Handling
This product is supplied in one (or more) pack size which is freeze dried. Therefore the contents may not be readily visible, as they can coat the bottom or walls of the vial. Please see our FAQs and information page for more details on handling.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Functional Studies - Staurosporine, Protein kinase inhibitor (ab120056)HeLa and Jurkat cells were treated with 1 µM Staurosporine (STS) (ab120056) for 4 hours in complete cell culture media to induce apoptosis and cleaved PARP protein. Untreated and STS treated HeLa and Jurkat lysates were prepared in 1X Cell Extraction Buffer PTR and tested the Cleaved PARP SimpleStepTM ELISA. Raw OD 450 nm values are shown for 500 µg/mL lysate loads.

Functional Studies - Staurosporine, Protein kinase inhibitor (ab120056)Example of IC50 determination. HeLa cells were treated with a dose titration of Staurosporine for 4 hours in complete media. Cells were cultured and treated in a 96-well cell culture microtiter plate. Lysates were prepared by direct in-well lysis without media removal: 2X Cell Extraction Buffer PTR was added to an equal volume of media and then resulting lysate was used directly in the Cleaved PARP SimpleStepTM ELISA assay. Raw values for triplicate measurements are plotted. The calculated IC50 is 0.77 µM.

Functional Studies - Staurosporine, Protein kinase inhibitor (ab120056)Demonstration of Cleaved PARP capture antibody specificity by western blot assay. 20 µg of HeLa extracts that were untreated or treated for 4 hours with 1 µM Staurosporine were analyzed by western blot. The GAPDH blot is included to show the relative loads of each lysate. In the HeLa cell line, Staurosporine treatment is required to detect cleaved PARP protein, as observed in the SimpleStep ELISA.
