Cell Morphology Imaging in Acute Brain Slices

Check if the same lab product or an alternative is used in the 5 most similar protocols
For screening cells morphology and checking cell localization in acute brain slices we used a widefield infrared illumination system. This consisted of an IR-LED source (M780L2, Thorlabs) installed at the rear port of a SliceScope Scientifica microscope, an orientable blocking element to create oblique illumination and a condenser focusing the light on the sample. IR light transmitted through the sample was collected with an IR antireflection coated water-immersion objective (Nikon NIR MRD07420 N40X/0.80W) and sent to an IR CCD (IR-1000, DAGE-MIT).
For a first control of ReaChR expression, we performed widefield fluorescence imaging with a system comprising 2 interchangeable LED sources (Thorlabs M470L2, for YFP and M565L3 for dTomato) filtered by 2 interchangeable bandwidth excitation filters (Semrock FF01-452/45 for YFP and F01-545/55-25 for dTomato) and coupled to a diffuser (DG10-1500, Thorlabs) and an achromatic lens (f = 30 mm, #LA1805 Thorlabs). Fluorescence was collected through a tube lens (f = 200 mm), separated from excitation light using a dichroic mirror (Semrock FF510-Di02 for YFP and FF580-FDi01 for dTomato) and detected by a CCD camera (Orca-05G, Hamamatsu) after passing through a visible bandwidth filter (Semrock FF01-609/181 for YFP and FF01-665/150-25 for dTomato).

Surface Tension Measurement of Lipid-Buffer Interface

Check if the same lab product or an alternative is used in the 5 most similar protocols
A custom pendant droplet tensiometer was created to measure the surface tension of the TAG-buffer interface upon the addition of PLs. The droplet volume was controlled by a syringe pump (NanoJet, Chemyx) with a 1 mL TAG-filled syringe (1001 LT SYR, Hamilton) connected via a PEEK tubing to a 30-gauge blunt-tipped needle (930050–90BTE, Metcal) within a polystyrene cuvette (759076D, BrandTech). The droplet was imaged with CMOS camera (MU233-FL, AmScope), tube lens (TTL180-A, ThorLabs), and 4x air objective (PlanN, Olympus) after illumination with a diffused (DG10–1500, Thorlabs) desktop LED lamp (DLST01-S, Newhouse). Images were analyzed and the surface tension was extracted with FIJI and OpenDrop.31 (link),32 (link) FIJI was used to convert the

Near-Infrared Fluorescence Imaging System

Check if the same lab product or an alternative is used in the 5 most similar protocols
A conventional near-infrared planar fluorescence imaging system was built to obtain 2D fluorescence images after each endoscopic imaging experiment for further cross validation. As schematically shown in Figure 3, a CW 785 nm laser (M5-785-0080, Thorlabs, Newton, NJ, USA) was used as the light source. The light beam was split into two parts that were respectively coupled into two fiber bundles, and then traveled through light diffusers (DG10-1500, Thorlabs, Newton, NJ, USA) in order to generate homogeneous illumination on the sample mounted on the sample holder. The induced fluorescence signal was collected by a fast charge-coupled device camera (CoolSNAP EZ, Photometrics, Tucson, AZ, USA) with a high performance fluorescent band-pass filter (NT86-381, Edmund Optics, Barrington, NJ, USA) mounted in the front for filtering out non-fluorescence signals. The laser power used for illumination was the same in all experiments.

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.
