Vaccines against Herpes Simplex virus containing recombinant polypeptides which are cross-reactive with glycoprotein D of the virus, methods for their production using recombinant DNA techniques in yeast, and methods for the use of the vaccine are provided. E. coli strains HB101 containing plasmids pYHS 109 and pYHS118 were deposited at the American Type Culture Collection on Jul. 11, 1984, and granted accession nos. 39762 and 39763, respectively.

Recombinant herpes simplex gD vaccine

A DNA having a base sequence coding for human epidermal growth factor has been synthesized in blocks, and cloned. Novel recombinant DNA transfer vectors containing said cloned DNA have been constructed. The codon usage of the sequence reflects the codon bias of yeast. The DNA sequence is useful for the large scale synthesis of human epidermal growth factor in yeast cells or microorganisms transformed by said recombinant DNA transfer vectors.

Gene for human epidermal growth factor and synthesis and expression

Methods and compositions are provided for efficient production of polypeptides having insulin activity. The proinsulin gene is joined to secretion and processing signals for expression and secretion in yeast. The product may be obtained in enhanced yield in the nutrient medium. Cell line pyinse was deposited at the A.T.C.C. on Apr. 6, 1983 and given Accession No. 20670.

Hybrid DNA synthesis of insulin

Methods and compositions are provided for efficient production of polypeptides having insulin activity. The proinsulin gene is joined to secretion and processing signals for expession and secretion in yeast. The product may be obtained in enhanced yield in the nutrient medium. Cell line AB103(PYinsl) was deposited at the A.T.C.C. on Apr. 6, 1983 and given Accession No. 20,670.

Alpha factor leader sequence directed secretion of insulin

Methods and compositions are provided for rapid detection of nucleic acid sequences. The method employs two reagent sets. The first set is a labelling set comprising: (1) a first nucleic acid sequence probe having an analyte complementary region and a first recognition sequence region and (2) a labelled sequence complementary to the first recognition sequence region. The second set is a capturing set comprising: (1) a second nucleic acid sequence probe having an analyte complementary region and a second recognition sequence region, (2) a specific binding pair member conjugated to a sequence complementary to the second recognition sequence, and (3) a separating means to which is bound a complementary specific binding pair member. The sample and probes are combined under annealing conditions, followed by addition of the other reagents, separation of the bound label from the supernatant and detection of the label in either phase.

Solution phase nucleic acid sandwich assay

Methods for diagnosis employing polynucleotides having oligonucleotide sequences substantially homologous to a sequence of interest, where the presence or absence of hybridization at a predetermined stringency provides for the release of a label from a support. Particularly, various techniques are employed for binding a label to a support, whereupon cleavage of either a single or double strand, a label may be released from a support, where the release of the label can be detected as indicative of the presence of a particular oligonucleotide sequence in a sample. The method finds use in diagnosis of disease, genetic monitoring, and analyzing nucleic acid mixtures.

Polynucleotide determination with selectable cleavage sites

Methods and compositions are provided for the efficient production in yeast of polypeptides which are immunologically cross-reactive with glycoprotein D of the herpes simplex virus. Synthetic DNA fragments encoding for a portion of the glycoprotein, and the naturally-occurring gene encoding for the glycoprotein and portions thereof, are expressed on plasmids in yeast. Secretion may be provided by including a secretory leader and signal processing sequence derived from the .alpha.-factor gene. Alternatively, the genes may be expressed intracellularly under the transcriptional control of a promoter derived from a gene in the yeast glycolytic pathway. E. coli strains HB101 containing plasmids pYHS109 and pYHS118 were deposited at the American Type Culture Collection on July 11, 1984, and granted accession nos. 39762 and 39763, respectively.

Expression of glycoprotein D of herpes simplex virus

A reactor system and method for synthesizing or degrading polynucleotides and other linear polymers includes a tubular reactor connected to a reagent manifold. The polynucleotide is immobilized on a loosely packed solid-phase support material in the tubular reactor, and reagents are sequentially introduced into the tubular reactor. After each reagent is introduced, the tubular reactor is isolated from the reagent manifold and the reagent agitated by alternately pressurizing the opposite ends of the tubular reactor. The method provides rapid and efficient synthesis of polynucleotides. By connecting two or more tubular reactors to the reagent manifold, a plurality of polynucleotides having different sequences may be synthesized simultaneously.
