Recombinant SP140 (688-862) protein gel. SP140 (688-862) protein was run on an SDS-PAGE gel and stained with Coomassie blue.
Recombinant SP140 (688-862) activity using AlphaScreen. SP140 (688-862) was used in an AlphaScreen® assay to generate a titration curve demonstrating the signal response in the presence of modified peptide substrate at increasing protein concentrations.
