fractionation of chromatin into urea-soluble chromosomal nonhistone proteins ( up ) , histones ( hp ) , and dna-associated nonhistone proteins ( np ) revealed that the np fraction from testicular and prostatic chromatin contains organ-specific acceptors for complexes of 5alpha-dihydrotestosterone ( 17beta-hydroxy-5alpha-androstan-3-one ) and its receptor .
