Western Blot Analysis of RNF6 Protein

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were treated with RIPA buffer (Beyotime, China) to obtain the total cell proteins, which were quantified using the micro bicinchoninic acid (BCA) method. Proteins (50 μg) were separated by SDS-PAGE, transferred to PVDF membranes, and sealed with 5% skimmed milk at 37°C for 2 h. Then, the membrane was combined with RNF6 (ab204506; Abcam, USA) or GAPDH (ab9484; Abcam) antibodies overnight at 4°C. The secondary antibody was horseradish peroxidase-labeled goat anti-rabbit IgG (ab205718; Abcam). The ECL method was used to detect the signal, the UVI gel imaging system was used to collect the image, and Image J software (Media Cybernetics, USA) was used to analyze the gray value.

Investigating SIX3 Protein Regulation via Co-Immunoprecipitation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The details of these procedures were described previously [37 (link)]. Anti-SIX3 (Santa Cruz Biotechnology, Dallas, TX, USA; sc-81985), anti-FLAG (Abcam, Cambridge, MA, USA; ab205606), anti-HA (Abcam; ab9110), and anti-IgG (Santa Cruz Biotechnology; sc-2027) antibodies were used for co-immunoprecipitation (Co-IP). Immunoprecipitates were washed at least five times and subjected to western blot analysis using anti-TRIM27 (Abcam; ab78393), anti-NEDD4 (Abcam; ab236512), anti-SMURF2 (Abcam; ab94483), anti-RNF6 (Abcam; ab204506), anti-SYVN1 (Abcam; ab170901), anti-MDM2 (Abcam; ab16895), and Anti-SIX3 (Abcam; ab172131) antibodies. For ubiquitination assays, the lysates of A549 cells transfected with siTRIM27-1 or siNC were used for IP with an anti-IgG (Santa Cruz Biotechnology; sc-2027) or Anti-SIX3 antibody (Santa Cruz Biotechnology; sc-81985) and Protein A/G PLUS-Agarose (Novex, Oslo, Norway), which was performed at 4° C overnight. The eluted proteins were then detected by western blot analysis using an anti-ubiquitin (Ub) antibody (Abcam, ab7780).

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.
