    摘要: A novel classes of neural axon outgrowth promoting and orienting proteins, nucleic acids encoding such proteins and receptors which selectively bind such proteins are disclosed. The disclosed neural axon outgrowth promoting and orienting proteins include the laminin-related p75/p78 family; a family of vertebrate proteins which promote axon outgrowth and/or orientation, and p75/p78 family-specific receptors, including receptors found on spinal nerve axons, especially growth cones. Also disclosed are agents including peptides derived from the disclosed neural axon outgrowth promoting proteins capable of effecting axon outgrowth, orientation and regeneration. These agents provide small molecular weight modulators of nerve cell growth useful in the treatment of neurological disease and injury. The disclosed compositions also find use variously in screening chemical libraries for regulators of axon outgrowth and orientation, in genetic mapping, as probes for related genes, as diagnostic reagents for genetic neurological disease and in the production of specific cellular and animal systems for the development of neurological disease therapy.

    摘要: The invention provides methods for isolating cell-type specific mRNAs by selectively isolating ribosomes or proteins that bind mRNA in a cell type specific manner, and, thereby, the mRNA bound to the ribosomes or proteins that bind mRNA. Ribosomes, which are riboprotein complexes, bind mRNA that is being actively translated in cells. According to the methods of the invention, cells are engineered to express a molecularly tagged ribosomal protein or protein that binds mRNA by introducing into the cell a nucleic acid comprising a nucleotide sequence encoding a ribosomal protein or protein that binds mRNA fused to a nucleotide sequence encoding a peptide tag. The tagged ribosome or mRNA binding protein can then be isolated, along with the mRNA bound to the tagged ribosome or mRNA binding protein, and the mRNA isolated and further used for gene expression analysis. The methods of the invention facilitate the analysis and quantification of gene expression in the selected cell type present within a heterogeneous cell mixture, without the need to isolate the cells of that cell type as a preliminary step.

    摘要: Nucleic acids are made by converting a primed single-stranded DNA to a double-stranded DNA by a method comprising the step contacting the single-stranded DNA with a DNA polymerase having 5′ exonuclease activity under conditions whereby the DNA polymerase converts the-single stranded DNA to the double-stranded DNA, wherein the single-stranded DNA is primed with oligonucleotide primer comprising a sequence complementary to the 3′ end of the single-stranded DNA, and at least one of the 5′ end of the primer and the single-stranded DNA comprises an RNA polymerase promoter joined to an upstream (5′) flanking moiety which protects the promoter from the 5′ exonuclease activity of the DNA polymerase.
