Activation Test: Gel Information for MAPK8 (JNK1), Inactive

The coupled MAPK8 activation assay uses active MAP2K7, mutant to Page Description: The SDS- phosphorylate ATF2 substrate. The assay was setup in two states: 1st PAGE and/or Native PAGE MAPK8 by MAP2K7, mutant without 32P-ATP; and 2nd were run on 4-20% Tris-Glycine ATF2 substrate phosphorylation by activated MAPK8 in the presence of Novex® gels (Catalog #: 32P-ATP. The basal activity of MAPK8 was also assayed in the absence of EC6025BOX). MAP2K7, mutant. Lane 1: Invitrogen™ BenchMark™ Protein Ladder (Catalog #: 10747-012).

Dilution Buffer: Lane 2: 1 μg MAPK8 (JNK1), 20 mM Tris (pH 7.5), 0.05% Triton® X−100, 0.1 mg/mL BSA, 2 mM DTT Inactive and 10% Glycerol. Lane 3: 2 μg MAPK8 (JNK1), Assay Conditions: Inactive Both the active and inactive were diluted in dilution buffer and the reaction was set up in two stages. In stage one, MAPK8 (JNK1), Lane 4: 5 μg MAPK8 (JNK1), Inactive (40 μg/mL final concentration) was incubated with either Inactive 400 μg/mL final concentration mutant MAP2K7 or with dilution buffer to determine activated and basal MAPK8 (JNK1), Inactive activity Lane 5: 10 μg MAPK8 (JNK1), respectively. The assays were performed in 50 mM Tris (pH 7.5), Inactive ® 10 mM MgCl2, 1 mM EGTA, 2 mM DTT, 0.1% Triton X–100, 250 μM ATP for 30 minutes at 30°C. In stage two, 5 μL of the above reaction mix was Purity: transferred to 25 μL of reaction mix containing 50 mM Tris (pH 7.5), 10 mM 90% as determined by a Coomassie® blue stained SDS-PAGE gel. ® MgCl2, 1 mM EGTA, 2 mM DTT, 0.1% Triton X–100, 200 μM ATP, 0.1 μg/mL ATF2 substrate per reaction and trace [32P]–γ–ATP and Molecular Weight: incubated for 10 minutes at 30°C. 47.6 kDa. Calculated from the protein sequence(s). Mass Spectrometry: MAPK8 (JNK1), Inactive was subjected to proteolytic digest followed by mass spec analysis. The resulting MS/MS data verified MAPK8 (JNK1) identity by comparison against the sequence(s) of the recombinant protein.
