by mixing , in pairs , photolabeled proteins from ( a ) intact human cells derived from giant cell tumors of bone , ( b ) intact human fibroblasts , and ( c ) canine renal cortical membranes , the receptors ( or their binding subunits ) for pth were compared directly and found to be identical in terms of molecular size ( as determined by the migration position on nadod-so4-polyacrylamide gels ) across species ( dog and human ) and target tissue ( bone , skin , and kidney ) .
