Product Description

Collagenase consists of a blend of enzymes including collagenase, caseinase, clostripain and trypsin designed to effectively hydrolyze collagen and dissociate tissues.  Various collagenase products have been evaluated specifically for use with Advanced BioMatrix’ s collagen products.  This product is offered to improve the viability and functionality of isolated cells from the digested collagen gels.

Collagenase is provided as a lyophilized, sterile powder in a 50 mg package size.   After reconstitution, the product is ready-to-use.

  1. Use these recommendations as guidelines to determine the optimal gel dissociation procedure for your culture system.
  2. Reconstitute the lyophilized collagenase powder (50 mg) in phosphate buffered saline or other pH neutral medium. A typical concentration of 1 mg/ml may be used.
  3. Aspirate the culture medium from the collagen gel.
  4. Wash the collagen gel 2X with pre-warmed PBS or other pH neutral medium to remove culture medium which could inhibit the degradation of collagen.
  5. Add appropriate amount of collagenase solution (one gel volume should be sufficient). For example: For 24 well plates, containing 0.5 ml of gel, add 0.5 ml of collagenase solution.
  6. Transfer to a 37ºC incubator for 30-60 minutes. To facilitate the faster dissociation of the collagen gel, the gel and collagenase solution can be pipetted up and down using a large bore pipette tip.
  7. Incubate additional 30-60 minutes at 37°C, if necessary, to complete the digestion of the gel. If required, pipette the gel/cell mixture every 15 minutes. Note: Thicker gels or gels containing higher concentration of cells may require more time.
  8. Once the gel is fully digested, add an equal volume of complete culture medium to the gel/cell mixture and then collect the cells.
  9. Rinse the culture vessel collecting any residual cells.
  10. Centrifuge the cell suspension at 250 x g for 5 minutes at room temperature.
  11. Carefully aspirate the supernatant, and resuspend the cell pellet in 0.5 -1 ml of fresh medium.
  12. Determine cell count and viability using a hemocytometer and Trypan Blue.

Product Q & A

Yes.

There are sufficient levels of divalent cations in the lyophilized collagenase powder to achieve full enzymatic activity. Therefore, solubilizing the lyophilized collagen powder in medium or a phosphate buffered solution without divalent cations is recommended per the Directions for Use.

Collagenase is most stable in the lyophilized form stored at 2 to 10°C.  After reconstitution, it is recommended that any remaining solubilized collagenase be aliquoted into desired volumes and then frozen at < -20°C  for up to 1 to 2 months.  Repeat freezing and thawing is not recommended.
