Histological Analysis of Organ Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Organ samples were fixed in fresh 4% paraformaldehyde at 4 °C overnight and further subjected to routine histological procedures for embedding in paraffin. 5-μm sections of the samples from at least three different animals per group were placed on microscopic slides next to one another to enable cross-comparison within a slide after H&E staining or IHC staining with the antibodies indicated. Antibodies used were GFP (D5.1) XP, PTEN (D4.3), phospho (p)-AKT (S473) (D9E), p-ribosomal protein S6 (S235/236) (D57.2.2E), Cleaved Caspase-3 (Asp175) (all: Cell Signaling Technologies, Danvers, MA), Ki67 (VP-K451, Vector Laboratories, Burlingame, CA), and CD3 (A0452) (DAKO, Glostrup, Denmark). Stained slides were scanned with a Pannoramic Scan 250 Flash or MIDI system and images acquired using Pannoramic Viewer 1.15.2 (both: 3DHistech, Budapest, Hungary). Additional images were taken on a Zeiss Axio Imager.Z2 system.

Immunohistochemical Analysis of CD3 Expression in Murine Spleen

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunohistochemistry was performed on the spleen of NOD/SCID mice to investigate changes in CD3 expression. The spleen tissues were incubated in 4% paraformaldehyde for 24 h. Then, the tissues were embedded into paraffin and sliced into 5-μm sections, followed by staining with CD3 antibody (1:500). The sections were placed at 4 °C overnight. The next day, the stained tissues were added with the secondary antibody (1:5000) and incubated for 2 h. After washing with PBS, the samples were scanned using a Pannoramic Scan 250 Flash (3DHISTECH Kft, Budapest, Hungary), and the images were captured using QCapture (QImaging, Burnaby, Canada) with QImaging on a Macintosh computer.

Immunohistochemical Analysis of Liver Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
Liver tissue samples were fixed in 4% paraformaldehyde and embedded in paraffin according to standard procedures. Sections were incubated with the indicated primary antibodies overnight at 4 °C. Thereafter, the slides were incubated with a secondary anti-rabbit or anti-mouse IgG antibody (ZSGB-BIO, Beijing, China) and visualized using 3,3'-diaminobenzidine (ZSGB-BIO). Stained slides were scanned with a Pannoramic Scan 250 Flash or MIDI system, and images were acquired using Pannoramic Viewer 1.15.2 (3DHistech, Budapest, Hungary).

Histopathological Analysis of Liver Fibrosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Liver specimens were fixed in 4% paraformaldehyde, embedded in paraffin and cut into 4 µm sections. Then, the specimens were deparaffinized, hydrated and stained by standard methods. To examine hepatic morphology and assess liver fibrosis, H&E and Sirius Red staining were performed. Sections were immune‐stained for SLC27A5 (1:500, NBP2‐37412, Novus Biologicals, CO, USA), α‐SMA (1:300, 19245T, CST, MA, USA), F4/80 (1:300, 70076T, CST), or RUNX2 (1:300, 20700‐1‐AP, Proteintech, IL, USA) overnight at 4 °C. Sections were then incubated with a secondary anti‐rabbit or anti‐mouse IgG (ZSGB‐BIO, Beijing, China) and stained using 3,3′‐diaminobenzidine (ZSGB‐BIO). Stained slides were scanned with a Pannoramic Scan 250 Flash and images were acquired using Pannoramic Viewer 1.15.2 (3DHistech, Budapest, Hungary). Immunostaining and Sirius Red staining were quantified by threshold analysis using the NIH ImageJ software. The immunohistochemical staining of SLC27A5 and RUNX2 was semi‐quantitatively analyzed using the immunoreactive scoring system.[62 (link)

Liver samples were fixed in fresh 4% paraformaldehyde and subjected to routine histological procedures for embedding in paraffin. Then, the samples were cut in to 4.5-μm sections, which were processed for hematoxylin and eosin (HE) staining or IHC staining with antibodies targeting PCK1(1:500), and β-catenin (1:500). For IHC assay, the sections were incubated with secondary anti-rabbit IgG (ZSGB-BIO, Beijing, China) and stained with 3,3′-diaminobenzidine (ZSGB-BIO). Stained slides were scanned with a Pannoramic Scan 250 Flash or MIDI system and images were acquired using Pannoramic Viewer 1.15.2 (3DHistech, Budapest, Hungary).

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.
