BP Fluor 430 NHS ester

BP Fluor 430 NHS Ester is a water-soluble green fluorescent dye commonly utilized in multicolor applications such as flow cytometry and super-resolution microscopy employing STORM. It is optimally excited by the krypton laser's 407 nm line or a 408 nm violet laser diode. BP Fluor 405 conjugates remain pH insensitive from pH 4 to pH 10. The NHS Ester (or succinimidyl ester) is most frequently used as an amine-reactive group for labeling primary amines in proteins (Lys), amine-modified oligonucleotides, and other amine-containing molecules. Proteins can be labeled with BP Fluor 430 NHS Ester at high molar ratios without significant self-quenching, resulting in brighter conjugates and more sensitive detection.
