Hughes Charles Joseph: Vehicule route finding system.. British Telecomm, October 31, 1984: EP0123562-A1 (91 worldwide citation)

A vehicle route finding system whereby a vehicle borne receiver (10) picks up signals from a radio navigation system (14, 15, 16, 23), such as the Loran-C system, and transmits data related to its location to a central station, via the data channel on a radiotelephone link. At the central station a ...

Singh Arjun: Process for expressing heterologous protein in yeast, expression vehicles and yeast organisms therefor.. Genentech, October 31, 1984: EP0123544-A2 (91 worldwide citation)

The isolation of the yeast alpha -factor genes is described. The promoter and signal peptide portions are isolated and joined to DNA coding for proteins heterologous to yeast in a plasmid which is used to transform yeast cells. The yeast expresses the heterologous DNA and processes and secretes the ...

Bitter Grant A: Yeast cell transformation vectors.. Amgen, October 31, 1984: EP0123294-A1 (68 worldwide citation)

Disclosed are recombinant methods and materials for use in securing production of exogenous (e.g., mammalian) polypeptides in yeast cells wherein hybrid precursor peptides susceptible to intracellular processing are formed and such processing results in secretion of desired polypeptides. In a presen ...

Barr Philip J, Merryweather James P, Mullenbach Guy, Urdea Mickey S: Hybrid dna synthesis of mature insulin-like growth factors.. Chiron, October 31, 1984: EP0123228-A2 (56 worldwide citation)

Methods and compositions are provided for efficient production of human insulin-like growth factor. Synthetic IGF I and IGF II genes are joined to leader and processing signals which provide for expression and secretion of the gene product in yeast. Enhanced yields of the product may then be recover ...
