β‑Lactoglobulin A is a high‑purity functional whey protein derived from bovine milk. As a core active component of the whey‑protein family, it features a highly conserved molecular conformation and excellent physiological activity, making it an important tool for protein‑function research, development of nutrient delivery systems, and cutting‑edge exploration in biomedicine.
This product is a white to off‑white lyophilized powder with a molecular weight of approximately 18 kDa. Subjected to strict quality‑control testing, it has a protein content (dry weight) ≥ 93 %, HPLC purity ≥ 95 %, and moisture content ≤ 6 %, ensuring batch‑to‑batch stability and experimental reproducibility.
Rich in essential amino acids and branched‑chain amino acids, this protein exhibits outstanding solubility, emulsifying properties, gelling properties, and unique lipid‑binding capacity. It can efficiently bind hydrophobic nutrients such as fatty acids and fat‑soluble vitamins. It is applicable to a wide range of research scenarios, including nutrient‑carrier design, protein‑protein interaction analysis, studies on thermal stability and gelling behavior, and construction of simulated dairy‑product systems.
The product is preserved by lyophilization. It is recommended to store at 2–8 °C with a shelf life of 3 years.
This product is for research use only. It is not intended for clinical diagnosis or therapeutic applications.
