Colon Tissue Microarray Analysis of Cyclin D1 and CD163

Check if the same lab product or an alternative is used in the 5 most similar protocols
Tissue microarrays for normal and cancerous human colon tissues (sample ID: BC05118d) were purchased from Biomax (Rockville, MD). The tissue microarray samples were dried for 20 minutes at 60 °C, deparaffinized with xylene, and rehydrated. Antigens were retrieved by heating the sections at 95 °C in 0.01 M sodium citrate buffer, pH 6.0. Endogenous peroxidase activity was blocked using 3% hydrogen peroxide. The samples were stained with antibodies against cyclin D1 (1:100, MA5-16356; Thermo Fisher Scientific) and CD163 (1:100, MA5-11458; Thermo Fisher Scientific). Incubation with a biotin-conjugated secondary antibody and visualization were performed using the VECTASTAIN Elite ABC-HRP kit (Vector Laboratories, Burlingame, CA), followed by counterstaining with hematoxylin. The processed slides were analyzed under a light microscope (IX53; Olympus, Tokyo, Japan) using the CellSens Dimension program. Cyclin D1 immunostaining intensity in macrophage-enriched areas of colon tissues was analyzed using ImageJ software (National Institutes of Health, Rockville, MD).

Immunohistochemistry and immunofluorescence staining of organoids were performed as described previously [21 (link)]. The following primary antibodies were used: rabbit anti-MUC2 (1:200; sc15334, Santa Cruz Biotechnology, Dallas, TX), rabbit anti-TFF3 (5 μg/ml; ab101099, Abcam, Cambridge, MA), rabbit anti-Ki67 (1:150; RM-9106, Thermo Fisher, Carlsbad, CA), rabbit anti-β-catenin (1:200; #9582, Cell Signaling Technology), mouse anti-C-myc (1:200; sc40, Santa Cruz Biotechnology), and rabbit anti-cyclin D1 (1:150; MA5–16356, Thermo Fisher Scientific).
For immunofluorescence staining, primary antibodies were rabbit anti-cleaved caspase-3 (1:400; #9661, Cell Signaling Technology), rabbit anti-laminin 332 (1:500; kind gift from Peter Marinkovich, Stanford University, Stanford, CA), and goat anti-collagen IV (1:100; AB769, Millipore). Secondary antibodies were AlexaFluor 568 goat anti-rabbit IgG (1:500; A-11036, Invitrogen), AlexaFluor 488 donkey anti-goat IgG (1:500; A-11055, Invitrogen), and AlexaFluor 488 goat anti-rabbit IgG (1:500; A-11034, Invitrogen). Nuclei were counterstained with Hoechst 33342 (Thermo-Fisher Scientific).

Western Blot Analysis of Cell Signaling Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cells were lysed in a radioimmunoprecipitation assay buffer containing protease inhibitor cocktail (Roche, Mannheim, Germany). Pierce Coomassie Protein Assay (Bradford, Thermo Fisher Scientific, Waltham, MA, USA) was applied to measure the concentrations of protein extracts. Aliquots of protein extracts (40 µg/lane) were subjected to sodium dodecyl sulfate–polyacrylamide gel electrophoresis and transferred to phosphatidylcholine membranes (Sartorius, Göttingen, Germany). The membranes were blocked using skim milk and separately incubated overnight at 4 °C with primary antibodies against RFP (1:1000, MA5-15257, Thermo Fisher Scientific), Cre (1:1000, ab188568, Abcam), CDK4 (1:1000, MA5-12984, Thermo Fisher Scientific), cyclin D1 (1:200, MA5-16356, Thermo Fisher Scientific), cyclin A2 (1:500, 18202-1-AP, Proteintech), cyclin B1 (1:500, 55004-1-AP, Proteintech), and β-actin (1:5000, MA5-15739, Thermo Fisher Scientific). Subsequently, the membranes were probed using HRP-conjugated rabbit/mouse anti-IgG for 1 h at room temperature. Finally, protein bands were detected through enhanced chemiluminescence (ECL; PerkinElmer Life Science, Hopkinton, MA, USA) using a UVP Biospectrum (UVP, LLC Upland, CA, USA).

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.
