Tissue Dissociation

General Description

Collagenase D is prepared fromClostridium histolyticumcultures by filtration, ammonium sulfate precipitation, dialysis, and lyophilization.

Specificity

Collagenase degrades native collagen. Clostripain, trypsin-like enzymes, and neutral proteases degrade other proteins as well.

Application

Collagenase fromC. histolyticumis widely used for the disaggregation of many types of tissues (e.g., lung, heart, muscle, bone, adipose tissue, liver, kidney, cartilage, mammary gland, placentae, blood vessels, brain, tumors) and for the preparation of single cell suspensions for the establishment of primary cell culture systems. Collagenase D is recommended when functionality and integrity of cell-surface proteins are important.
Clostridiumcollagenase from Roche has been used to prepare cells from many types of tissue, such as hepatocytes, adipocytes, pancreatic islets, epithelial cells, muscle cells, endothelial cells,etc. However, suitability of each lot of the enzyme for disruption of a particular tissue should be determined empirically.

Unit Definition

Collagenase from Roche is assayed in Wünsch units (1 μmol of product formed per minute at +25 °C with Wünsch substrate).
Frequently, collagenase activities are given in Mandl units (1 μmol leucine liberated from collagen in 5 hours at +37 °C).
Unfortunately, there is no consistent conversion factor between the two units of activity, since the Mandl unit depends, in part, on the concentration of contaminating proteases in the collagenase preparation, an indefinable variable. A purer collagenase preparation would actually give a lower specific activity in Mandl units than a crude preparation.Clostridiumpreparations typically give conversion factors of approximately 1:1800 (e.g.,a particular lot ofClostridiumcollagenase contained approximately 0.15 Wünsch U/mg and 250 Mandl U/mg).

Physical Form

Lyophilizate, nonsterile.

Preparation Note

Activator:Ca²⁺
Working concentration:0.5 - 2.5mg/mL
Storage conditions (working solution):-15 to -25°C
Roche recommends reconstituting only the amount of lyophilizate needed for immediate use. The reconstituted solution can be stored at -15 to -25°C for up to one week. Avoid repeated freezing and thawing since activity decreases after reconstitution.

Inhibitors:
Collagenase inhibitors: EDTA, EGTA, Cys, His, DTT, 2-mercaptoethanol
Collagenase is not inhibited by serum.
Clostripain inhibitors: TLCK
Trypsin inhibitors: aprotinin, trypsin inhibitor (egg white, soybean)

Enzyme activity:
Collagenase activity: >0.15 U/mg (according to Wünsch) (+25°C, 4-phenyl-azobenzyl-oxycarbonyl-Pro-Leu-Gly-Pro-D-Arg as the substrate)
Contaminating enzyme activities: trypsin, clostripain, and total proteolytic activity
Collagenase D has a normal to high collagenase activity and very low tryptic activity (usually <0.2 units/mg, BAEE as substrate).

Reconstitution

Reconstitution in any balanced salt solution (e.g.,HBSS)
