Rabbit anti phospho erk1 2 t202 y204

Manufactured by Cell Signaling Technology

Rabbit anti-phospho-ERK1/2 (T202/Y204) is a primary antibody that recognizes the phosphorylated forms of extracellular signal-regulated kinase 1 and 2 (ERK1/2) at threonine 202 and tyrosine 204. It is used to detect and quantify the activated, phosphorylated state of these important signaling proteins.

Whole‐cell extracts were prepared by lysing cells with RIPA buffer (50 mM Tris‐HCl [7.4], 150 mM NaCl, 1% Triton X‐100, 0.5% sodium deoxycholate, 0.1% SDS) containing 5 mM sodium vanadate, 5 mM NaF, and complete EDTA‐free protease inhibitor (Roche) for 30 minutes at 4°C. Insoluble materials were removed by centrifugation. Western blotting was carried out using standard methods. The following antibodies were used: rabbit anti‐phospho‐EGFR (Y1068) (1:3000; Cell Signaling #2237), mouse anti‐EGFR (1:3000; Cell Signaling #2239), rabbit anti‐phospho‐AKT (S473) (1:3000; Cell Signaling #9271), rabbit anti‐AKT (1:3000; Cell Signaling #9272), rabbit anti‐phospho‐ERK1/2 (T202/Y204) (1:3000; Cell Signaling #9101), rabbit anti‐ERK1/2 (1:10 000; Santa Cruz sc‐93), mouse anti‐actin (1:1000; Sigma C7207), anti‐mouse IgG‐HRP (1:10 000; GE Healthcare NA9310), and anti‐rabbit IgG‐HRP (1:10 000; GE Healthcare NA9340).

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.
