Molecular biology relies heavily on a wide range of reagents and tools to explore genetic processes and manipulate biological systems. Luciferin, IPTG, and Competent Cells are fundamental products used in various molecular biology applications. Luciferin, a bioluminescent substrate, is essential for reporter assays and gene expression studies, enabling real-time detection of biological activity. IPTG (Isopropyl β-D-1-thiogalactopyranoside) is a key inducer used to trigger gene expression in bacterial systems, particularly in the lac operon system, facilitating protein production. Competent Cells, treated bacterial cells capable of taking up foreign DNA, are indispensable for genetic transformation, cloning, and the creation of recombinant DNA. These products are integral to advancing molecular biology research and experimentation.
