Quantitative Analysis of Protein Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total proteins were extracted using radio immunoprecipitation assay buffer containing 1% phenylmethanesulfonyl fluoride and quantified by a BCA Protein Assay Kit (Pierce, Rockford, IL, USA). Equivalent amounts of protein were loaded onto 10% sodium dodecyl sulfate polyacrylamide gel electrophoresis and then transferred into polyvinylidene difluoride membranes. After blocked by skim milk, membranes were incubated in the primary antibodies overnight at 4°C. Primary antibodies were as follows: NDRG3 (1:1,000; Abcam), Src (1:500; Cell Signaling Technology, Boston, MA, USA), p-Src (Try419, 1:1,000; Santa Cruz Biotechnology Inc., Dallas, TX, USA), and GAPDH (1:10,000; Abcam). Membranes were then incubated with horseradish peroxidase-conjugated secondary antibody for 2 hours at room temperature and were visualized by a Tanon detection system with electrochemiluminescence reagent.

For nuclear and cytoplasmic extraction, cells were cultured in an RPMI-1640 medium with 10% FCS for 48 h, and then harvested with trypsin, and washed twice with PBS. Nuclear and cytoplasmic fractions were separated using the NE-PERTM Nuclear and cytoplasmic extraction kit (Thermo, Rockford, NJ, USA) as described by the manufacturer. Equal amounts of whole cell, nuclear, or cytoplasmic lysis were loaded onto a 10% SDS-polyacrylamide gel and assayed by enhanced chemiluminescence as described by the manufacturer (PerkinElmer Inc, Waltham, MA, USA). Blotting membranes were probed with antiserum of MT3 (Sigma-Aldrich Co.), heme oxygenase-1 (HO-1; Stressgen, Victoria, BC, Canada), NDRG1 (Invitrogen), NDRG2, NDRG3 (Abcam, Cambridge, UK), HIF-1α, MASPIN (BD Biosciences, San Jose, CA, USA), HIF-2α (Novus, Littleton, CO, USA), or β-actin antiserum (Millipore, Billerica, MA, USA). The intensities of different bands were analyzed using the GeneTools of ChemiGenius (Syngene, Cambridge, UK).

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.
