BP Fluor 405 NHS ester

BP Fluor 405 NHS Ester is a water-soluble, blue-fluorescent dye that is often used in multi-color applications, including flow cytometry and super-resolution microscopy using STORM. Its excitation is ideally suited for the 407 nm spectral line of the krypton laser or the 408 nm violet laser diode. BP Fluor 405 conjugates are pH-insensitive from pH 4 to pH 10. The NHS ester (or succinimidyl ester) is the most popular amine reactive group for labeling with the primary amines of proteins (Lys), amine-modified oligonucleotides, and other amine-containing molecules. Proteins can be labeled with BP Fluor 405 NHS Ester at high molar ratios without significant self-quenching, leading to brighter conjugates and more sensitive detection. BP Fluor 405 conjugates can also be used for the detection of abundance targets.
