Abstract: Disclosed are vaccines containing both a DNA sequence encoding FIV gag protein and a DNA sequence encoding FIV env protein. The gag and env proteins are preferably expressed by baculovirus expression systems containing the DNA sequences encoding the FIV env and gag proteins or in feline herpes virus vectors containing the DNA sequences encoding the FIV env and gag proteins. Also disclosed are combined mucosal/parenteral, mucosal/mucosal and parenteral/parenteral inoculation methods.

Abstract: Disclosed are expression vectors useful as vectors in recombinant methods to facilitate expression of exogenous genes in E. coli. Specifically, the disclosed expression vector has the following elements in operable linkage: the PL6m promoter, the TAT32 ribosome binding site and a gene encoding a heterologous polypeptide, Also disclosed are E. coli host cells transformed with this expression vector.

Abstract: A modified gene coding for the human D4 dopamine receptor has been synthesized by chemo-enzymatic methods. The nucleotide sequence of the D4 dopamine receptor gene was changed to reduce the G+C content and to eliminate intronic sequences, while maintaining the published amino acid sequence. Using gene splicing by overlap extension and PCR amplification of long oligonucleotides (>200 bases), 3 synthetic fragments of about 400 base pairs each were amplified, from which the full length gene was assembled. Stable expression of this gene has been achieved in CHO-K1 cells, using an inducible expression system, and in HEK293 cells.

Abstract: This invention provides a method of using somatotropin to enhance the reproductive performance in cattle by commencing administration during the early postpartum period. Following one aspect of the invention, somatotropin (5 mg/day) is administered starting at five days postpartum, continuing until the animal becomes pregnant or until about 100 days postpartum.

Abstract: The present invention is based upon the discovery that proteins made from genes that include the CD4 sequence in its cDNA can make additional polypeptides as a result of internal translation initiation. This invention is thus directed to DNA sequences which eliminate internal initiation expression in sCD4.
