B-Phycoerythrin Labeling Kit-NH2 is primarily used for the preparation of B-phycoerythrin-labeled antibody for immunostaining and cellular proteins for tracing· NH2-Reactive B-Phycoerythrin, a component of this kit, has succinimidyl group (NHS), and can easily make a covalent bond with amino groups of IgG or other proteins without any activation process· Filtration Tube included in this kit is used for removing small molecules in the sample protein such as Tris buffer and amine compounds that interfere with the assay or labeling reaction· The maximum excitation and emission wavelengths of the B-phycoerythrin-labeled proteins are 564 nm and 575 nm, respectively· This kit contains all of the necessary reagents for labeling, including the storage buffer for conjugates·
