Chemical Information Catelog Number: F01-0248 Product Name: BDP 558/568 tetrazine Molecular Formula: C26H22N7BF2OS Molecular Weight: 529.37 Purity: NMR 1H, HPLC-MS (95%) Solubility: Very soluble in DMSO and DMF Product Specification Appearance: Brown powder Excitation Maximum (nm): 561 ε, L⋅mol−1⋅cm−1: 84400 Emission Maximum (nm): 569 CF260: 0.00 CF280: 0.07 Package: 1 mg/5 mg/10 mg/25 mg/50 mg/100 mg Storage Condition: Storage: 24 months after receival at -20 °C in the Dark. Transportation: at room temperature for up to 3 weeks. Avoid prolonged exposure to light.BDP 558/568 has a high molar extinction coefficient and high quantum yield; this is a bright fluorophore and an alternative to BODIPY™ 558/568 and Cy3™ because of similar spectral properties. BDP 558/568 can be used in two-photon microscopy; it has a long excited-state lifetime, so it can be used in fluorescence polarization assay.,BDP 558/568 tetrazine is a convenient reagent for producing fluorescent conjugates of proteins, nucleic acids, and other biomolecules by tetrazine-trans-cyclooctene (TCO) ligation. This cycloaddition reaction runs relatively rapidly without metal catalysts.
