| Description : |
MSK1 (mitogen- and stress-activated protein kinases-1, ribosomal protein S6 kinase, 90kDa, polypeptide 5) and MSK2 (mitogen- and stress-activated protein kinases-2, ribosomal protein S6 kinase, 90kDa, polypeptide 4) are activated in vitro by MAPK2/ERK2 or SAPK2/p38. Endogenous MSK is activated by UV radiation, oxidative stress, and other cell-damaging stimuli. MSK may mediate the growth factor and stress-induced activation of CREB. |

| Storage : |
1 year at -70 centigrade. |
| Handling Advice : |
Rapidly thaw the vial under cold water and immediately place on ice. Aliquot unused material into prechilled micro-centrifuge tubes and immediately snap-freeze the vials in liquid nitrogen prior to re-storage at -70 centigrade. |
| Use/Stability : |
On receipt of material store at -20 centigrade. Unopened reagent is stable for a minimum of 1 year from date of shipment when stored at recommended storage temperature. Avoid repeat freeze/thaw cycles. For maximum recovery of product, centrifuge original vial prior to removing the cap. |
