Zastosowanie
Papain from papaya latex has been used:
- in the enzyme cocktail to evaluate the efficacy of B complex vitamers liberation from nutritional yeast powder
- in the enzyme mixture for the digestion of bovine milk samples for the analysis of three vitamin B1 molecules
- as a biocatalyst for the hydrolysis of (R,S)-naproxen 2,2,2-trifluoroethyl ester in water-saturated solvents
Papain is used in dissecting solutions. It is used to produce Fab fragments of antibodies. It is used for cell dissociation since it has been shown to be more effective and less damaging with certain tissues. Papain has been used to isolate morphologically intact cortical neurons from postnatal rats. Limited papain digestion is used for structural studies of enzymes and other proteins. In addition, papain is used in red cell serology to modify the red cell surface to enhance or destroy the reactivity of many red cell antigens. Papain is useful for platelet serology studies. Papain has also been used in the enzymatic synthesis of amino acids, peptides, and other molecules. Product P3375, papain crude powder, has been used to digest fresh cartilage of dogsfish in order to isolate chondroitin sulfate.

Temporal patterning of neural progenitors is an evolutionarily conserved strategy for generating neuronal diversity. Type II neural stem cells in the Drosophila central brain produce transit-amplifying intermediate neural progenitors (INPs) that exhibit temporal patterning. However, the known temporal factors cannot
