Flamma® 774 NHS ester

Product description: Chemical. MW: 1026.14. Synthetic. Flamma®774 is a bright and stable near-infrared fluorescent dye that emits the longest range of fluorescence among Flamma®Fluors products. It features high water solubility and low toxicity and has a similar optical spectrum to Alexa Fluor®790, IRDye®800CW. 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®774 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): 774 / 806 nm. Spectrally similar dyes: Cy®7.5, CF™770. Extinction coefficient: 200,000 cm-1M-1. CF280: 0.10.
