HY-D1815

Allophycocyanin 1 Publications Verification APC Dye	Fluorescent Dye	Others
Allophycocyanin (APC Dye) is a light-harvesting protein, containing strongly coupled dimers of chromophores. Allophycocyanin serve as a minimal system to examine photosynthetic energy transfer. Allophycocyanin strongly absorbs far-red light (FRL), and expresses during acclimation to low light, likely associates with chlorophyll a-containing photosystem I .

HY-D2395

B-Phycoerythrin B-PE	Fluorescent Dye	Others
B-Phycoerythrin (B-PE) is a light-harvesting pigment protein that can be isolated from the red alga Porphyridium cruentum. The absorption spectrum of B-Phycoerythrin peaks at 545 nm and 563 nm, with a shoulder at 498 nm .

HY-NP026

Spirulina C-phycocyanin C-phycocyaninfromporphyratenera	SOD Integrin	Inflammation/Immunology
Spirulina C-phycocyanin, a component of the light-harvesting phycobilisome complex in photosystem II, is a highly dominant chromoprotein in Spirulina. Spirulina C-phycocyanin can be detected by Raman spectral measurement. Spirulina C-phycocyanin has antioxidant, anti-inflammatory, antiplatelet, liver-protective and cholesterol-lowering effects .

HY-N7523

Neoxanthin	DNA/RNA Synthesis Apoptosis	Cancer
Neoxanthin is a major xanthophyll carotenoid and a precursor of the plant hormone abscisic acid in dark green leafy vegetables. Neoxanthin is a potent antioxidant and light-harvesting pigment. Neoxanthin induces apoptosis and has anticancer actions .

HY-172755

NO-Rosa5 chloride Nitric Oxide-Rosa5 chloride	NO Synthase	Others
NO-Rosa5 (chloride) is a photocontrollable NO donor. NO-Rosa5 (chloride) is made up of the fluorescent dye rosamie that functions as the light-harvesting group .

HY-N9677

Digalactosyldiacylglycerol	Herbicide	Others
Digalactosyldiacylglycerol is a membrane structure stabilizer that selectively acts on *photosystem II light-harvesting* complex II (LHCII), serving as a natural bilayer-forming lipid in plant thylakoid membranes*. Digalactosyldiacylglycerol constructs a lipid bilayer environment with monogalactosyldiacylglycerol (MGDG) in a 2:1 molar ratio, stabilizing the supramolecular structure of LHCII through interactions such as hydrogen bonding. Its core activity is maintaining thylakoid membrane stacking (grana formation) and supporting photosynthesis-related functions, while also possessing functions in light harvesting* assistance and excitation energy quenching regulation under light stress. Digalactosyldiacylglycerol can be used in research on plant photosynthesis mechanisms, thylakoid membrane structure and function regulation, as well as in the construction of artificial photosynthetic systems and the development of plant photoprotection strategies .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
