Lipid Removal & Clarification


Cleanascite™

Lipid Adsorption & Clarification

  • Effectively replaces chlorinated/fluorinated hydrocarbons (eg. freon)
  • Workflows for antibodies, proteins, nucleic acids, proteoglycans, and most serum analytes
  • A high binding capacity for lipids with minimal cross-reactivity with proteins and nucleic acids
  • Suitable alternative to StatSpin LipoClear
  • Ideal for clarifying ascites, serum, cell & tissue culture, bile and organ homogenates
  • Clarifies saliva and fecal components
  • Exquisite selectivity profile including extracellular vesicle and exosome clearance
  • Extends the life of membrane and chromatographic columns.
  • Enrichment of delipidated tissue samples
  • For downstream processing of large-scale therapeutic proteins, enzymes and monoclonal antibodies.

Cleanascite™ is derived through a proprietary formulation of metallic oxide derivatives. Unlike other metallic oxides, Cleanascite™ does not have significant protein binding making its selectivity profile for lipids unique in the bio-research products industry. As a result, it is ideal to clear lipid-associated matrix effects from human sera, bile, ascites, and other high lipid content sample types.

Key References

Plasma/Serum Protein Biomarkers

The authors aimed at simultaneously measuring intact insulin and proinsulin derived C-peptide, to help predict development of diabetes mellitus, as well as in differential diagnosis in cases of hypoglycemia. Cleanascite™ is shown both to improve LC-MS measurements, and validated in accordance with CLIA ’88 guidelines. { doi: 10.1016/j.cca.2016.01.019 }

Vaccine Development

To evaluate immunogenic response to a vaccine candidate, it is necessary to measure the antibodies from sera; a sample with a diverse lipid profile. In this citation, Cleanascite™ was used in a toxin neutralizing assay to evaluate the influence of cholesterol dependency, on a candidate protein pneumococcal vaccine. { doi: 10.1016/j.vaccine.2012.11.005 }

Bile Proteomics

The authors report methods to overcome the biological variability of analyzing a high number of bile samples. They concluded that delipidation yielded a considerable number of complementary protein identifications and that Cleanascite™ treatment was indispensable for in-solution digestion methods. { http://dx.doi.org/10.1016/j.jprot.2016.11.021 }

Ascites Monoclonal Antibodies

The researchers determined the role of complement on MAb-mediated protection for four mice Ig subclasses. After centrifugation of ascetic fluid, Cleanascite™ protocol was implemented to remove lipids. { doi: 10.1128/IAI.70.5.2598-2604.2002 }

Cellular Response Applications

Cleanascite™ LX

For Lipemic Serum/Plasma Clarification

  • Effectively replaces chlorinated/fluorinated hydrocarbons (eg. freon)
  • Based on solid-phase referenced in over 70 publications in varied applications
  • Under investigation as alternative to LipoClear for lipemic serum/

Protocol

Cleanascite™ LX is supplied as an aqueous suspension of non-ionic adsorbent in DI water, pH 8.0. After centrifugation, the pellet is 1/2 of the total volume and the supernatant is 1/2 of the total volume.

  1. Resuspend CleanasciteTM LX by gentle shaking. Excessive shaking may cause foaming. It should be completely resuspended prior to use.
  2. Add CleanasciteTM LX to the sample at minimum 1:3 (or alternative higher) ratio. Mix the sample by gentle shaking for 20 minutes.
  3. Micro-centrifuge sample at 8,000 rpm’s (5,000xg) for 10 minutes.
  4. Carefully aspirate supernatant for analysis.

Optimization. Different sample volumes are easily scaled. Volume ratio can be adjusted up or down as required to remove the amount of impurities present.
