Antibody peptides

In a more modified approach, differential display proteomics can also be done with no separation of proteins. This is called the protein chip approach. In this method, a variety of bait proteins such as antibodies, peptides, or protein fragments may be immobilized in an array format on specially treated surfaces. The surface is then probed with the samples of interest. Proteins that bind to the relevant target can then be analyzed by direct MALDI readout of the bound material (Nelson, 1997 Davies et ah, 1999). Lor example, well-characterized antibodies can be used as bait. Protein samples from two different cell states are then labeled by different fluorophores, mixed together, and used as probe. In such a case, the fluorescent color acts as an indicator for any change in the abundance of the protein that remains bound to the chip (Lueking et ah, 1999). A number of technical problems would still need to be overcome before applying this technique for large-scale analysis of proteins. 

Similar to drugs, liposomes could be conjugated with antibodies, peptides and genes, among others, to expand the existing range of analytical and non-analytical applications of US.

Enhanced AS values for the antibody/peptide complexes may have been a result of the greater rotational, translational and vibrational degrees of freedom as the complexes decayed relative to the mAb 4-4-20/fluorescein complex. As in the AH argument, hydration may also be an important factor to consider. Hydration has been shown to significantly influence the free energy of binding (14).

The identification of a pathology-associated antigen and the isolation of a specific binder (antibody, peptide, small organic molecule) does not automatically yield a novel imaging agent. Indeed, a number of conditions must be fulfilled in order to obtain a successful imaging result. In part, these conditions depend on the experimental modality chosen for the in vivo imaging application.
