Cy7 NHS ester，Cyanine7 carboxylic acid该产品由提供。 我公司生产销售的该类产品质量均为95%以上，价格便宜，长期备有现货。 Amine reactive Cy7, near infrared (NIR) fluorescent dye. NIR fluorophores can be used to take advantage of near infrared window of biological tissues. Highly increased transparency of tissues in this spectral region allows to carry out in vivo imaging. This reagent can be utilized to produce Cy7-labeled biomolecules, which can be subsequently used in various research and drug design related experiments. This particular Cy7 structure features rigidized design of central polymethyne chain. This molecular reinforcement allows to increase quantum yield by 20% compared with parent structure, increasing fluorescence brightness. This reagent requires organic co-solvent for the labeling (please see Recommended Protocols section below). Water-soluble Cy7 NHS ester is also available, and recommended for protein labeling. Appearance: dark green powder Molar weight: 682.29 Solubility: Good in organic solvents (DCM, chloroform, DMF, DMSO, MeCN, alcohols), poor in water Mass spec M+ increase: 531.3 Cy7 excitation maximum, λmaxex, nm: 750 Cy7 extinction at λmaxex 199,000 Cy7 emission maximum, λmaxfluor, nm: 773 Cy7 fluorescence quantum yield: 0.3 NMR: 95+% TLC: pure Functional testing (reaction with amine): pass Store NHS esters at -20°C in the dark.
