Cells were harvested and lysed in SDS sample buffer (62.5 mM Tris-HCl (pH 6.8), 3% sodium dodecyl sulfate (SDS), 10% glycerol, 50 mM DL-dithiothreitol (DTT), and 0.1% bromophenol blue) with protease inhibitors (Roche, Indianapolis, IN, USA). The protein concentrations were determined by the BCA method (Pierce, Thermo Fisher Scientific Inc., Rockford, IL, USA). The proteins (10 ug) were separated by SDS-PAGE and transferred to a polyvinylidene difluoride membrane. Bovine serum albumin (5%) in TBS-T (1 mol/L Tris-HCl (pH 7.5), 0.8% NaCl and 0.1%Tween 20) was used to block the membrane. Then, the membrane was incubated with anti-ISG15 (Abcam, ab131119, Cambridge, MA, USA), anti-α-tubulin (Abcam, ab126165, Cambridge, MA, USA), and anti-β-actin (Sigma-Aldrich, A5441, St.Louis, USA) antibodies at 4°C overnight. The blots were then treated with an HRP-conjugated secondary antibody (Pierce, Rockford, IL, USA).

Tissue protein lysis was prepared as described (Wang et al, 2009 (link)). Cell lysates were generated with RIPA lysis buffer (Guangzhou Fans Biotechnology, Co. Ltd., Guangzhou, China). Nuclear protein was extracted by using NE-PER Nuclear and Cytoplasmic Extraction Reagents (Thermo Scientific, Rockford, IL, USA). Protein concentration was determined by a standard BCA assay, and 60 μg total cell lysates or nuclear extracts were separated by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS–PAGE). Proteins were transferred onto PVDF membranes (Amersham Biosciences, Buckinghamshire, UK), and membranes were probed with anti-Snail1 (sc-28199; Santa Cruz Biotechnology), anti-MMP2 (#13132), anti-MMP9 (#3852; Cell Signaling), anti-COUP-TFII (PP-H7147-00; Perseus Proteomics, Tokyo, Japan), all in 1 : 1000 dilution, or anti-tubulin (ab126165; Abcam, Cambridge, MA, USA) (1 : 2000 dilution) and visualised with horseradish peroxidase-conjugated secondary antibody (Santa Cruz Biotechnology) and ECL kits (Amersham Pharmacia Biotech, Buckinghamshire, UK). Protein bands were quantified by Total lab software (Nonlinear Dynamics, Newcastle upon Tyne, UK).

Total proteins of cells were separated by 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and transferred to polyvinylidene difluoride membranes. After being blocked with 5% non-fat dry milk in PBS, the membrane was incubated with antibodies to FAPα (1:1,000, AF3715; R&D Systems, Inc., Minneapolis, MN, USA), dipeptidyl peptidase 4 (DPP4; 1:1,000, ab28340; Abcam, Cambridge, MA, USA) or matrix metalloproteinase (MMP)2 (1:1,000, ab86607; Abcam) at 4°C overnight. After being washed several times, the polyvinylidene difluoride membrane was incubated with horseradish peroxidase (HRP)-conjugated secondary antibody at room temperature for 2 hours. The bands were then detected by Pierce ECL Plus Western Blotting Substrate (Thermo Fisher Scientific) according to the manufacturer’s protocols. β-Tubulin protein levels were also determined by using the specific antibody (1:3,000, ab126165; Abcam) as a loading control.

Nasopharyngeal carcinoma cells were harvested and lysed in sodium dodecylsulfate (SDS) sample buffer. Cellular proteins were separated by SDS-PAGE and transferred to polyvinylidene difluoride membranes. Then, the membranes were incubated with MIF (1:1000, Abcam, ab65869) and α-tubulin (1:3000, Abcam, ab126165) antibodies at 4 °C overnight. At last, the blots were treated with a horseradish peroxidase (HRP)-conjugated secondary antibody.

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.
