Uv 510 confocal microscope

Manufactured by Zeiss

The Zeiss UV 510 confocal microscope is a laboratory instrument designed for high-resolution imaging of biological samples. It utilizes ultraviolet (UV) excitation wavelengths to enable visualization and analysis of cellular structures and components. The core function of the UV 510 is to provide researchers with a versatile platform for advanced fluorescence microscopy studies.

5 protocols using uv 510 confocal microscope

1

Visualization and Quantification of Gene Silencing

Check if the same lab product or an alternative is used in the 5 most similar protocols
For silencing experiments, cells were visualized using a UV 510 confocal microscope (Carl Zeiss, Oberkochen) and a Plan-Neofluar 40×/1.3 oil lens. To image GFP fluorescence, a 488 nm laser beam was used for excitation, and detection was acquired using a BP filter 505–550 nm. Flow cytometry was performed on a BD Accuri C6 flow cytometer; CellQuest or the CFlow Sampler software was used to obtain the gMFI. To determine statistical significance, treatments were compared to cells-only using a one-way analysis of variance (ANOVA), followed by a Dunnett’s multiple comparisons test performed in GraphPad Prism version 9.0.0 for Windows, GraphPad Software, San Diego, California, USA, www.graphpad.com. Data are expressed as the mean ± SEM for n = 20,000 events per treatment. A P-value of <0.05 was considered statistically significant.

For neutrophil mitochondrial images, isolated neutrophils were incubated in complete sea horse media (2 mM glutamine and 25 mM glucose) for 20 min at 37 °C with mitotracker CMX ROS (100 nM). Cells were washed in PBS and incubated with Hoechst (2 μg/ml) for 20 min with 5 °C after which cells were washed in PBS. Neutrophils were placed in a cytospin cartridge and spun at 800 rpm and spun for 3 min. Cells were then fixed in 4% PFA for 20 min, washed and a coverslip was added. A Zeiss UV-510 confocal microscope and 63× oil immersion objective lens was used to capture images using differential interference contrast, 405 and 561 laser paths (pinhole size = 1 airy unit).
Tumour sections were processed fresh-frozen sections and were washed with PBS, mild-fixed with acetone at 4 C, permeablised with 0.05% Triton in PBS and blocked with 5% BSA in PBS. Sections incubated at room temperature for 1 h with the following antibodies (1:100, all from Biolegend): FITC anti-mouse CD3, PerCP/Cy5.5 anti-mouse GR-1, APC anti-mouse c-Kit and counterstained with DAPI. Images were analysed using Fiji (ImageJ).

Experiments were performed using a UV 510 confocal microscope (Carl Zeiss, Oberkochen) and a Plan-Apochromat 63×/1.4 oil lens. To image QD545, a 488 nm laser beam was used for excitation and a BP filter 505–550 nm for detection. To image QD605, a 561 nm laser beam was used for excitation and a BP filter 575–615 nm for detection. All images were taken with a pinhole adjusted to 1 Airy unit. Flow cytometry was performed on a BD Accuri C6 flow cytometer; CellQuest or the CFlow Sampler software was used to obtain the gMFI. Data are expressed as the mean ± SEM for n = 20,000 events per treatment.

Visualizing Silencing and Uptake of Nanoconstructs

Check if the same lab product or an alternative is used in the 5 most similar protocols
The silencing experiments were visualized using a UV 510 confocal microscope (Carl Zeiss, Oberkochen) and a Plan-Neofluar 40×/1.3 oil lens. MDA-MB-231 eGFP cells were plated in glass bottom dishes (Ibidi, Madison), transfected as described above. 3 days upon transfection, the cells were washed three times with PBS and fixed with 4% paraformaldehyde for 20 min at RT for imaging. For GFP imaging, the 488 nm line of an argon laser was used as excitation, and emission was collected using a BP 505–550 filter. The uptake experiments were visualized using a LSM 710 confocal microscope (Carl Zeiss, Oberkochen) and a Plan-Apochromat 63×/1.40 oil lens. MDA-MB-231 cells were transfected with Alexa 456 fluorescently labeled nanoconstructs. The next day, cells were washed three times with PBS and fixed with 4% paraformaldehyde for 20 min at RT for imaging. For Alexa 546 imaging, a DPSS 561 laser was used for excitation, and emission was collected between 566 and 680 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.
