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: 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.
