Protein – Protein Coupling


Horseradish Peroxidase, Alkaline Phosphatase and other signal-generating enzymes are widely utilized as detection components in enzyme linked immunoadsorbant assay systems (ELISA).

Conjugation services are available from emp BIOTECH for these and other enzymes to antibodies or any other type of protein, resin or carrier substances.


Phycobiliproteins are fluorescent proteins functioning as components in the photosynthetic apparatus of eukaryotic cells, blue-green algae and cyanobacteria. Due to the presence of multiple fluorescent groups in each protein, conjugates of these molecules form extraordinarily luminescent probes.

Synthesis services for customized Phycobiliprotein tandem conjugates and coupling of other proteins are offered by emp BIOTECH.

Purification of conjugates by dialysis, GFC-HPLC or FPLC is available upon request.
