Abstract: A method of producing an erythroid cell which is substantially undifferentiated but which is capable of expressing a heterologous protein under the control of a globin promoter thereof, which method comprises maintaining growing uninduced erythroid cells in culture for sufficient period of time that the protein is expressed, and isolating a subclone which expresses said protein. Erythroid cells produced by the method, and methods of detecting the interaction of an insect G-protein coupled receptor with an endogenous signaling cascade of erythroid cells are also described and claimed.

Abstract: This invention relates to disgnostic methods for the detection of one or more cytochrome b mutations in fungi at the position corresponding to Saccharomyces cerevisiae cytochrome b residue 129 that leads to resistance to strobilurin analogues or compounds in the same cross resistance group using any (or a) single nucleotide polymorphism detection technique, preferably using either an allele specific amplilication technique such as the amplification refractory mutation system (ARMS) or preferably using an allele selective hybridisation probe technique such as Molecular Beacons or TaqMan. The invention also relates to mutation specific oligonucleotides for use in the method and to diagnostic kits containing these (oligonucleotides.
