  • Patent number: 5459253
    Abstract: A method kit for purification of m-RNA from a cell are disclosed. Guanidine containing moieties, at high molarity, are use to quickly lyse the cell. They also act to inhibit RNase activity. Without the need for isolation of total RNA, the lysate can then be directly purified from the lysate using oligo dT (or U) by reducing the guanidine concentration via a dilution step.

  • Patent number: 5399668
    Abstract: A cDNA clone (HEV1) encoding hevein was isolated via polymerase chain reaction (PCR) using mixed oligonucleotides corresponding to two regions of hevein as primers and a Hevea brasiliensis latex cDNA library as a template. HEV1 is 1018 nucleotides long and includes an open reading frame of 204 amino acids. The deduced amino acid sequence contains a putative signal sequence of 17 amino acid residues followed by a 187 amino acid polypeptide. The amino-terminal region (43 amino acids) is identical to hevein and shows homology to several chitin-binding proteins and to the amino-termini of wound-induced genes in potato and poplar. The carboxyl-terminal portion of the polypeptide (144 amino acids) is 74-79% homologous to the carboxyl-terminal region of wound-inducible genes of potato. Wounding, as well as application of the plant hormones abscisic acid and ethylene, resulted in accumulation of hevein transcripts in leaves, stems and latex, but not in roots, as shown by using the cDNA as a probe.
