DESCRIPTION: Highly purified type II collagen (treated with 3M guanidine, DEAE-cellulose, and Na2HPO4)
APPLICATION: Can be used for various purposes, such as a standard for collagen analysis by SDS-gel,
substrate for MMP-1, MMP-8, and MMP-13, and as an antigen for immunizing animals for the
induction of collagen-induced arthritis (CIA) in certain species and strains of experimental
animals.
QUANTITY: 10 mg
FORM: Lyophilized powder
SOURCE: Porcine articular cartilage
MOLECULAR WEIGHT: 300 kDa
PURITY: >99% by SDS-PAGE, free of pepsin and proteoglycans
STORAGE: 4°C in the dark
STABILITY: 2 years
NOTES: Soluble in acidic buffer (maximum 4 mg/ml), but difficult to dissolve in neutral buffer. In order to
dissolve this product in a neutral buffer, first dissolve collagen in 0.01M or 0.05M acetic acid at
1-4 mg/ml and then add this collagen solution to the desired neutral buffer such as 2-10X TrisNaCl (final concentration of NaCl: 0.15-0.2M) or dialyze against 1X neutral buffer at 4°C.
NOTE 1: To avoid fibril formation under neutral conditions, keep solution on ice.
NOTE 2: The physicochemical property of type II collagen differs from type I collagen and type
II collagen dissolved in a neutral buffer does not form a stable gel incubating at 37°C. In order
to prepare a type II collagen gel, additional components such as type I collagen or other
substances may be required.
