Immunohistochemical Analysis of Immune Cells in HCC

Check if the same lab product or an alternative is used in the 5 most similar protocols
Paraffin-embedded and formalin-fixed HCC samples were cut into 5-μm sections, which were then processed for immunohistochemistry as previously described. Briefly, the sections were incubated with Abs against the following human antigens: CD8 (rabbit monoclonal, clone EP334, ZSBio, China), CD11b (rabbit monoclonal, clone EPR1344, Abcam, UK), CD68 (mouse monoclonal; clone PG-M1; Dako Cytomation, USA), CD15 (mouse monoclonal; clone LeuM1; ZSBio), CD206 (mouse monoclonal, clone 685645, R&D Systems, USA), CD204 (mouse monoclonal, clone SRA-C6, Transgenic, Japan), CD163 (mouse monoclonal, clone 10D6, ZSBio) and CD169 (sheep polyclonal, clone NS0, R&D Systems). Then, the sections were stained in an EnVision System (Dako Cytomation, USA). Positive cells were detected by microscopy and quantified using the Vectra-Inform image analysis system (Perkin-Elmer Applied Biosystems, Foster City, CA, USA).

During the operation, the surgeon performed paraspinal muscle biopsy of the multi dus muscle at the apex vertebra region. The biopsy tissue was wrapped in a semi-humid saline gauze and immediately transferred to the laboratory, where it was drained with blotting paper and was consecutively embedded in tragacanth and OCT compound (Tissue-Tek) and nally frozen in isopentane pre-cooled in liquid nitrogen. Cryostat sections were obtained with 7 to 10 µm thickening. Conventional H&E staining, histochemical staining (NADH-TR, Gomori trichrome, PAS, oil red O), and EnVision two-step immunohistochemical staining were performed under standard techniques that used the following primary antibodies: Dystrophin-1 (Anti-dystrophin rod domain, Leica Biosystems, USA), Dystrophin-2 (Anti-dystrophin C-terminal, Leica Biosystems, USA), Dystrophin-3 (Anti-dystrophin N-terminal, Leica Biosystems, USA), Myosin (Zsbio, China), MHC-1 (Zsbio, China), CD4 (Zsbio, China), CD8 (Zsbio, China), CD20 (Zsbio, China), and CD6 (Zsbio, China)8 or CD163 (Zsbio, China) antibodies respectively (10) .

Surgically resected PitNET specimens and NPs were xed in 4% paraformaldehyde for 24h and then embedded in para n. Para n blocks were cut into 4 µm sections and used for hematoxylin and eosin (HE) or immunohistochemistry (IHC) staining. Protein marker expression of immune cell in ltration, expression of immune checkpoint molecules, and PIT1 transcription factor were detected by SP Rabbit&Mouse HRP DAB Kit (catalog no. CW2069S, CWBIO). Slides were incubated with the following primary antibody: CD68 (catalog no.IR61361-2CN, DAKO), CD163 (catalog no.ZM-0428, ZSGB-BIO), CD4 (catalog no. RMA0620, MXBiotechnologies), CD8 (catalog no. ab4055, Abcam), PD-L1 (catalog no. ab205921, Abcam), PD-1 (catalog no. ZM-0381, ZSGB-BIO), CTLA4 (catalog no. ab237712, Abcam), PIT1 (catalog no.ZM0208, ZSGB-BIO), TPIT (catalog no.ZM-0316, ZSGB-BIO), SF1 (catalog no.ZM-0089, ZSGB-BIO). The estimation of PD-L1 expression followed the guideline of Consensus on the Immunohistochemical Tests in Solid Tumors (2021 version). Stained slides were digitally scanned using Slides Scanning Image System (TEKSQRAY). Images were analyzed using Image J software and quanti cation of positive expression was measured by two independent investigators (Mei Luo and Rui Tang). Cases with staining artifacts or poor tissue integrity following IHC processing were excluded.

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.
