Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

Chromophores of allophycocyanin and R-phycocyanin [PDF]

Biochemical Journal, 1967
The biliprotein allophycocyanin was purified from Phormidium luridum, Anabaena variabilis and Plectonema boryanum. R-phycocyanin was purified from Rhodymenia palmata. The chromophores were cleaved from the denatured protein by methanol hydrolysis. They were purified and crystallized as the dimethyl esters.

Nutraceutical properties of phycocyanin

Journal of Functional Foods, 2014
Phycocyanin (PC) is one of the main pigments of the algae Spirulina, which is used as a dietary supplement due to its high protein content. PC is a protein from the phycobiliprotein family characterized by its intense blue color and its structure consists of a protein and non-protein components known as phycocyanobilin. PC scavenges reactive oxygen and

Deep Learning–Driven Surface‐Enhanced Raman Scattering–Lateral Flow Immunoassay With Au Nanostars for High‐Accuracy Respiratory Virus Detection

Rare Metals, EarlyView.
ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Role of histamine in the inhibitory effects of phycocyanin in experimental models of allergic inflammatory response

Mediators of Inflammation, 2002
It has recently been reported that phycocyanin, a biliprotein found in the blue-green microalgae Spirulina, exerts anti-inflammatory effects in some animal models of inflammation.

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

C-Phycocyanin Suppresses the In Vitro Proliferation and Migration of Non-Small-Cell Lung Cancer Cells through Reduction of RIPK1/NF-κB Activity

Marine Drugs, 2019
Phycocyanin, derived from Spirulina platensis, is a type of natural antineoplastic marine protein. It is known that phycocyanin exerts anticancer effects on non-small-cell lung cancer (NSCLC) cells, but its underlying mechanism has not been elucidated ...
