The qDF set up and the theory of qDF have been described previously in detail15 (link). Here, we expended qDF to three channels (TqDF). The set up consisted of an IX71 inverted TIRF research microscope (Olympus America) with a 100 × NA 1.45 plan-apochromatic oil immersion TIRF microscopy objective and 10 mW blue (λ=488 nm), 10 mW yellow-green (λ=561 nm), and 5 mW red (λ=641 nm) diode-pumped solid-state lasers (CVI Melles Griot) as TIRF excitation light sources. Images were captured at a rate of 0.2–1 frames per second using a QV2 (Photometrics) QuadView video coupler and a 16-bit digital charge coupled device camera (Hamamatsu C10600-10B ORCA-R2). The laser shutters and camera were controlled with the SlideBook5.5 software (Intelligent Imaging Innovations). The absorption and emission peaks of the fluorochromes used in this study were, respectively, 493 and 518 nm for DL488, 562 and 576 nm for DL550, 649 and 666 nm for CellMask DeepRed. There was no bleed-through between channels. A TIRF incidence angle of θ=70° was used for all three lasers in all TqDF experiments.

The qDF setup and the theory of qDF have been described previously in detail (Sundd et al., 2010 (link), 2011 (link); Wen et al., 2020 (link)). The setup was based on an IX71 inverted TIRF research microscope (Olympus) equipped with a 100x NA 1.45 plan-apochromatic oil immersion TIRFM objective and 30 mW 488 nm, 20 mW 561 nm and 5 mW 641 nm diode-pumped-solid-state lasers (CVI Melles Griot) as TIRF excitation light sources. A TIRF incidence angle of 70°was used for all three lasers in all qDF experiments. Images were captured at an interval of every 1–2 s using a 16-bit digital CCD camera (Hamamatsu C10600–10B ORCA-R2). The laser shutters and camera were controlled with the SlideBook5.5 software (Intelligent Imaging Innovations Inc.). Fluorescence channels were separated using a beam splitter (QV2 QuadView; Photometrics) equipped with two dichroic mirrors (560 nm and 660 nm) and three emission filters (525/50 nm, 600/32 nm, and 700/75 nm).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
