Alkali Scientific IPTG (Isopropyl β D thiogalactopyranoside), Dioxane Free, 50 G
IPTG (Isopropyl β-D-thiogalactopyranoside), Dioxane Free, 50g, is a molecular biology reagent widely used for inducing gene expression in bacteria, particularly in E. coli. This compound facilitates the activation of the lac operon, leading to the expression of genes controlled by the lac promoter. The 50g package size is suitable for high-throughput laboratories or researchers requiring larger quantities for repeated experiments. The dioxane-free formulation provides a safer alternative for environments sensitive to contamination by toxic solvents. IPTG is essential for protein expression systems, gene function analysis, and molecular cloning applications in research and biotechnology.

Alkali Scientific Isopropyl B D thio galactopyranoside [IPTG], Non Mammalian, Dioxane Free, 5 Grams
Isopropyl β-D-thiogalactopyranoside (IPTG), Non-Mammalian, Dioxane Free, 5g, is a highly purified molecular biology reagent used to induce gene expression in bacteria. The non-mammalian formulation ensures that the compound is free from any mammalian contamination, making it suitable for specific applications in microbial systems. IPTG induces gene expression by binding to the lac repressor and activating the lac operon, commonly used for protein production and molecular cloning. The dioxane-free composition ensures a safer alternative for sensitive experiments where toxic solvent residues may interfere with the results. Ideal for molecular biology research, recombinant protein studies, and gene expression analysis.
Gold Biotechnology Inc HEPES, Free Acid 500 g
HEPES is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.8 – 8.2. HEPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions. It is commonly used in cell culture media and as an ampholytic separator to create a pH gradient in isoelectric focusing. HEPES interferes with reactions between DNA and restriction enzymes to a lesser extent than similar buffers with less substituted amine groups, such as Tris. This lack of interference occurs because steric hindrance of the protonated tertiary amine in HEPES shields the negative charge of DNA to a lesser extent than less substituted buffers. This buffer is capable of forming radicals and is therefore not suitable for redox reactions. It is suitable for use in the bicinchoninic acid (BCA) assay.
