Made from Carica papaya.
Stock solution: 10 mg/ml in water

A non-specific endopeptidase from Papaya latex. Has a very wide substrate range and cleaves proteins more efficiently than trypsin, for example. Is capable of not only hydrolysing peptide bonds, but also acts effectively as an esterase and thiol-esterase.

Product details



Papain >30 000 USP-U/mg, for biochemistry

A non-specific endopeptidase from Papaya latex. Has a very wide substrate range and cleaves proteins more efficiently than trypsin, for example. Is capable of not only hydrolysing peptide bonds, but also acts effectively as an esterase and thiol-esterase.


Unit definition

30.000 USP (Casein) Units is approx. 2 FIP-Units (BAEE-Units). One USP Unit of Papain activity releases the equivalent of 1 µg tyrosine form a specified casein substrate under assay conditions specified by the USP.


Directions for use

Working concentration: Dilution immediately before application in a buffer with approx. 5 mM L-Cysteine
pH optimum: 6.0
Temperature optimum: 65 °C
Activation and stabilization: EDTA, Cysteine and Dimercaptopropanol. DTT may be added in orderto increase activity.

General information

Enzyme: a neoclassical, Greek artificial word ενζυμου, énzymon, derived from εν-, en- (in-) and ζυμη, zýmé (yeast, sourdough, archaic)
Ferments: comes from the Latin fermentum (ferments, sourdough)

There are six classes in which all enzymes are classified according to the particular reaction they catalyse:

Oxidoreductases (catalyse redox reactions)

Transferases (transfer functional groups among substrates)

Hydrolases (cleave bonds via addition of water)

Lyases/Synthases (cleave or synthesise complex products out of basic substrates without cleavage of ATP)

Isomerases (transform chemical isomers)

Ligases/Synthetases (cleave or synthesise complex products out of basic substrates via cleavage of ATP)
