    摘要: A tyrosine kinase substrate is described. The tyrosine kinase substrate comprises a fusion protein which comprises a protein for labeling and a specific peptide fused with the protein for labeling. The specific peptide has an amino acid sequence including a glutamic acid residue and a tyrosine residue. The tyrosine kinase substrate is capable of being phosphorylated by a plurality of kinds of tyrosine kinases.

    摘要: A method for assessing the proliferation inhibiting effect of a receptor tyrosine kinase inhibitor is described. In the method, a cytoplasm is separated from a tumor cell to prepare a sample containing various receptor tyrosine kinases. The prepared sample is treated with the inhibitor. The receptor tyrosine kinases in the treated sample, and a substrate for at least two kinds of receptor tyrosine kinases are contacted. The phosphorylated substrate is detected, and the activity value of the receptor tyrosine kinases is measured based on the detection result. The proliferation inhibiting effect is assessed based on the resulting activity value.

    摘要: A method for measuring the activity of a receptor kinase present in a cell membrane of a cell is described. The method comprises steps of preparing a sample containing the receptor kinase by separating a cytoplasm from the cell, contacting the receptor kinase in the sample with a substrate to phosphorylate the substrate with the activity of the receptor kinase, binding a labeling substance to the phosphorylated substrate, and measuring the activity of the receptor kinase based on a result of detection of the labeling substance bound to the phosphorylated substrate.
