Description: Horseradish peroxidase (HRP) is isolated from horseradish roots and belongs to the ferroprotoporphyrin group of peroxidases. It is a single chain polypeptide containing four disulfide bridges. It is a glycoprotein containing 18% carbohydrate. The carbohydrate composition consists of galactose, arabinose, xylose, fucose, mannose, mannosamine, and galactosamine depending upon the specific isozyme.

Description: Elastase is prepared from porcine pancreas. It is lyophilised and water soluble. Elastase is chromatographically prepared by the method of Narayanan and Anwar. In the method, 2 times crystalline elastase is adsorbed on a column of DEAE-Sephadex A50 to separate elastase and non-specific protein components. The elastase component is further purified by chromatography on a column of CM-Cellulose using a sodium chloride gradient to elute the elastase. The latter is dialysed until chloride-free and then lyophilised. During its preparation the elastase is held below a pH of 5,5 for greater than 24 hours. Two times crystallised from the euglobin fraction of porcine pancreas by the method of Lewis et al. Does not contain trypsin or chymotrypsin.

Description: Bromelain is a glycoprotein which is a highly active thiol proteinase (non-specific cysteine protease), which splits glycine esters but not lysine esters; it is also a protein-digesting and milk-clotting enzyme. Substrates susceptible to bromelain include all of the common protein materials such as gelatin, casein, gluten, collagen, elastin, globulins an muscle fiber protein. It is a cysteine endopeptidase with broad specificity for cleavage of proteins. It may be from a stem or piece of fruit.
