Quantifying Urinary AQP1 Levels

Check if the same lab product or an alternative is used in the 5 most similar protocols
The precipitated proteins were mixed with β-mercaptoethanol, incubated in a boiling water bath for five minutes, and loaded onto precast Any-kD Tris-glycine gels (Bio-Rad Laboratories Inc., Hercules, CA, USA) for electrophoresis so that each well contained 60 μg of creatinine per sample. Normalization to creatinine with urine stored in these conditions is the standard for urinary protein processing via western blotting [16 (link)]. Proteins were transferred onto PVDF membranes and blocked with 5% nonfat milk in PBS-Tween 20. Blocked membranes were incubated overnight with anti-AQP1 (H-55) (Santa Cruz Biotechnology Inc., Santa Cruz, CA, USA), diluted 1 : 500 in blocking buffer. After washing, the membranes were incubated with a 1 : 2000 dilution of goat anti-rabbit IgG HRP-conjugated antibody (Cell Signaling Technology, Danvers, MA, USA) for two hours at room temperature and visualized by chemiluminescence. AQP1 levels were semiquantified in arbitrary units using ImageJ software for area under the curve (AUC) analysis.

Cells were induced for A3A expression using 2 μg/mL Dox for 24 hours. Uninduced cells as well as non-inducible cell lines such as HeLa EGFP were analyzed in parallel. Whole cell extracts were prepared by incubating cells with lysis buffer (RIPA with 1x Halt protease inhibitor cocktail) for 30 minutes at 4°C followed by sonication and centrifugation at 13,000×g for 5 minutes to clarify the lysate. The total protein lysate concentration was measured using Bio-Rad protein assay dye reagent concentrate (Bio-Rad). Protein lysates (20 mg) were separated on 15% SDS-PAGE gel then transferred to a PVDF membrane. The membrane was blocked with 5% (w/v) nonfat milk then probed with mouse anti-β-actin antibody (Cell signaling; 1:1000 dilution), mouse anti-β-tubulin antibody (Cell signaling; 1:1000 dilution), mouse anti-GFP antibody (Santa Cruz; 1:500), and rabbit anti-APOBEC3A/B monoclonal antibody (obtained from Dr. Reuben Harris, University of Minnesota; 1:1000), followed by goat anti-mouse IgG HRP-conjugated antibody (Cell signaling; 1:1000), and goat anti-rabbit IgG HRP-conjugated antibody (Cell signaling; 1:1000). β-actin and β-tubulin served as the loading controls.

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.
