Cells expressing a substantial number of surface high affinity HBGF receptors but relatively few low affinity HBGF binding sites and system for assaying binding to HBGF receptor
Cells expressing a substantial number of surface high affinity HBGF receptors but relatively few low affinity HBGF binding sites and system for assaying binding to HBGF receptor
A homogeneous population of cells having on average (1) a number of cell surface low-affinity heparin-binding growth factor (HBGF) sites per cell less than 20% of the number of such binding sites found on wild-type CHO-K1 cells (ATCC Accession No. CCL61), and at least three times the number of cell surface high-affinity HBGF receptors per cell found on such CHO-K1 cells; and an assay system utilizing such cells.
