VWR IPTG (isopropyl-β-D-thiogalactopyranoside) ≥98%

VWR IPTG (isopropyl-β-D-thiogalactopyranoside) is a ≥98% purity biochemical reagent widely used in molecular biology and microbiology as an inducer of protein expression. IPTG is a non-metabolizable analog of lactose that specifically induces transcription from lac operon-controlled promoters, making it an essential reagent for recombinant protein production in E. coli expression systems.

Key Features

• High purity IPTG (≥98%) for reproducible results.
• White crystalline powder with stable storage properties.
• Induces lac operon for controlled protein expression in E. coli.
• Non-metabolizable inducer, ensuring sustained expression.
• Supplied in research-grade packaging (10 g, 25 g, 1 kg).
• Low impurity levels: dioxane ≤ 1 ppm, water ≤ 1%.

Specifications

Applications

• Protein expression studies in E. coli using lac promoter-controlled systems.
• Molecular cloning for recombinant protein research.
• Induction of fusion proteins (e.g., His-tag, GST-tag, MBP-tagged proteins).
• Synthetic biology and genetic engineering experiments.
• Research in biotechnology, pharmaceuticals, and academic labs.

Research Significance

• IPTG is a gold-standard reagent for inducing recombinant proteins in E. coli.
• Unlike lactose, IPTG is not degraded by cellular metabolism, ensuring constant induction and reproducible protein yields.
• Used extensively in pharmaceutical R&D for recombinant protein production, including enzymes, antibodies, and vaccine candidates.
