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.

HRP is a plant glycohemoprotein belongs to the ferroprotoporphyrin group of peroxidases. It is used in biochemistry applications such as western blots, ELISA and Immunohistochemistry. It is used to amplify a weak signal and increase detectability of a target molecule, such as a protein. HRP labeled immunoglobulins are used as probes for the demonstration of tissue antigens and in enzyme immunoassay (EIA) systems for determination of soluble and insoluble antigens.

Collagenases degrade native helical collagen fibrils. The enzyme has an important role in connective tissue metabolism and is produced by specific cells involved in repairs and remodelling processes. It is a type II enzyme that contains greater clostripain activity. It is generally used for heart, bone, muscle, thyroid, cartilage, and liver cells. Ca²⁺ is required for its activation while metal chelating agents such as cysteine, EDTA or o-phenanthroline inhibits its activity.

Beta-glucuronidases are members of the glycosidase family of enzymes that catalyse breakdown of complex carbohydrates. Human β-glucuronidase is a type of glucuronidase that catalyses hydrolysis of β-D-glucuronic acid residues from the non-reducing end of mucopolysaccharides, such as heparan sulfate. In human gut β-glucuronidase converts conjugated bilirubin to the unconjugated form for reabsorption.
