Elastase, porcine pancreas

MDL
MFCD00130998
EINECS
254-453-6

Propriétés chimiques

Forme
Lyophilized powder, MW 25000
Solubilité
Soluble in water or Tris buffer up to 2.5mg/ml. Avoid high salt concentrations (ie >50mM) if salt is necessary in the buffer. Unstable in solution at pH <3.5.

Applications

This enzyme can be used alone or in combination with other proteases for protein analysis by mass spectrometry and other applications. Elastase, is used in tissue dissociation because elastin is found in highest concentrations in the elastic fibers of connective tissues, elastase is frequently used to dissociate tissues that contain extensive intercellular fiber networks. For this purpose, it is usually used with other enzymes such as collagenase, trypsin, and chymotrypsin, membrane protein solubilization, protein sequence studies.

Notes

Minimum 3 units per mg protein. One unit cleaves one micromole of N-succinyl-L-alanyl-L-alanyl-L-alanine-p-nitroanilide per minute at 25 degrees and pH 8.0
