TGF-β Signaling Pathway Activation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were serum-starved overnight and treated with 100pM TGF-β for 60 minutes. Cells were lysed in 2× Laemmli sample buffer, and the proteins were resolved on a 10% SDS-PAGE gel. All primary antibodies (Slug #9585, p-Smad2 #3108, Smad2 #3103, p-Smad3 #9520, Smad3 #9523, p-ERK1/2 #9101, ERK1/2 #9102, p-AKT #4058, AKT #4691, p-p38 #4631, p38 #9212) were purchased from Cell Signaling (Danvers, MA, USA) except for β-actin (Sigma, AA5441) and N-cadherin (#610921) and E-cadherin (#610182) (BD Biosciences). Anti-mouse (#5470) and anti-rabbit (#5151) secondary antibodies were purchased from Cell Signaling. Blots were scanned using the LI-COR Odyssey (LI-COR Biosciences, Lincoln, NE, USA).

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.
