Peptide enzyme Conjugation

Peptides are a kind of promising molecules with the potential protein-anchoring/modulating property, due to their large chemical diversity and the existence of well-established methods for library synthesis. There is a growing realization that it is possible to create synthetic structures with affinities and specificities comparable to natural antibodies, by using peptides as building blocks.

Enzymes often detect proteins by direct or indirect antibody detection strategies or as nucleic acid hybridization probes in sensitive assays. Reported enzyme molecules are widely used in biology due to their special properties. Although the detection of fluorescent and luminescent tags has made great progress, but enzyme conjugates can detect immune complexes by visual or spectrophotometry as sensitive probes. Enzyme labels provide the best overall performance, high sensitivity, low background, and can achieve fast detection.

Horseradish peroxidase and alkaline phosphatase are commonly used to linked to peptides or proteins.

For the detection of proteins, horseradish peroxidase (HRP) substrates are designed to produce signals for chromogenic, chemiluminescent or fluorescent oxidation. HPR has a molecular weight of 40,000. This molecular weight is lower than other enzyme conjugates, allowing for greater tissue and cell permeability and reducing the possibility of interfering with protein coupling.

Synthetic peptide-alkaline phosphatase conjugates, which was developed with alkaline phosphatase (AP) as the detector enzyme, permits epitopespecific analysis of antibody responses in experimentally or clinically derived lymphoid tissue.
