PRLog - Sep. 6, 2012 - MONMOUTH JUNCTION, N.J. -- MONMOUTH JUNCTION, NJ.– Cleanascite™ from Biotech Support Group 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. Cleanascite™ is an ideal sample clarification and purification reagent for physicochemical fractionation antibody purification, class-specific affinity purification of antibodies, antigen-specific affinity purification of antibodies. It is compatible with large scale antibody purification protocols. During the development process of anti-immunoglobulin E (IgE) antibodies, Cleanascite™ is required because it is a solid phase, non-ionic adsorbent and this specialty technology makes it great for initial purification. It complements other purification biotechniques such as gel filtration, dialysis, ammonium sulfate precipitation or ion exchange chromatography or hydrophobic interaction. Moreover, Cleanascite™ is the right choice for experiments in which affinity chromatography cannot be implemented or if more purity is needed. For example, protein G and protein A are not bound to IgE therefore Cleanascite™ is the right choice.

After recovery and harvest of antibodies, Cleanascite™ removes impurities during the purification process of cell debris resulting in samples which are clarified from lipids, cell debris, lipoproteins, floating fats, impurities and it extends the life of membrane and chromatographic columns. 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.

Characteristics Of Cleanascite™

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.
