Japanese name: 発現誘導試薬（IPTG・オートインダクション用ラクトース）
IPTG and lactose are inducers that trigger recombinant protein expression under lac or T7 promoters, mainly in E. coli. Lactose is used in auto-induction media, which switch expression on without anyone watching the culture. For manual induction, buyers compare purity, dioxane-free grade (residual dioxane can affect cells), powder or ready-made solution, plant-derived origin, and pack size. Listed below are the tracked products, the companies that make them, and their Japanese sales channels.
