Collagenase Animal Origin-Free

Short info

For researchers in the field of cell biology, CellSystems offers the full range of products for cell isolation and tissue dissociation. With the Worthington Biochemical Corporation enzymes and biochemicals you will maximize the yield of functionally viable, dissociated cells.

Flyer Collagenases

Collagenase derived from cultures grown in medium completely devoid of animal based components

and designed for bioprocessing applications where introductions of potential animal derived pathogens must be prevented. Levels of secondary proteases are similar to Types 1 and 2. Animal-free Collagenase is suitable for applications needing to avoid introduction of animal derived pathogens into bioprocessing procedures.

• CLSAFA is the original AFA grade designed to have collagenase and secondary proteases similar to Types 1 and 2 collagenase.

 • CLSAFB contains higher collagenase and caseinase activities than CLSAFA.

 • CLSAFC has especially low tryptic activity similar to Type 4 collagenase.  

Collagenase sampling program

Under the program, individual researchers are provided with 100 mg samples of up to three different lots of collagenase for evaluation in their own assay systems. A minimum of 3 grams of each lot will be placed on HOLD, reserved in your name. When you determine which lot performs best for you, simply specify the lot desired when ordering. Please contact us for further information.*
