Application

Phycobiliprotein exhibiting exceptional absorbance and fluorescence characteristics due to a lack of susceptibility to internal and external fluorescence quenching. Ideal for highly sensitive studies in flow cytometry and immunoassays.

Biochem/physiol Actions

Allophycocyanin is a pigment which allows the energy trapped by phycobiliproteins to be transferred to the chloroplast lamellae.

Biotechnological applications of protein complexes require detailed information about their structure and composition, which can be challenging to obtain for proteins from natural sources. Prominent examples are the ring-shaped phycoerythrin (PE) and phycocyanin (PC) complexes isolated from the light-harvesting antennae

How did primitive living cells originate? The formation of early cells, which were probably solute-filled vesicles capable of performing a rudimentary metabolism (and possibly self-reproduction), is still one of the big unsolved questions in origin of life. We have recently
