Synthetic genes for relaxin, the expression thereof, corresponding plasmid recombinants and transformed cells and the production thereof are disclosed.
Relaxin has an application in controlling labour in pregnancy.
Modified beta interferons containing amino acid substitutions in the beta interferon amino acids 80 to 113 are described. These modified beta interferons exhibit changes in the antiviral, cell growth regulatory or immunomodulatory activities when compared with unmodified beta interferon.
Modified beta interferons containing amino acid substitutions in the beta interferon amino acids 115 to 145 are described. These modified beta interferons exhibit changes in the antiviral, cell growth regulatory or immunomodulatory activities when compared with unmodified beta interferon.
Modified beta interferons containing amino acid substitutions in the beta interferon amino acids 1 to 28 are described. These modified beta interferons exhibit changes in the antiviral, cell growth regulatory or immunomodulatory activities when compared with unmodified beta interferon.

The present invention is directed to a process for amplifying and detecting any target nucleic acid sequence contained in a nucleic acid or mixture thereof. The process comprises treating separate complementary strands of the nucleic acid with a molar excess of two oligonucleotide primers, extending the primers to form complementary primer extension products which act as templates for synthesizing the desired nucleic acid sequence, and detecting the sequence so amplified. The steps of the reaction may be carried out stepwise or simultaneously and can be repeated as often as desired. In addition, a specific nucleic acid sequence may be cloned into a vector by using primers to amplify the sequence, which contain restriction sites on their non-complementary ends, and a nucleic acid fragment may be prepared from an existing shorter fragment using the amplification process.
