      Applications
      Data setup Error. Pagelet <collection_feature_application_id-KINASE> not found.
      Application CommentsMaterials Needed:
      • Protein tyrosine Kinase (such as p60c-src, Cat# PK03)
      • [γ-32P]ATP (10 mCi/ml)
      • Kinase Assay Buffer: 50 mM HEPES, pH 7.5 containing 0.1 mM EDTA and 0.015% Brij® 35 detergent
      • Kinase Dilution Buffer: Kinase assay buffer containing 0.1 mg/mL BSA and 0.2% β-mercaptoethanol (note: b-mercaptoethanol is required for src kinase activity)
      • ATP Mix: 0.15 mM ATP, 30 mM MgCl2 and 200 µCi [γ-32P]ATP per ml in kinase assay buffer
      • Phosphoric acid
      • Acetone
      • P81 Ion Exchange Chromatography paper (i.e. Whatman #3698915)

      Procedure:
      • Dilute kinase protein solution in Kinase Dilution Buffer if of sufficiently high concentration or, alternatively, buffer exchange the kinase protein of interest into the Kinase Dilution Buffer.
      • Mix 10 µl diluted kinase with 10 µl Raytide™ EL (1 mg/ml solution in Kinase Assay Buffer).
      • Start the reaction by adding 10 µl of ATP Mix.
      • Incubate at 30°C for 30 min.
      • Stop the reaction by adding 120 µl of 10% phosphoric acid. Vortex and apply 120 µl onto a square (2 cm x 2 cm) of P81 paper.
      • Wash papers extensively in 0.5% phosphoric acid. Wash once with acetone. Dry and quantitate by liquid scintillation counting. (Phosphorylated Raytide™ EL will stick, while ATP will wash off the papers).

      DescriptionProtein Tyrosine Kinase substrate Raytide™ EL ("EL" for "enhanced labeling") is a modified gastrin analog. Raytide™ EL differs from the standard Raytide™ substrate (Cat. No. PK02); in that it provides a higher labeling efficiency when used as either a kinase or a phosphatase substrate. The carboxyl end of the peptide contains acidic and hydrophilic amino acid residues, while the amino terminus contains basic amino acids. In phosphoric acid the amino end is positively charged and binds to phosphocellulose paper (p81 Whatman). The distance between the two charged ends of the peptide prevents neutralization. Additionally, the peptide maintains an unfolded state and functions as an excellent substrate for protein tyrosine kinases (see procedure section) and tyrosine phosphates (Nature 350:359-362, 1991).
