Western Blot Analysis of NOTCH1

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were washed 3 times in cold PBS and lysed in RIPA buffer. The proteins were separated on 10% SDS-PAGE gels and then blotted onto PVDF membranes. The membrane was blocked with 5% milk and incubated with anti-NOTCH1 antibody (Abcam, UK) overnight and then incubated with HRP-conjugated secondary antibody (Abcam, UK) for 2 h. The proteins were detected using an ECL reagent kit (Thermo Fisher Scientific, USA).

Western Blot Analysis of EMT Markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Whole-cell lysates were collected using RIPA buffer. Proteins were separated using 10% SDS polyacrylamide gel, and the gels were transported to PVDF membranes (Thermo Fisher Scientific, CA, USA). The PVDF membranes were incubated with 5% skim milk in TBST at room temperature for 1 h. Later on, the PVDF membranes were probed with primary antibodies: anti-DCLK1 antibody (1:1000, Abcam, CA, USA), anti-Notch1 antibody (1:3000, Abcam, CA, USA), anti-E-cadherin (1:3000, Abcam, CA, USA), anti-Vimentin (1:3000, Abcam, CA, USA), anti-slug (1:1000, Abcam, CA, USA), anti-TGF-β (1:1000, Abcam, CA, USA), anti-MMP2 (1:1000, Abcam, CA, USA), anti-MMP9 (1:1000, Abcam, CA, USA) and anti-GAPDH antibody (1:3000, Bioworld, CA, USA) overnight at 4 °C. After that, the PVDF membrane was incubated for 1 h in secondary antibody anti-rabbit IgG second antibody (Abcam; ab150077) (1:5000) at room temperature for 1 h. Finally, the immunoreactivity was detected using ECL reagent (Santa Cruz Biotechnology).

All the primary antibodies were diluted to 1:1,000. The secondary antibodies used in the present study were as follows: HRP-labeled goat anti-rabbit IgG (cat. no. 97051; Abcam) and HRP-labeled goat anti-mouse IgG (cat. no. 205719; Abcam). The secondary antibodies were diluted to 1:5,000.

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.
