Immunoblot Analysis of Protein Samples

Proteins were separated using 4–12% gradient polyacrylamide SDS–PAGE gels (Life Technologies) and electrotransferred to 0.2 μM nitrocellulose membranes (GE Healthcare, Velizy-Villacoublay, France). After blocking in Tris-buffered saline with 0.1% Tween and 5% bovine serum albumin, membranes were blotted overnight at 4 °C with the appropriate primary antibodies. Primary antibodies were detected using the appropriate horseradish peroxidase-conjugated secondary antibodies. Immunoreactive bands were visualized by enhanced chemiluminescence (PI32209; Thermo Fisher Scientific, Bremen, Germany) with a Syngene camera. Densitometric analyses of immunoblots were performed using the GeneTools software.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Proteins were separated using 4–12% gradient poly-acrylamide SDS-PAGE gels (Life Technologies) and electrotransferred to 0.2 µm nitrocellulose membranes (GE Healthcare, Chicago, IL, USA). After blocking with Tris-Buffered Saline with 0.1% Tween and 3% bovine serum albumin, membranes were incubated overnight at 4 °C under continuous shaking with the appropriate primary antibodies. Primary antibodies were detected using the appropriate secondary antibodies coupled with horseradish peroxidase. Immunoreactive bands were visualized by enhanced chemiluminescence with a Syngene camera. Densitometric analyses of immunoblots were performed using the GeneTools software.

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.
