Axio observer z1 confocal microscope

Manufactured by Yokogawa

The Axio-Observer Z1 is a confocal microscope developed by Yokogawa. It is designed for high-resolution imaging of samples. The microscope utilizes a laser-scanning system to capture detailed images by focusing the laser beam on a specific point within the sample.

50,000 GFP-tagged HS-cells and ΔHS-cells were collected; then seeded for 2 hours over a glass chamber slide (Thermo Fisher Scientific) pre-coated overnight with 1 μg ALCAM then fixed and permeabilized with Fixperm solution quenched with ammonium chloride, then incubated in blocking solution (PBS containing 0.01% Triton X-100 with 1% BSA). Finally, cells were immunolabeled with anti-phospho-SLP-76(pTyr128) followed by anti-mouse Alexa 647. Clustering images of SLP76 at the HS/ALCAM interface were captured using a Zeiss Axio-Observer Z1 confocal microscope equipped with a Yokogawa CSU10 spinning disc, a Zeiss 63x/1.43 NA objective, and a Hamamatsu Orca-AG camera. Single 0.1μm z-slices with SLP-76 puncta at the eGFP.G-expressing T-cell surface were detected and compared to ΔHS-cells.

Imaging the Endothelial-T Cell Interface

The endothelium/HS-T-cells interface was imaged using confocal microscopy. HS-cells and NT T-cells were seeded over HBMEC monolayer, pre-stimulated with TGFβ (0.1 μg/ml) for 4 hours to ensure ALCAM expression, and incubated for 2 hours at 37°C to allow conjugate interactions. Conjugates between HS-cells and HBMEC were then fixed and permeabilized with 4% paraformaldehyde and 0.02 % saponin (Tween), blocked with PBS containing 0.01% Triton X-100 with 1% BSA and stained for LFA-1 open conformation, ICAM1, and Talin-1. Primary antibodies were subsequently detected by anti-mouse AF 647, AF 488 secondary antibodies and anti-rabbit Alexa fluor pacific blue respectively. An extra blocking step was performed between the two anti-mouse human antibodies staining to eliminate background staining. HS-cells/HBMEC conjugates were imaged as 0.2 μm Z-steps to cover the entire volume of the podosynapse, determined individually for each conjugate using a Zeiss Axio-Observer Z1 confocal microscope equipped with a Yokogawa CSU10 spinning disc, a Zeiss 63x/1.43 NA objective, and a Hamamatsu Orca-AG camera. Images were analyzed with Volocity software (PerkinElmer, Waltham, MA). Cluster density of LFA-1, Talin-1, ICAM1 and Actin at the interface were calculated using the formula (volume×MFI) for an equal number of 1×1×1-μm voxels selected to cover the interface.

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.
