Phosphor jnk p jnk

Manufactured by Cell Signaling Technology
Sourced in United States

Phosphor-JNK (p-JNK) is an antibody that specifically recognizes the phosphorylated form of c-Jun N-terminal kinase (JNK). JNK is a member of the mitogen-activated protein kinase (MAPK) family and plays a role in cellular stress response and apoptosis. The Phosphor-JNK antibody can be used to detect the activation state of JNK in biological samples.

Total protein of macrophages was extracted using radio-immunoprecipitation assay lysis buffer according to the manufacturer's instruction (Beyotime, Shanghai, China). Proteins were separated by 10% SDS-PAGE, transferred onto polyvinylidene difluoride membranes, and incubated overnight with primary antibodies at 4°C. Rabbit polyclonal antibodies against phosphor-P38 (p-P38) (#4511T), P38 (t-P38) (#8690T), phosphor-JNK (p-JNK) (#9255S), phosphor-ERK (p-ERK) (#4370T), ERK (t-ERK) (#4695T), and glyceraldehyde-phosphate dehydrogenase (#5174T) were purchased from Cell Signaling Technology. Mouse polyclonal antibody against JNK (t-JNK) (#9252T) was also purchased from Cell Signaling Technology. Secondary antibodies were added and co-incubated for 2 h at room temperature. Protein bands were visualized using ECL detection reagent. The protein expression was quantified by densitometry and normalized to glyceraldehyde-phosphate dehydrogenase.

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.
