Product Usage Information

As controls, CST recommends using 10 µl of GST-cdc2 negative control protein and 20 µl of the positive control SK-N-MC cell extract.

Note: Boil both negative control and positive control for 2-4 minutes prior to loading on an SDS-PAGE gel.

Storage

Store at -20°C.

Product Description

Phosphorylated cdc2 Control Protein: SK-N-MC total cell extracts, treated with hydroxyurea for 22 hours to induce cdc2 (Tyr15) phosphorylation, serve as a positive control for Western blotting experiments.

Nonphosphorylated cdc2 Control Protein: A glutathione S-transferase (GST)-cdc2 fusion protein serves as a negative control for monitoring antibody phosphoselectivity for Western blotting experiments. Molecular weight of GST-cdc2 fusion protein is 32 kDa.

Background

The entry of eukaryotic cells into mitosis is regulated by cdc2 kinase activation, a process controlled at several steps including cyclin binding and phosphorylation of cdc2 at Thr161 (1). However, the critical regulatory step in activating cdc2 during progression into mitosis appears to be dephosphorylation of cdc2 at Thr14 and Tyr15 (2). Phosphorylation at Thr14 and Tyr15, resulting in inhibition of cdc2, can be carried out by Wee1 and Myt1 protein kinases (3,4). The cdc25 phosphatase may be responsible for removal of phosphates at Thr14 and Tyr15 and subsequent activation of cdc2 (1,5).
