Kinase Assay

Cell-free kinase assays are done in quadruplicate with 1 μM ATP to determine the IC50 values of KRN951 against a variety of recombinant receptor and nonreceptor tyrosine kinases[1].

Cell Assay
[1]

Cell-based assays are done to determine the ability of KRN951 to inhibit ligand-dependent phosphorylation of receptor tyrosine kinases. Briefly, the cells are starved overnight in appropriate basic medium containing 0.5% fetal bovine serum (FBS). Following the addition of KRN951 or 0.1% DMSO, the cells are incubated for 1 hour and then stimulated with the cognate ligand at 37°C. Receptor phosphorylation is induced for 5 minutes except for VEGFR3 (10 minutes), c-Met (10 minutes), and c-Kit (15 minutes). All the ligands used in the assays are human recombinant proteins, except for VEGF-C, a rat recombinant protein. Following cell lysis, receptors are immunoprecipitated with appropriate antibodies and subjected to immunoblotting with phosphotyrosine. Quantification of the blots and calculation of IC50 values are carried out[1].

Animal Administration
[1]

Mice: Cancer cells are s.c. inoculated into the right flank of the athymic rats. Once established, tumors of 1,500 mm3 are surgically excised and smaller tumor fragments (20-30 mg) are s.c. implanted in the right flank of irradiated rats. Oral administration of KRN951 (0.2 or 1 mg/kg) or vehicle is initiated at the day of randomization (day 0). Tumor volume is measured twice weekly with Vernier calipers, and calculated[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
