Invitrogen Qdot 705 probe is an excellent near-IR–fluorescent label with outstanding brightness and photostability for imaging and flow cytometry applications. With an emission maximum of ~705 nm, Qdot 705 probe can be excited using a laser line from 350 nm up to 633 nm or a standard Cy5.5 filter. Optimum imaging results with brighter signals are achieved with a Qdot 705 filter or light cube.

Organic fluorophores and Qdot probes can be readily combined in multiplexed flow cytometry or imaging studies. Longer-wavelength Qdot probes are also well-suited for multiplexed western blots.

We offer Qdot 705 probe conjugated to a variety of antibodies, peptides, and proteins, optimized for cellular labeling and detection. In addition, reactive dye forms and antibody labeling kits are available to allow you to generate your own antibody conjugates or probes.

Experimental data using Qdot 705 probe
Flow histogram overlay plot of unstained (gray line) vs. Qdot 705-stained HLA-DR (black line)
Flow cytometry analysis of human lymphocytes using Qdot 705 antibody conjugate. Histogram overlay plot of gated human lymphocytes, the black line represents cells labeled with mouse anti-human HLA-DR Monoclonal Antibody (TU36), Qdot 705 and the gray line represents unstained cells. Samples were acquired and analyzed using 405 nm excitation and a 695/40 band pass emission filter using the Attune Acoustic Cytometer Blue/Violet option.
