Immunofluorescence studies were carried out as previously described [24] (link). Briefly, cells grown overnight on 24-well cover glasses (Menzel, 12 mm) were treated with Cy2/Cy3-labeled MOA in FCS-containing medium and fixed in 4% paraformaldehyde (PFA) at 4 °C for 10 min. Cells were washed and incubated with NH4Cl at room temperature for 15 min before being permeabilized with PBS containing 0.02% saponin and 0.2% bovine serum albumin (BSA).

Xenopus or human RPE1 immunoblotting samples were prepared with modified lysis buffer (TBS, 1% Triton X-100, and 10% glycerol with protease inhibitor). After removing fat and cellular debris, a sodium dodecyl sulfate (SDS) sample buffer with dithiothreitol (DTT) was added. Samples were loaded on SDS-polyacrylamide gels and transferred to polyvinylidene fluoride membranes (Merck Millipore, MA, USA). Membranes were incubated in blocking solution (TBS, 0.05% Tween-20 with non-fat powdered milk) for 30 min at room temperature to block non-specific binding. Immunoblotting was performed with the following antibodies at 1:2,500–3,000 dilutions for either 1 hr at room temperature or overnight at 4°C: anti-DDDD-K (Abcam, ab1162), anti-α-actin (ThermoFisher Scientific, MA1-744), anti-α-tubulin (Abcam, ab15246), anti-GJA1 (ThermoFisher Scientific, PA1-25098), anti-HA (Santa Cruz, sc-7392), anti-Rab8a (Cell Signaling, #6975), and anti-Rab11 (Cell Signaling, #5589). Secondary labeling was performed using horseradish peroxidase-conjugated anti-mouse or anti-rabbit IgG antibodies (1:3000, both ThermoFisher Scientific, 31430, 31460) for 1 hr at room temperature. Chemiluminescence was performed with SuperSignal West Dura Extended Duration Substrate (ThermoFisher Scientific, 34076), and the membranes were imaged with an iBright imaging system (FL1000, ThermoFisher Scientific).

Cells were permeabilized using ice-cold methanol for 10 min at − 20 °C to preserve microtubules. After extensive washes with PBS, cells were blocked overnight with 5% bovine serum albumin and then stained with primary antibodies and counterstained with appropriate Alexa Fluor 488-, and 555-conjugated secondary antibodies (Thermo Fisher Scientific, Rockford, IL). Coverslips were mounted with DAPI (Santa Cruz Biotechnology), and image captured with high-throughput confocal microscopy (FluoView FV1000, Olympus).

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.
