the binding to these cells during an incubation with 5 nm ( 3h ) nd4-11 alpha-msh at 37 degrees c is maximal at 0-30 min , 22 fmol/10 ( 6 ) cells , but declines to 40 % of this value at 4 hr . in the presence of 5 nm ( 3h ) nd4-11 alpha-msh at 37 degrees c , the acid soluble ( cell surface ) radioactivity decreased rapidly from 11.4 fmol/10 ( 6 ) cells at 5 min to 4.6 fmol/10 ( 6 ) cells at 4 hr .
