Medchemexpress LLC 4-Nitrophenyl α-L-rhamnopyranoside | 18918-31-5 | 99.8% | 285.25 | 50 MG
4-Nitrophenyl α-L-rhamnopyranoside is a substrate commonly used in various biochemical assays to measure the activity of enzymes that hydrolyze rhamnose, such as α-L-rhamnosidase. It possesses unique chemical properties that enable its hydrolysis by these enzymes, resulting in the formation of a yellow product called p-nitrophenol. This characteristic makes it a valuable tool for detecting and quantifying rhamnohydrolase activity in biological samples or microbial cultures.

Alkali Scientific IPTG [Isopropyl β D thiogalactopyranoside], Dioxane Free, 100 Grams (Glass Bottle)
IPTG (Isopropyl β-D-Thiogalactoside) is a widely used inducer in molecular biology applications, particularly for the expression of recombinant proteins in bacterial systems. The 100g bottle provides an ample supply for large-scale experiments or ongoing research. IPTG functions by inducing gene expression in systems that utilize the lac operon, where it activates transcription without being metabolized by the host cell. This reagent is essential for protein expression studies, gene regulation experiments, and enzyme production in bacterial cultures. IPTG is commonly used in cloning, protein purification, and research on gene expression systems, helping scientists produce proteins for analysis or therapeutic use.

Alkali Scientific IPTG [Isopropyl β D thiogalactopyranoside], Dioxane Free, 400 G
Isopropyl β-D-thiogalactopyranoside (IPTG) is a molecular biology reagent used for inducing gene expression in bacterial cultures. This dioxane-free formulation provides a non-metabolizable substrate that activates the lac operon in recombinant E. coli strains carrying the lacZ gene or other inducible systems. The compound acts as a powerful inducer of gene expression, triggering the synthesis of proteins under the control of the lac promoter. IPTG is commonly used in enzyme assays, protein production, and gene expression studies, making it essential for cloning and recombinant DNA technology. This 400g bulk format is ideal for large-scale applications in molecular biology research.
