introducing a plasmid or vector containing an amikacin resistance gene into the cells.

Research Products International Corp Cefoperazone, Sodium Salt, 5 Grams

Cefoperazone Sodium Salt is a third-generation cephalosporin antibiotic. Cefoperazone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This disruption interferes with the final stages of peptidoglycan synthesis in the bacterial cell wall, leading to structural instability and eventual cell lysis.

Cefoperazone is effective against a broad range of bacteria, both Gram-positive and Gram-negative. Cefoperazone Sodium Salt is often used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its inclusion allows for the specific growth of bacteria lacking resistance to cefoperazone.
