5 protocols using mirax midi

1

Quantification of Cell Populations in DG and HC

Slides were scanned by a digital slide scanner (Mirax Midi, 3DHistech Ltd., Budapest, Hungary), equipped with a Panoramic Viewer 1.15.4, a CaseViewer 2.1 program and a QuantCenter, HistoQuant module (3DHistech Ltd., Budapest, Hungary). For quantifications, all sections derived from each animal were analyzed. In DG and HC, the regions of interest (ROI) were manually outlined. Antibody-positive cell types were counted and quantified from ROIs. The number of stem cells (BrdU+) and neuroblasts (DCX+) were assessed by the observers. The densities (%) of neurons (NeuN+), microglia (Iba1+), and astrocytes (GFAP+) were calculated by the quantification software. To assess cell densities, we divided the total number of counted cells per animal with the DG/HC area, and represented them as cells/mm2 (BrdU+, DCX+) or % (NeuN+, Iba+, GFAP+).

Slides were scanned by a digital slide scanner (Mirax Midi, 3DHistech Ltd., Budapest, Hungary), equipped with a Pannoramic Viewer 1.15.4, a CaseViewer 2.1 program, and a QuantCenter, HistoQuant module (3DHistech Ltd., Budapest, Hungary). For quantifications, all sections derived from each animal were analyzed (12 slices per animal). In DG and HC, the regions of interest (ROI) were manually outlined. Antibody-positive cell types for all ROIs were counted and quantified. The number of stem cells (BrdU+) and neuroblasts (DCX+) were assessed at the border between GCL and the hilus. The densities (%) of neurons (NeuN+), microglia (Iba1+), astrocytes (GFAP+) and Aβ plaques were calculated by the quantification software. To assess cell densities, we divided the total number of counted cells per animal with the DG/HC area, and presented the results as cells/mm2 (BrdU+, DCX+) or percentages (NeuN+, Iba1+, GFAP+, Aβ plaques).

Slides were scanned by a digital slide scanner (Mirax Midi, 3DHistech Ltd., Budapest, Hungary), equipped with a Pannoramic Viewer 1.15.4, CaseViewer 2.1 program and a QuantCenter, HistoQuant module (3DHistech Ltd., Budapest, Hungary). For quantification, all of the sections were analyzed. The HC and the CTX were manually outlined as the regions of interest (ROI). Antibody-positive cell types from the ROIs were counted and quantified. The percentile densities of microglia (Iba1+), astrocytes (GFAP+), and Aβ plaques were quantified by the quantification software. The cell density was represented as a percentage.

Immunohistochemical Analysis of CD44 in White Adipose Tissue

Following terminal anesthesia, vWAT were removed, fixed in 4% formalin, and subsequently embedded in paraffin. Immunohistochemical staining was performed on 4 μm tissue sections using a BOND-MAX Immunohistochemical staining machine (Leica). The sections were incubated with rabbit anti-CD44 antibody (Abcam cat.no: ab157107; 1:1000). A labeling system (Bond Polymer Refine Detection, DS9800, Leica) containing horseradish peroxidase (HRP) conjugated goat anti-rabbit secondary antibody and DAB-3 (3′diaminobenzidine) as the chromogen was used to detect the antigen signal. Cell nuclei were counterstained with hematoxylin. The immunostained sections were digitally scanned using a slide scanner (MiraxMidi, 3DHistech Ltd., Budapest, Hungary). Investigators performing immunohistochemical staining and evaluation were unaware of the group allocation.

Immunohistochemical Quantification of Foxp3+ Cells in Heart Allografts

Check if the same lab product or an alternative is used in the 5 most similar protocols
Heart allografts were fixed in 10% v/v neutral buffered formalin, paraffin-embedded, sectioned, and stained with hematoxylin and eosin. Additionally, sections were assessed by standard immunohistochemical staining for forkhead box P3 (Foxp3; eBioscience, Clone FJK-16s). Whole slide images of stained specimens were generated by scanning with a Mirax MIDI (3D Histech, Budapest, Hungary). Digital images were captured using Panoramic Viewer (Version 1.14; 3D Histech). 10× images were captured using an AxioStar Plus microscope (Zeiss) with a digital camera (AxioCam INC, Zeiss). Foxp3+ cells were quantified by counting positive cells within 2–3 fields per heart.

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.
