Western Blot Analysis of siRNA Knockdown

Check if the same lab product or an alternative is used in the 5 most similar protocols
48 h after transfection with siRNA, HT1080s were lysed in RIPA buffer (1% Triton X-100, 0.5% sodium deoxycholate, 0.1% sodium dodecylsulfate, 150 mM NaCl, and 50 mM Tris, pH 8) plus 1× protease inhibitors without EDTA (Roche). Cleared lysates were combined with an equal volume of 2× sample buffer, heated to 95°C for 5 min, resolved by SDS-PAGE on a 4–12% Tris-glycine polyacrylamide gel (Thermo Fisher Scientific), and transferred to nitrocellulose (0.2-µm pores; Thermo Fisher Scientific). Secondary antibodies used for Western blotting were: goat anti–rabbit IgG Alexa 680 and goat anti–mouse IgG Alexa 680 (Thermo Fisher Scientific). Blots were visualized on an Odyssey Scanner (LI-COR Biosciences). Western blots were quantified by normalizing the signal intensity of nesprin 3, vimentin, or lamin A to the corresponding GAPDH signal and determining the change in expression of the siRNA-mediated protein knockdown relative to the control.

Western Blot Analysis of E-cadherin and Vimentin

Check if the same lab product or an alternative is used in the 5 most similar protocols
After treatment, MDCKs were lysed using RIPA buffer (1% Triton X-100, 0.5% sodium deoxycholate, 0.1% SDS, 150 mM NaCl, and 50mM Tris, pH8) supplemented with 1X protease inhibitors without EDTA (Roche). Cleared lysates collected were combined with an equal volume of 2X reducing sample buffer, heated to 95°C for 5 min, resolved on 4–12% Tris-glycine polyacrylamide gel (Thermo Fisher Scientific), and then transferred to nitrocellulose membranes containing 0.45 μm pores (Thomas Scientific). Secondary antibodies: goat anti-rabbit IgG Alexa 680 and goat anti-mouse IgG Alexa 680 (Thermo Fisher Scientific). Blots were scanned using Odyssey Scanner (LI-COR Biosciences). Western blots were quantified by normalizing the signal intensity of the E-cadherin or vimentin bands to the corresponding GAPDH signal following background subtraction.

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.
