Delta receptors density

Both groups used expression cloning to screen cDNA libraries obtained from NG 108-15 mouse neuroblastoma-rat glioma hybridoma cells. These cells were a logical choice for delta opioid receptor cloning efforts, since they express high density of delta receptors and can be produced in great quantities in cell culture.
