iFluor(R) 830 succinimidyl ester

In vivo fluorescence imaging uses a sensitive camera to detect the fluorescence emission from fluorophores in whole-body living small animals. Fluorophores with long emissions at the infrared (IR) region are generally preferred to overcome photon attenuation in living tissue. Recent advances in imaging strategies and reporter techniques for in vivo fluorescence imaging include novel approaches to improve the specificity and affinity of the probes and to modulate and amplify the signal at target sites for enhanced sensitivity. Further developments aim to achieve high-resolution, multimodality, and lifetime-based in vivo fluorescence imaging. Our iFluor(R) 830 is designed to label proteins and other biomolecules with infrared fluorescence. Conjugates prepared with iFluor(R) 830 have excitation and emission maxima in the IR range. iFluor(R) 830 dye emission is a unique color for spectrum flow cytometry as it is well separated from commonly used far-red fluorophores such as Cy5, Cy7, or allophycocyanin (APC), facilitating multicolor analysis. This fluorophore is also useful for small animal in vivo imaging applications or other imaging applications requiring IR detection. iFluor(R) 830 succinimidyl ester is amine-reactive and can be readily used to conjugate amine-containing biomolecules, particularly antibodies.
