    摘要: DNA encoding an endothelin receptor shown in SEQ ID NO: 1 or 2 in the Sequence Listing is isolated from cDNA which is prepared from poly(A)⁺RNA derived from a human placenta. In addition, an expression vector containing the DNA and a transformant containing the expression vector are obtained. An endothelin receptor is obtained by culturing this transformant. A receptor shown in SEQ ID NO: 1 is an ET A -receptor which has a high affinity for endothelins 1 and 2, especially for the endothelin 1. A receptor shown in SEQ ID NO: 2 is an ET B -receptor which has an affinity for endothelins 1, 2 and 3 with no selectivity.

    摘要: The radioactive iodine compound of this invention or an intermediate for preparing the compound is represented by the following formula (I):

    wherein R is H or ¹²⁵I.
    The radioactive compound can readily introduce a radioactive isotope element such as ¹²⁵I into an antibody molecule without damaging the activity of the antibody molecule. Therefore, the compound can preferably be used to label an antibody of immunoradiometric assay, and allow a higher degree of measurement sensitivity.
