Anti phosphop44 42 map kinase thr202 tyr204 antibody anti p42 44 p

Manufactured by Cell Signaling Technology

The Anti-phospho-p44/42 MAP kinase (Thr202/Tyr204) antibody (Anti-p42-44-P) is a protein-specific antibody that recognizes the phosphorylated forms of p44/42 MAPK (Erk1/2) at Thr202 and Tyr204 residues. It is used for the detection and analysis of the activated, phosphorylated state of these MAPK proteins.

For the Mkc1p phosphorylation blot, overnight cultures were diluted in fresh YEPD media to an OD600 of 0.3 and grown until they reached an OD600 of 1 at 37°C and 200 rpm. Samples were treated with 5 μg ml−1 tunicamycin for 2 hr before they were recovered. The procedures used for cell collection, lysis, protein extraction, fractionation by SDS-PAGE and transfer to nitrocellulose membranes have been previously described (Martín, Arroyo, Sánchez, Molina, & Nombela, 1993 (link)). Anti-phosphop44/42 MAP kinase (Thr202/Tyr204) antibody (Anti-p42–44-P) (Cell Signalling Technology, Inc.) was used to detect dually phosphorylated Mkc1 and Cek1 MAPKs, and polyclonal anti-Mkc1 antibodies were used for Mkc1 detection (Federico Navarro-García, Eisman, Fiuza, Nombela, & Pla, 2005 (link)). Blot imaging was done by using an Odyssey fluorescence imager (LI-COR) and quantified using Image Studio Lite (LI-COR).

For the Mkc1p phosphorylation blot, overnight cultures were diluted in fresh YEPD media to an OD600 of 0.3 and grown until they reached an OD600 of 1 at 37°C and 200 rpm. Samples were treated with 5 μg ml−1 tunicamycin for 2 hr before they were recovered. The procedures used for cell collection, lysis, protein extraction, fractionation by SDS‐PAGE and transfer to nitrocellulose membranes have been previously described (Martín, Arroyo, Sánchez, Molina, & Nombela, 1993). Anti‐phospho‐p44/42 MAP kinase (Thr202/Tyr204) antibody (Anti‐p42‐44‐P) (Cell Signalling Technology, Inc.) was used to detect dually phosphorylated Mkc1 and Cek1 MAPKs, and polyclonal anti‐Mkc1 antibodies were used for Mkc1 detection (Federico Navarro‐García, Eisman, Fiuza, Nombela, & Pla, 2005).

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.
