Proteins

Aalto Scientific has been extracting and purifying enzymes and proteins from human sources (plasma, serum, urine and tissue) since 1979. We were the first commercial source of human Creatine Kinase isoenzymes (MM, MB and BB), which aided in the industry’s development of immunoassays for CK-MB. Today, Aalto offers a complete line of clinically significant human proteins and hormones in a variety of purity levels suitable for either control sera manufacturing or antibody development.

Alpha-Amylase

Alpha-amylase is an oligosaccharide endoglycosidase, an enzyme that cleaves an internal glycosidic bond within a  poly or oligosaccharide. In the case of alpha-amylase, 1,4 linkage between two glucose moieties, cleaving the C-O bond between the C1 carbon and the oxygen, is random.
