The frozen slice was blocked by 10% goat serum (Sigma, USA) for 1 h at room temperature, then incubated with the primary antibody of anti-GFAP (chicken, Millipore, USA; rabbit, Dako, Japan), anti-VIM (chicken, Abcam, USA), anti-SerpinA3N (goat, R&D Systems), anti-Iba1 (rabbit, FUJIFILM Wako Pure Chemical Corporation, USA), anti-MBP (rabbit, Cell Signaling Technology, USA) at 4 °C overnight, washed three times, then incubated with the fluorescence-labeled second antibody (Invitrogen, USA) 1 h at room temperature; washed three times, and mounted with DAPI. Images were captured with a confocal laser-scanning microscope (Zeiss LSM710, USA) or Fluorescence Microscope BZ-X800 (KEYENCE, Japan).

Cells (1 × 104/well) were seeded on 8-well chamber slides (Lab-Tech) after transfection. The cells were fixed, permeated and blocked. Then, they were incubated with the following antibodies: anti-VIM (1:200, Abcam), anti-ITGAV (1:1000, Cell Signaling Technology), anti-ITGB1 (1:1000, Cell Signaling Technology), anti-ITGB3 (1:500, Cell Signaling Technology) or anti-CD47 (1:200, Abcam). The secondary antibody, Alexa Fluor 488-conjugated goat anti-mouse IgG or anti-rabbit IgG (1:500, Invitrogen), was applied for 1 hour. Slides were mounted with antifading solution containing 4′-6′-diamidino-2-phenyl-indole (Vector Laboratories). Images were taken using a confocal microscope (Zeiss). All experiments were conducted in triplicate.

Cells were collected and washed with PBS, and protein was extracted using lysis buffer (PMSF: RIPA=1:100, Beyotime Institute of Biotechnology, Haimen, China). Protein concentrations were measured by BCA Protein Assay Reagent (Pierce; Thermo Fisher Scientific, Inc.). Total proteins were separated by 10% SDS-polyacrylamide gel electrophoresis, electro-transferred onto polyvinylidene fluoride membranes (EMD Millipore, Billerica, MA, USA), and blocked with 5% non-fat milk in PBS with 0.05% Tween-20 for 2 h. The membranes were incubated overnight at 4°C with the following antibodies: Anti-STMN1 (cat. no. ab52630; dilution 1:500; Abcam), anti-E-Cad (cat. no. ab40772; dilution 1:500; Abcam), anti-VIM (cat. no. ab92547; dilution 1:500; Abcam), and anti-β-actin (cat. no. ab8227; dilution 1:2,000; Abcam). The membrane was incubated with secondary antibodies for 1 h at room temperature. The immunocomplexes were visualized by enhanced chemiluminescence.

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.
