MONMOUTH JUNCTION, NJ.– Inventors Iwakura Yoichiro, Kakuta Shigeru and Suzuki, Shunsuke and assignee The University of Tokyo published United States Patent Application 20130011413 titled, Method and Pharmaceutical Composition for Treatment of Intestinal Disease. The patient details a method for using interleukin-related substances like an IL-17F inhibitor typified by an anti-IL-17F antibody to treat intestinal disease such as colon polyps or colorectal cancer. The patent cites Cleanascite™ from Biotech Support Group in a method for the selection of neutralizing antibodies to mouse IL-17F and IL-17A.

Neutralizing antibodies anti-IL-17F antibody and anti-IL-17A antibodies selected were cultured in serum-free medium and from the supernatant purified antibody was developed. The hybridoma culture supernatant was recovered periodically and a one fourth quantity of Cleanascite (registered trademark) (Biotech Support Group, LLC) was added to the recovered culture supernatant. Next at room temperature the samples were shaked for 10 minutes followed by centrifugation at 2000rpm to recover the supernatant. Subsequently, filtering, purification, elution, dialysis, filter sterilizing was followed on the samples and protein concentration and the degree of purification was confirmed.

Characteristics Of Cleanascite™ Lipid Removal Reagent and Clarification

• A high binding capacity for lipids with minimal cross-reactivity with proteins
• Effectively replaces chlorinated/fluorinated hydrocarbons (eg. freon) and it is environmentally friendly.
• Helps purify antibodies, recombinant proteins, nucleic acids, proteoglycans
• Ideal for clarifying ascites, serum, cell & tissue culture, bile and organ homogenates
• Clarifies saliva and fecal components
• Very low protein binding
• Does not bind to DNA, RNA, enzymes and proteins
• Leaves glycoproteins, antibodies, nucleic acids, hemoglobin, proteoglycans, nucleic acids, serum components(such as hormones, nutrients, globulins, clotting factors, transport proteins) alone
• Extends the life of membrane and chromatographic columns.
• Enrichment of delipidated tissue samples
• Ideal for delipidation treatments for downstream processing of large-scale therapeutic proteins, enzymes and monclonal antibodies.

Cleanascite™ selectively removes lipids, cell debris, lipoproteins, floating fats, impurities from cohn paste, transgenic milk, egg yolk and biological samples for pretreatment of samples prior to purification. The reagent is a solid-phase, non-ionic adsorbent supplied as a suspension in saline, ready for use. Simply add, centrifuge and/or filter. The clarified supernatant is ready for subsequent downstream processing or analysis.
