Allophycocyanin ("other algal blue protein"; from Greek: ἄλλος (allos) meaning "other", φύκος (phykos) meaning “alga”, and κυανός (kyanos) meaning "blue") is a protein from the light-harvesting phycobiliprotein family, along with phycocyanin, phycoerythrin and phycoerythrocyanin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble and therefore cannot exist within the membrane like carotenoids, but aggregate forming clusters that adhere to the membrane called phycobilisomes. Allophycocyanin absorbs and emits red light (650 & 660 nm max, respectively), and is readily found in Cyanobacteria (also called blue-green algae), and red algae. Phycobilin pigments have fluorescent properties that are used in immunoassay kits. In flow cytometry, it is often abbreviated APC. To be effectively used in applications such as FACS, High-Throughput Screening (HTS) and microscopy, APC needs to be chemically cross-linked.
Phycocyanin peptide and application thereof
The invention belongs to the technical field of bioactive peptides, and particularly relates to a phycocyanin peptide and application thereof in preparation of a product with functions of inhibiting PTGS2 expression and regulating an Akt / GSK3beta signal channel. According to the invention, phycocyanin is taken as a raw material, active polypeptides with specific sequences are obtained through an enzymolysis separation technology, and the amino acid sequences of the active polypeptides are respectively Leuu-Ala-Ser and Leuu-Gly-Leu. Experiments prove that the phycocyanin peptide prepared by the invention can significantly inhibit the expression of PTGS2, and can play a related regulation role by activating an Akt / GSK3beta signal channel, so that the technical blank of plant active peptide targeting PTGS2 and Akt / GSK3beta signal channels is filled, and the phycocyanin peptide can be widely applied to the development of related products for regulating the abnormal expression of PTGS2 and Akt / GSK3beta signal channels.

A method for preparing phycocyanin
This invention discloses a method for preparing phycocyanin, relating to the field of separation and purification technology. The method employs ammonium sulfate fractional crystallization for purification. The crystallization step utilizes precise control of the ammonium sulfate concentration and crystallization stirring time to optimize product purity and recovery rate. This method is simple, low-cost, easily scaled up, and can effectively purify phycocyanin. 620 / A 280 Purify food-grade raw materials of grades 1-3 to A 620 / A 280 It meets reagent-grade standards greater than 4.0 and effectively removes allophycocyanin. The crystallization process results in minimal loss of the target protein, a high overall recovery rate, and produces stable phycocyanin crystals suitable for industrial production, as well as long-term storage and transportation.
