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.

SDS-PAGE and Protein Transfer
The following is a general protocol for sample preparation using 5x105 SK-N-MC cells per well in a 6-well plate:
1. Aspirate media from cultures. Wash cells with PBS. Aspirate supernatant.
2. Lyse cells by adding 100 μl SDS Sample Buffer per well in a 6-well plate and immediately scrape the cells off the plate and transfer the extract to a microfuge tube. Keep on ice.
3. Sonicate for 2 s to shear DNA and reduce sample viscosity.
4. Heat sample to 95-100°C for 5 min. Cool on ice.
5. Microcentrifuge for 5 min.
6. Load 20 μl onto SDS-PAGE gel (10 cm x 10 cm).
7. Electrotransfer to nitrocellulose membrane.

We recommend using 10 μl unphosphorylated Cdk1 protein as a negative control and 20 μl SK-N-MC cell lysate as positive control.

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.

Detection of Proteins
Chemiluminescence.

Variables associated with assay conditions will dictate the proper working dilution.

DescriptionRabbit polyclonal antibody purified by protein A chromatography, adsorbed against non-phosphopeptide corresponding to the immunogen phosphorylation site, followed by immunoaffinity chromatography. Recognizes the ~34 kDa Cdk1 protein, phosphorylated on Tyr15.
BackgroundEntry of all eukaryotic cells into M-phase of the cell cycle is regulated by activation of Cdk1 kinase. Activation of Cdk1 is controlled at several steps including cyclin binding and phosphorylation of threonine161. However, the critical regulatory step in activating Cdk1 during progression into mitosis appears to be dephosphorylation of Tyr15 and Thr14. Phosphorylation at Tyr15 and inhibition of Cdk1 is carried out by WEE1 and MIK protein kinases while Tyr15 dephosphorylation and activation of Cdk1 is carried out by the Cdc25 phosphatase.
