Abstract

Two cDNAs encoding two human receptors for retinoic acid (RA), RAR-alpha and RAR-beta, have been characterized recently. Synthetic peptides corresponding to the cDNA-deduced amino acid sequences unique to RAR-alpha and RAR-beta were used to generate anti-RAR-alpha antiserum (SP171) and anti-RAR-beta antisera (SP172 and SP248). The specificity of these antisera was confirmed both by immunocytochemical detection of these receptors in COS-1 cells transfected with RAR-alpha and RAR-beta expression vectors and by immunoblot analyses performed with whole extracts of these cells. We also demonstrate that these antisera recognize RAR-alpha and RAR-beta endogenously expressed in the RA-responsive human promyelocytic leukemia cell line HL-60.
