Flamma® 675 NHS ester

Product description: Chemical. Formula: C47H51N3O16S4. MW: 1042.18. Synthetic. Flamma®675 is bright and stable near-infrared (NIR) fluorescent dye that features high water solubility and low toxicity. It has a similar optical spectrum to Alexa Fluor®680, Cy5.5, DyLight®680, IRDye®680LT. Near-infrared fluorescent dye is mainly used for In-Vivo Imaging in drug delivery and tumor research, as it is highly permeable to  biological tissue. Flamma®675 NHS ester is a product that has the most representative NHS ester reactive group for labeling amine. Because it rapidly and high-specifically reacts to Primary amine (-NH2), it can label Protein containing amine (-NH2), Antibody and Amine-modified Oligonucleotide in a short time period. Excitation ? Emission (nm): 675 / 691 nm. Spectrally similar dyes: Alexa Fluor®680, Cy®5.5, DyLight®680, CF™680, IRDye®680LT. Extinction coefficient: 220,000 cm-1M-1. CF280: 0.09.
