Immunoblot Analysis of Protein Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were lysed in M-PER Mammalian Protein Extraction Reagent (Thermo Fisher Scientific) containing protease inhibitor cocktail (Roche). Immunoblot analysis was conducted with 25–30 μg of total cell protein. The protein concentration of cell lysates was determined with the Bradford reagent (Bio-Rad). Equal amounts of total protein were subjected to SDS-PAGE on a 6% or 8% gel, and then transferred to nitrocellulose membranes (Bio-Rad). The membranes were blocked in 5% milk, and then incubated in PBST buffer with primary antibodies at 4°C overnight, followed by incubation with horseradish peroxidase-conjugated secondary antibody (1:5000, Thermo Fisher Scientific) for one hour at room temperature. Membranes were exposed to HyBlot CL film at room temperature. Primary antibodies used were anti-DHHC5 (HPA014670, Sigma-Aldrich), anti-GAPDH (GT239, GeneTex), anti-HSP90 (SC-13119, Santa Cruz Biotechnology).

LuCaP xenografts were manually homogenized in RIPA buffer containing 2M Urea and protease inhibitors (Fisher Scientific). The homogenates were sonicated and centrifuged to remove insoluble material. Ten-micrograms of total protein lysate was electrophoresed on 4–12% Bis-Tris gels (Invitrogen) with MES buffer. The gels were transferred to nitrocellulose and blocked with 5% BSA in PBS/0.1% Tween-20 and subsequently probed with 1:1000 dilution of anti-SRRM4 antibody (HPA052783; Atlas Antibodies AB) or 1:2000 dilution of anti-GAPDH (GT239; Genetex). Protein was visualized using Supersignal West Femto Chemiluminescent Substrate (Thermo Scientific).

To verify the induction of autophagy, a Western blot analysis was conducted using 40 µg of the total protein extracted from the breast cancer (BC) cells. The cells were lysed using Cell Lysis Buffer II (Thermo-Fisher Scientific, Waltham, MA, USA), following treatment with DDC for 24 and 48 h as well as with the positive control resveratrol (Rv). The proteins were separated on 7.5 or 12% SDS-PAGE gels and subsequently transferred onto polyvinylidene fluoride (PVDF) membranes (both from Thermo-Fisher Scientific, Waltham, MA, USA). The membranes were blocked for 1 h using 5.0% (w/v) BSA in TTBS and then incubated overnight at 4 °C with primary antibodies: anti-mTOR-Ser2448 (Proteintech, Rosemont, Illinois, USA), anti-Beclin-1 (D40C5) (Cell Signaling Technology, Denver, MA, USA), anti-p62, and anti-LC3-II (GeneTex, Irvine, CA, USA). Anti-GAPDH (GT239) (GeneTex, Irvine, CA, USA) was employed as the loading control.
Following primary antibody incubation, the membranes were incubated for 2 h at room temperature with either anti-mouse IgG or anti-rabbit IgG secondary antibodies (1:5000) (Merck Group, Darmstadt, Germany) [28 (link)]. Bands were visualized using the 1-Step™ TMB-Blotting Substrate Solution (Thermo-Fisher Scientific, Waltham, MA, USA), which generates a blue precipitate. Band density was normalized and semi-quantified using the ImageJ V 1.8.0 software.

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.
