Recommended Protocol for Immunoblotting

Solutions and Reagents
• Transfer Buffer: 25 mM Tris base, 0.2 M glycine, 20% methanol, pH 8.5
• SDS Sample Buffer: 62.5 mM Tris-HCl, pH 6.8, 2% SDS, 10% glycerol, 50 mM DTT, 0.1% bromophenol blue.
• 10X TBS (Tris-buffered saline): To prepare 1 liter, 24.2 g Tris base, 80 g NaCl, adjust pH to 7.6 with HCl. Dilute 1:10 for use.
• Blocking Buffer: 1X TBS, 0.1% Tween®-20 detergent with 5% non-fat dry milk.
• Primary Antibody Dilution Buffer: 1X TBS, 0.1% Tween®-20 detergent with 5% BSA
• Wash Buffer (TBST): 1X TBS, 0,1% Tween®-20 detergent

Blotting Membrane
Nitrocellulose or PVDF membranes may be used.

Protein Blotting
A general protocol for sample preparation using 2x106 PC12 cells per well in a 6-well plate is as follows:

1. Culture cells in medium containing 0.5% FBS for 2 days. We recommend plating cells directly in 0.5% FBS media to reduce basal levels of MAP kinase phosphorylation.
2. Aspirate media. Add fresh 0.5% FBS media. Culture for 2 h.
If cells are grown at high density, changing media before treating cells with regulator reduces basal MAP kinase phosphorylation due to factors secreted by the cells.
3. Aspirate media. Treat cells by adding fresh 0.5% FBS media containing regulator for desired time.
4. Aspirate media from cultures; wash cells with PBS; aspirate.
5. Lyse cells by adding 100 µl SDS Sample Buffer per well and immediately scrape the cells off the plate and transfer the extract to a microfuge tube. Keep on ice.
6. Sonicate for 2 s to shear DNA and reduce sample viscosity.
7. Heat sample to 95-100°C for 5 min. Cool on ice.
8. Microcentrifuge for 5 min.
9. Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm).
10. Electrotransfer to nitrocellulose membrane.
As controls, we recommend using 10 µl of phosphorylated (Cat. No. 454855) and nonphosphorylated
(Cat. No. 454852) MAP kinase control proteins.

Membrane Blocking, Gel and Antibody Incubations
1. After transfer, wash membrane with 25 ml TBS for 5 min at room temperature.
2. Incubate membrane in 25 ml of Blocking Buffer for 1-3 h at room temperature or overnight at 4°C.
3. Wash 3 times for 5 min each with 15 ml of TBST.
4. Incubate membrane and primary antibody (at the appropriate dilution) in 10 ml Primary Antibody Dilution
Buffer with gentle agitation overnight at 4°C.
5. Wash 3 times for 5 min each with 15 ml of TBST.
6. Incubate membrane with conjugated secondary antibody at the appropriate dilution in 10 ml Blocking Buffer with gentle agitation for 1 h at room temperature.
7. Wash membrane as in step 5.

DescriptionRabbit polyclonal antibody purified by protein A and immunoaffinity chromatography. Recognizes the ~42-44 kDa ERK1 and ERK2 proteins.
Backgroundp44 and p42 MAP kinases (ERK1 and ERK2) function in a protein kinase cascade that plays a critical role in the regulation of cell growth and differentiation. MAP kinases are activated by a wide variety of extracellular signals including growth and neurotrophic factors, cytokines, hormones and neurotransmitters. Activation of MAP kinases occurs through phosphorylation of threonine and tyrosine (amino acids 202 and 204 of human MAP kinase (ERK1) at the sequence T*EY* by a single upstream MAP kinase kinase (MEK)).
