New C. difficile product and improvements

July 21, 2014

By: List Labs

List Biological Laboratories, Inc. is pleased to announce a key addition to our Clostridium difficile Toxin A and Toxin B product line. Our new product, 155L is a liquid formulation of Toxin B. This product allows for the highest activity level of any of our C.difficile offerings and the most stability.  It already shows stability for several months when stored at 2-8°C and we will continue to update.

This product is offered in a 50 µg size for $450.

We are very excited about the liquid formulation and the flexibility it will allow in the lab. It is now available from stock, and ships on Blue Ice throughout the U.S. and Canada and worldwide with special arrangements.

Clostridium difficile Toxin A
We have enjoyed tremendous success with our Toxin A. We have determined that the best activity and stability post-reconstitution (up to 2 months) is in the 100 µg size, #152C. The price for this product has been lowered from $535 to $300 based on the dramatic improvements in our yield and the substantial growth in overall sales. We are happy to pass this savings on, making it a terrific value for our C.difficile customers.

Clostridium difficile Toxin B
Products 155A and 155B have a newly formulated buffer which allows for highly active Toxin B. After reconstitution, this product is stabile for days when stored at 2-8°C and is now available from stock.

We offer a variety of Binary Toxins and Antibodies to complement your C.difficile research. We have Binary Toxins, both A and B subunit. Check our website for more information.

Bulk Product Orders
Should you have need of a substantial quantity of C.difficile in bulk, please let us know what quantity and formulation you desire. With sufficient quantity, we can often tailor to your specific needs. We generally have bulk available for all C.difficile offerings.  We also offer other types of bulk reagents for purchase.

Coming Soon-Pipeline
Clostridium difficile produces and secretes a glutamate dehydrogenase (cdGDH). This enzyme is highly conserved among different ribotypes, and antibodies to cdGDH are often included in detection kits for C. difficile infection (CDI), increasing sensitivity. While cdGDH is available recombinantly, we have isolated and purified the cdGDH from a native strain of C. difficile. In addition to the enzyme, chicken antibodies will be generated and made available soon.

We welcome your feedback on these changes and would love to hear how the new formulations and new products work for you. Please contact us with your comments and feedback.
