OVERVIEW
Fluodyn™ Allophycocyanin (APC) is a water-soluble fluorescent pigment protein extracted from Spirulina thanks to an innovative proccess developped by Biosciencia®.
Allophycocyanin is a part of the photosynthetic machinery of cyanobacteria and its structure optimizes the capture and transfer of light energy. When the individual molecules are purified and isolated, they become highly fluorescent. Due to its high quantum yield and absorbance/fluorescent properties, APC offers a wide range of abilities as immunological assays, protein labelling and cell sorting.
Labeling of macromolecules with APC can provide absorbance coefficients 30-fold higher than with small synthetic fluorophores. Fluodyn™ Allophycocyanin is proposed under precipited or lyophilized form. Precipited form is provided with Quick Desalting System ready to use in few minutes. It can be conjugate with a wide range of molecules using standard reageant.
