Chondroitinase ABC
Enzyme, Antibodies & Kits for Neuroscience and Glycoanalysis
Chondroitin Sulfate Proteoglycans (CSPGs) are involved in the inhibition of axon regeneration after various forms of damage to the Central Nervous System, including stroke and spinal cord injury. The enzyme Chondroitinase ABC (purified from Proteus vulgaris) degrades these CSPGs, and has been shown to promote functional recovery and neural regeneration in addition to its role as a tool in glycoanalysis.
Benefits
- Catalyzes the removal of Chondroitin Sulfate and Dermatan Sulfate side chains of proteoglycans
- Highly specific for glycosaminoglycan (GAG) chains without activity on core proteins, keratan sulfate chains, and heparin/heparan sulfate chains
For use in:
- In vivo & in vitro models of CNS damage/repair (perineuronal net removal and neural regeneration)
- Glycoanalysis - structure and function of proteoglycans and glycosaminoglycans (GAGs)
- Disc degeneration and discogenic low back pain (LBP) models
Chondroitinase ABC enzyme (Protease Free, BSA Free, low endotoxin)
AMSBIO’s new Chondroitinase ABC is a replacement for the protease-free Chondroitinase ABC (100332-1A) formerly supplied by Seikagaku Biobusiness Corporation (and available through AMSBIO), which was discontinued by the manufacturer in 2011 as part of their broader decision to pull out of the research reagents and glycobiology biochemicals business.
Chondroitin Sulfate Antibodies
Along with our Chondroitinase ABC, we also supply three chondroitin sulfate antibodies that recognise unsulfated (0S), 4-sulfated (4S) & 6-sulfated (6S) Chondroitin & Dermatan Sulfate, following Chondroitinase ABC digestion of proteoglycans or perineuronal nets.

Chondroitinase ABC Activity Kits
The chondroitinase assay kit is an assay for quantitative detection of chondroitinase enzyme activity in cell culture supernatants, human plasma, biological fluids and tissue samples. It is designed on the same principle as our Heparanase and Hyaluronidase Activity kits , and is available in two formats: one with enzyme as positive control, one without.
