CCzorb resins

The sterile, ready-to-use CCzorb® products of Ardena LSI are of use in isolation, purification, concentration, catalyzation and re-constitution of nutritional and pharmaceutical compounds. 

Within the CCzorb® line, resins for chromatography or batch wise use are available for hydrophobic or ionic interactions.

Description

For their use in high-quality and sensitive applications such as pharmaceutical and biological processes, CCzorb® products have been treated and purified in line with cGMP requirements to remove undesired monomeric and oligomeric compounds. After the cleaning and purification process, the resin is equilibrated in an application specific buffer solution (e.g., phosphate buffered saline solution). The resulting increased adsorption capacity of CCzorb® products leads to a higher purity of the end product, thereby minimizing losses.

For vaccine production, especially in connection with COVID-19 and Influenza vaccines, products of the CCzorb® line are advantageous for the encapsulation of mRNA into liposomes by the detergent removal technique and for the isolation and purification process of membrane proteins.

Further areas of use include water softening, polishing, chelation, acidification, neutralization, de-colorization and deodorization of (nutritional) products.

CCzorb® products are supplied in sterile, ready-to-use 2L bottles so that they can be transferred directly to a reactor, which makes the application considerably easier.

The CCzorb® product line consists of the following resins:
