Description
Collagenase cleaves peptide bonds in native, triple-helical collagen. The substrate, collagen, is the major fibrous component of animal extracellular connective tissue: skin, tendon, blood vessels, bone, etc. True collagenase may cleave simultaneously across all three chains or attack a single strand.
Activator: Ca 2+
Inhibitor: EDTA/EGTA (no inactivation by serum)
pH-optimum: 7.0 - 8.0
Collagenase 2, powder
Activity (Wünsch): ≥ 0.1 Units*/mg
*(One unit catalyses the hydrolysis of 1 µmole 4-phenylazobenzyloxycarbonyl-L-prolyl-L-leucyl-glycyl-L-prolyl-D-arginine per minute at +25°C, pH 7.1)
Reconstitution: In water (100 mg/ml)
Collagenase 2, solution
Concentration: 2 Units*/ml
Shelf Life and Storage
Powder: The lyophilisat is stable for up to 2 years at +2 °C to +8 °C
Solution: The reconstituted solution is stable for 2 years at ≤-15 °C
Instructions for cell detachment
Use Collagenase 2 in the same manner that trypsin EDTA solutions are used to detach adherent cells from surfaces. Always handle cells with standard aseptic techniques if the cells are subcultured or propagated further.
- Wash the cells with a small volume of sterile PBS. Remove wash liquid.
- Add appropriate amount of Collagenase 2.
- Return the culture to +37°C incubator and allow cells to detach for about 5-20 minutes.
- Count cells and passage as usual.
Instructions for cell dissociation
- Incubation of tissue with an appropriate amount of Collagenase 2 in culture medium.
- Return to the CO2-incubator for 1-48 hours (depending on the type of tissue).
- Remove the dissociated cells from the tissue.
- Cultivate the cells as usual.
For in vitro laboratory use or further manufacturing only. Not for human use.
