Detergents are essential for protein solubility during protein extraction and sample preparation, especially when working with hydrophobic proteins. The presence of high concentrations of detergents in protein samples can impair ELISA, IEF, protease digestion of proteins and suppress peptide ionisation when analysed by mass spectrometry.

The use of peptides for the generation of antibodies against specific peptides has become an essential tool in proteomic research. A crucial step in using peptides as antigens is their coupling to carrier proteins. Peptides are designed to be good epitopes by themselves; however they fail to elicit a strong antibody response. The reason for this is that the epitopes are able to bind to the B-cells, but are too small to contain additional motifs required to associate with class II molecules and T-cell receptors. The carrier proteins, once coupled to the peptides, provide these additional motifs and generate a strong antibody response. All three carrier proteins are also offered as activated carrier proteins, named as ActiveHOOK™.
