Product overview
HeLa cells are an adherent human epithelial cell line derived from a cervical carcinoma. HeLa cells were lysed with 1% SDS in the prescence of protease and phosphatase inhibitors. Protein concentration of the extract was determined by BCA assay. The extract is suitable for use in SDS-PAGE and Western blotting.
PMA-treated HeLa lysate is designed for use as a western blot positive control when studying signaling cascades downstream of PKC. Cells were treated with 200 nM PMA for 1 hour after overnight serum starvation. Untreated cells were grown under the same conditions and treated instead with DMSO (PMA diluent as used to generate the treated lysate).

Notes
PMA (phorbol 12-myristate 13-acetate) also known as TPA (12-O-Tetradecanoylphorbol 13-acetate), is a potent activator of protein kinase C (PKC), a calcium-activated, phospholipid- and diacylglycerol (DAG)-dependent serine/threonine-protein kinase. PKC is involved in positive and negative regulation of cell proliferation, apoptosis, differentiation, migration and adhesion, tumorigenesis, cardiac hypertrophy, angiogenesis, platelet function and inflammation, by directly phosphorylating targets such as RAF1, BCL2, CSPG4, TNNT2/CTNT, or activating signaling cascade involving MAPK1/3 (ERK1/2) and RAP1GAP.

Western Blot Validation
HeLa cell cultures were serum-starved overnight and treated with 200nM of PMA for 1 hour at 37°C. 40µg of cell lysate was run on a 4-20% gradient gel then transferred to a PVDF membrane. All blocking and antibody incubation steps were done in 5% milk, 20 mM Tris-HCl, 0.1% TWEEN-20. Primary antibodies: RSK1p90 total: 1:1000 ab32114 RSK1p90 pSer380: 1:500 ab32203 Actin beta: 1µg/mL ab8226 Secondary antibodies: Goat polyclonal to Mouse IgG – H&L – Pre-Adsorbed (HRP) at 1/10000. Goat polyclonal to Rabbit IgG – H&L – Pre-Adsorbed (HRP) at 1/10000.

Optiblot Blue stainOptiblot Blue stain HeLa cell cultures were serum-starved overnight and treated with 200 nM of PMA for 1 hour at 37°C. 40 µg of cell lysate was run on a 4-20% gradient gel then stained with Optiblot Blue (ab119211) for 2 hours at room temperature. Gel was destained using nanopure water for 24 hours.
