Collagenase Sampling Program Overview
The lot-to-lot variation which is typical of partially purified enzyme preparations such as Worthington collagenase Types 1-7 and Animal Free CLSAF Types A, B and C makes it important to pre-test a particular lot of enzyme you are planning to use in certain applications. Many years ago we found that the most practical approach for the researcher is to pre-sample several different lots of collagenase at a time and select the best of the group for their specific use. As the world's leading manufacturer of collagenase, Worthington is able to offer the greatest number of different lots at any given time and recommend specific lots for most applications.
There is no charge for participating in the 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. A period of 60 days is allowed for your evaluation of these samples. 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. The only requirement, once a suitable lot of collagenase is found, is that you purchase a minimum of 3 grams of the material.
