Cleanascite™ Cited in the Preparation of Monoclonal Antibodies

By: Biotech Support Group
MONMOUTH JUNCTION, N.J. - Oct. 10, 2020 - PRLog -- Biotech Support Group reports on a book chapter describing the simplicity and efficiency of their lipid clearance sample preparation technology for the preparation and storage of monoclonal antibodies. The citation is:

Collecting and Storing Hybridoma Tissue Culture Supernatants

For most immunochemical methods, tissue culture supernatants will be the most useful source of monoclonal antibodies. The supernatants are not contaminated with high levels of other antibodies, and the concentration is high enough for most assays if used undiluted. Procedures for collecting tissue culture supernatants are described. In the Troubleshooting section, the chapter states: "Problem (Step 7): A precipitate of lipids and/or cryoproteins has formed.
Solution: This may be produced by long-term storage at 4°C. These precipitates can be removed …using Cleanascite (Biotech Support Group; X2555) for clarification."

"With the cost and complexity of producing pure monoclonal antibodies, it is essential to have methods that maintain high yields. Here is another citation for the use of Cleanascite™ for the purpose of removing lipids and maintaining high recovery of monoclonal antibodies." states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
