I7403 Merck

L-Isoleucine is an essential branched-chain amino acid (BCAA) produced from non-animal sources. It is a critical component in cell culture media, pharmaceutical manufacturing, and protein research.

Add to bag

L-Isoleucine (I7403) is a high-purity crystalline amino acid that meets the stringent requirements of the European Pharmacopoeia (EP), Japanese Pharmacopoeia (JP), and United States Pharmacopeia (USP). As an isomer of leucine, it is essential for hemoglobin synthesis and the regulation of blood sugar and energy levels. This product is derived from a non-animal source, ensuring suitability for animal-free manufacturing processes. It is rigorously tested for endotoxins to ensure safe and reliable use in mammalian cell culture applications.

Advantages

  • Non-animal source: Ideal for chemically defined and animal-free cell culture media.
  • Pharmacopoeia Compliance: Meets current EP, JP, and USP standards for pharmaceutical grade materials.
  • Cell Culture Verified: Tested for endotoxins and performance in cell culture systems.
  • High Purity: Guaranteed assay range of 98.5–101.0% (dry basis).
  • Metabolic Essentiality: Key branched-chain amino acid for protein synthesis and nitrogen balance.
