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 Puromycin, 1 G

Puromycin Dihydrochloride is a potent antibiotic. It is an amino nucleoside antibiotic that mimics the 3'-end of aminoacyl-tRNA. It enters the ribosomal A site during translation, causing premature chain termination and inhibiting protein synthesis. Puromycin is incorporated into growing polypeptide chains, leading to the release of incomplete and nonfunctional peptides.

Widely used as a tool in cell biology to study protein synthesis and investigate translation processes. Its ability to terminate protein synthesis at the ribosome makes it valuable for various applications, including pulse-chase experiments and the analysis of nascent peptides. Puromycin resistance genes are often used as selectable markers in genetic engineering. Cells expressing the resistance gene can survive and proliferate in the presence of Puromycin, allowing for the selection of transfected or transduced cells.
