Whole-cell lysates were prepared by washing cells directly in wells with ice-cold PBS, followed by lysis on ice in RIPA buffer (50 mM Tris-HCl/pH 7.5, 1% (wt/vol) Triton X-100, 1% (wt/vol) glycerol, 0.5% sodium deoxycholate, 0.1% sodium dodecylsulphate, 137 mM sodium chloride, 1 mM sodium orthovanadate, and 0.5 mM EDTA) complemented with Complete™ protease inhibitor cocktail. Cell debris was removed by centrifugation (21,000 g, 10 min, 4°C) and the protein concentration of the supernatant was measured with BCA protein assay kit (Uptima, Montluçon, France).
LSR was detected with a rabbit polyclonal anti-LSR antibody (clone X-25) (dilution 1:500; sc-133765; Santa Cruz) and tubulin with a mouse monoclonal anti-tubulin antibody (dilution 1:10000; T9026; Sigma-Aldrich). Horseradish peroxidase-conjugated donkey anti-mouse IgG (H&L) (#610–703–124; Rockland) or goat anti-rabbit IgG (H&L) (#7074; Cell Signaling) antibodies (dilutions 1:3000) were used as secondary antibodies.

Patients’ serum samples were collected before and after treatment and stored at temperatures – 70°C. The same batch of ELISA (Shanghai Jianglai Biotechnology Co., Ltd, Shanghai, China) was used to detect the levels of ICAT and β-catenin proteins in peripheral blood (PB). Before analysis, the serum samples and kit were equilibrated at room temperature (25°C) for 60 minutes (min), and standard wells and sample wells were set. After that, the assay procedure was carried out according to manufacturer’s instructions. Western blotting was used to analyze ICAT protein. The total proteins of AML samples were extracted using serum protein extraction kit (Beyotime Biotechnology Co., Ltd, Beijing, China). Protein concentration was determined by bicinchoninic acid method according to the manufacturer’s protocol (KeyGEN Biotech, China).The PVDF membranes were incubated with the ICAT antibodies (Abcam, England) at 4°C overnight, and membranes were probed with goat anti-rabbit IgG (H + L) (Cell Signaling Tech, USA), then developed by ECL substrate (Pierce, USA).

A total of 1×107 CAR T cells per CAR were stimulated with 3T3-hCD19 target cells for 24 hours or left unstimulated. Cells were lysed with radioimmunoprecipitation assay buffer and total protein was quantified by ND1000 (Nanodrop); 20 µg of lysate was loaded onto the gel. Proteins were detected using anti-phospho-lymphocyte-specific protein tyrosine kinase (pLCK) (1:1000 5% BSA; phospho Tyr505; Cell SignaliNg), anti-lymphocyte-specific protein tyrosine kinase (LCK) (1:2000 5% BSA; BD), and anti-glyceraldehyde 3-phosphate dehydrogenase (1:5000 5% BSA; Cell SignaLing). Goat antirabbit IgG (H+L) and goat antimouse IgG (H+L) (Cell Signaling) were used as secondary antibodies. The secondary antibodies were diluted in 5% BSA at a 1:10 000 dilution. Primary antibodies were incubated at 4°C overnight, and secondary antibodies were incubated at room temperature for 2 hours. ChemiDocMP Imaging System (Bio-Rad) was used to detect enhanced chemiluminescence (Pierce ECL Western Blotting Substrate) western blotting signals.

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.
