Visualizing Cells with SHG and Autofluorescence

The cells were seeded on microscopic glass coverslips in a 24-well plate, were cultivated for 3 weeks, and were visualized using a 63× water immersion objective (HC PL APO CS 2 63×/1.20 Water), mounted on a Leica DMi8 inverted microscope with a Leica TCS SP8 X confocal unit (Leica Microsystems, Weltzar, Germany). A Chameleon Discovery TPC pulsed femtosecond laser (Coherent Inc., USA; 860 nm tunable output, 80 Mhz, 1.6 W) was used to generate SHG and autofluorescence signals. Leica non-descanned HyD detectors and a 430/24 band-pass filter were used for collecting SHG signals, and Leica non-descanned HyD detectors and a 610/75 band-pass filter were used for collecting autofluorescence signals.

Visualizing Meningeal Lymphatic Vessels

Check if the same lab product or an alternative is used in the 5 most similar protocols
Adult Prox1GFP, LckCre::tdTOMATOfl/fl mice were anesthetized by ketamine/xylazine intraperitoneal (i.p.) injection. Mice were injected intravenously (i.v.) or into the cisterna magna (i.c.m.) with Qtracker655 vascular tracker (ThermoFisher - Qdot655 – 5µl with 95µl saline (i.v.) or 5µl (i.c.m.)). Furamidine dihydrochloride (125µg -Sigma Aldrich) was injected i.v. prior to imaging. Meningeal lymphatic vessels were imaged through a thinned skull preparation above the superior sagittal, transverse sinuses or cerebellum. The core temperature of the mice was maintained at 37C. Imaging was performed with a Leica TCS SP8 multiphoton system (Leica Microsystems) equipped with a Chameleon Ultra II tunable Ti:sapphire laser (Coherent). GFP, tdTOMATO and Qdot655 were excited with an excitation wavelength of 880 nm (or 780nm for furamidine57 (link)). Second harmonic signal (bone and meningeal signal) was visualized using a 400/450 external detector. Images were obtained using a 25X water immersion objective with 0/95NA and external HyD non-descanned detectors (Leica Microsystems). Three-dimensional images data were collected by obtaining images from the x,y and z-planes. The resulting images were analyzed with Imaris software (Bitplane).

Visualizing Meningeal Lymphatic Vessels

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mice were anaesthetized by ketamine/xylazine injection i.p. and injected i.c.v. (into the cisterna magna) with 5μl of QDot655 (Invitrogen) or 5μl of Alexa488-conjugated anti-Lyve-1 antibody (ALY7, eBioscience). Mice were co-injected i.v. with 25μl of 10% fluorescein sodium salt (Sigma-Aldrich) or 5μl of QDot655 (Invitrogen). Meningeal lymphatic vessels were imaged through a thinned skull preparation. The core temperature of the mice was monitored and maintained at 37°C. Imaging was performed with a Leica TCS SP8 multiphoton microscopy system (Leica Microsystems) equipped with a Chameleon Ultra II tunable Ti:sapphire laser (Coherent). GFP and QDot655 were excited with an excitation wavelength of 880 nm. Images were obtained using a 25× water immersion objective with 0.95 NA and external HyD non-descanned detectors (Leica Microsystems). Four-dimensional imaging data were collected by obtaining images from the x, y, and z-planes over time. The resulting images were analyzed with Imaris software (Bitplane).

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.
