Specifications

Recombinant full-length rat RSK1 (residues 1–end), containing additional N-terminal 6His and HA (YPYDVPDYA) tags. Expressed in baculovirus in Sf21 insect cells
Catalog #R9399-08A
Specific Activity ~4000-5000U/mg, where one unit of RSK1 activity is defined as 1nmol phosphate incorporated into 30uM Rsktide per minute at 30°C with a final ATP concentration of 100uM.
Quality Control TestingKinase Assay: 0.3–3.8ng phosphorylates 30uM RSKtide. Assay background was subtracted from the actual counts to yield the results shown below.
MS Tryptic Fingerprint: Confirmed product identity as rat RSK1 with the translated sequence. SDS-PAGE and Coomassie Stain: Purity was assessed by SDS-PAGE and Coomassie blue staining using 3ug of RSK1 active.
Storage and StabilityAliquot to avoid repeated freezing and thawing and store at -70°C. Aliquots are stable for at least 6 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Handling Recommendations Rapidly thaw the vial under cold water and immediately place on ice. Aliquot unused material into pre-chilled microcentrifuge tubes and immediately snap-freeze the vials in liquid nitrogen prior to re-storage at -70°C.
Molecular Weight89.9kD
SourceRecombinant, rat expressed in Sf21 insect cells
Purity~95%. Purified using Ni2+/NTA-agarose. Activated with p42 MAPK and PDK1, and repurified by glutathione-, heparin-, and Ni2+/NTA-agarose chromatographies.
