Abstract: A method for determining the presence and location in animal or plant tissue of a specific polynucleotide population comprising: (a) preparing a section of the tissue to be examined; (b) contacting the tissue section under hybridization conditions with a synthetic, labelled oligonucleotide probe which is complementary to a representative portion of the target polynucleotide; (c) removing unhybridized probe material from the tissue section; and (d) detecting or identifying the locations in the tissue section where labelling or hybridization of the labelled probe has occurred. A diagnostic kit for use in performance of the above method is also disclosed.

Abstract: Oligonucleotide-polyamide conjugates of the formula X--L--Y, where X is a polyamide, Y is an oligonucleotide, and L is a linker which forms a covalent bond with the amino-terminus of the polyamide X and the 3' phosphate group of the oligonucleotide Y. Conjugates may be synthesized by assembling a polyamide on a solid support matrix, adding a suitable linker molecule, followed by synthesis of the oligonucleotide. Methods for detecting specific polynucleotides with oligonucleotide-polyamide conjugates are also described.

Abstract: DNA sequence of S-genes which encode S-proteins and control the self-incompatibility reaction in gametophytic self-incompatible plants have been identified. The DNA sequence encoding several S-proteins of N. alata and their attendant signal sequences are specifically provided. Regulatory sequences which direct expression of the S-genes in reproduction tissue of self-incompatible plants have also been identified. A method for the identification and isolation of cDNA and genomic DNA coding sequences of the S-genes is described.

Abstract: A method for the synthesis of porcine relaxin or modified forms or analogues thereof, which comprises the steps of reducing a mixed solution of the S-sulfonated A and B peptide chains, or modified forms or analogues thereof; precipitating the reduced peptides with acetone; washing the mixed peptides; oxidizing the mixed peptides in the presence of aqueous sodium chloride; and isolating the relaxin thus produced.Also claimed are modified forms and analogues of porcine relaxin analogues which comprise shortened forms of the natural B and/or A peptide chains, and/or in which one or both of A and B chains in the full length or shortened form has been chemically modified.

Abstract: Resin peptides useful in the preparation of peptides having biological activity, and particularly such resin peptides containing R--CH.sub.2 --O--Phe--Asn at one end of an amino acid chain, R being the resin and Phe and Asn being the residues of the amino acids phenylalanine and asparagine; and processes for the preparation of such resin peptides. Resin peptides are disclosed which contain amino acid chains identical with the amino acid chains of natural peptides having biological activity. Other resin peptides are disclosed which contain amino acid chains in which the amino acid residues differ in kind and sequence from amino acid chains of natural biologically active peptides but from which peptides having biological acitivity may be derived.
