New Worthington animal free bioprocessing enzymes & collagenase sampling program

Worthington has announced two new products for nucleic acid research and bioprocessing applications; NUCxyme™ DNA/RNA Nuclease, Recombinant, Animal Free and Ribonuclease U2, Animal Free.

Animal Free Collagenases, Types AFA, AFB and AFC, and STEMxyme^® STZ1, and STZ2 collagenase/neutral protease blends are derived from cultures grown in medium completely devoid of animal-based components and designed for bioprocessing applications where introduction of potential animal derived pathogens must be prevented. Levels of secondary proteases are similar to Types 1 and 2 collagenase.

• CLSAFA is the original animal free grade designed to have collagenase and secondary proteases similar to Types 1 collagenase
• CLSAFB contains higher collagenase and caseinase activities than CLSAFA
• CLSAFC has especially low tryptic activity similar to Type 4 collagenase
• CLSAFD contains two-to-three-fold higher specific activity than CLSAFA
• Purified collagenase, code CLSAFP contains minimal secondary proteolytic activities along with high collagenase activity
• STZ1 & STZ2, 0.22μ filtered STEMxyme^® AF Collagenase/Neutral Protease (Dispase^®) blends for primary and stem cell isolation

Worthington also offers a collagenase sampling program. Under the program, individual researchers are provided with 100 mg samples of up to three different lots or types of collagenase for evaluation in their own applications.
