Abstract

Polyclonal antibodies were generated against two synthetic peptides corresponding to sequences from the DNA-binding domain of steroid receptors. The sequence for peptide 1 (13 amino acids) lies between the two putative metal-binding loops of the conserved cysteine region while the sequence for peptide 2 (12 amino acids) lies within one loop. Peptide antibodies were generated by injecting rabbits with peptide conjugated to bovine serum albumin. By Western blot analysis, antibodies to peptide 2 recognized chick and human progesterone receptor and human glucocorticoid receptor, but peptide 1 antibodies did not. No cross-reactivity with native chick progesterone receptor was detected with either anti-peptide. These findings suggest that the epitopes for peptide 2 antibodies, and possibly for peptide 1 antibodies, are inaccessible to antibody in the native receptor.
