Product details
Lactalbumin for microbiology and biochemistry
Lactalbumin is produced by enzymatic hydrolysis of milk whey. It consists of peptides, amino acids and carbohydrates, simple and complex.
It is used in media for culturing of bacterial cells (e.g. lactobacilli), for tissue culture, production of vaccines and in fermentation procedures.

Molar extinction coefficient: 4,4x104 L x mol-1 x cm-1 (acc. to 0,667 L x mol-1 x cm-1 for a 0,1 % solution).
BSA are proteins yielded from blood, which function as binding and transport proteins in blood circulation. Depending on the preparation process, the albumins contain different quality and quantities of metabolic products, enzymes, peptides, fatty acids, vitamines, etc. and are suitable for different applications.
