Aptsci offers its proprietary AptoPrepTM protein precipitation assay as user friendly kits for your cellular protein isolation needs. Aptoprecipitation (Aptamer based protein precipitation) is the technique of precipitating a protein target out of solution using an aptamer that specifically binds to that particular protein.
Most commonly encountered problems with IP approach is interference from antibody heavy and light chains that may co-migrate with relevant bands, masking important results. However aptamer as an oligonucleotide will not contribute to protein/peptide background that can interfere with subsequent analysis.
The kit provides the combined advantage of specificity and convenience of isolation/elution of a particular protein from a sample containing several thousands of different proteins.
