Ficin from fig tree latex, CAS No.9001-33-6

CAS: 9001-33-6 Cat. No.: F755267 EC Number: 232-599-1

GRADE & PURITY saline suspension,≥1.0 units/mg protein (biuret)

Overview

Ficin from fig tree latex exists in multiple isoforms. The isoforms are prone to autolysis at varying temperature and tend to degrade during long term storage. It is a sulfhydryl protease with eight cysteine residues and is stabilized by three disulfide bridges.

Extinction Coefficient: E^1% = 21.0 (280 nm)
pI: 9.0

Application:

Ficin from fig tree latex has been used:

• in the electron paramagnetic resonance (EPR) and steady-kinetic measurements for assessing its peroxidase functionality
• for the digestion of eye tissue sections prior to immunostaining and immunofluorescence
