  • Patent number: 6025149
    Abstract: This invention represents a significant advance in prenatal diagnosis by providing urinary screening to detect fetal aneuploidies. Herein disclosed are methods for prenatally assessing risks of a pregnancy being affected by Down syndrome and other aneuploidies by testing maternal urine samples for levels of .beta.-core-hCG. Levels of maternal urinary .beta.-core-hCG above normal indicate a risk that the pregnancy is affected with Down syndrome, and in general risks of other fetal aneuploidies are indicated by either lower than normal or higher than normal maternal urinary .beta.-core-hCG levels. Assessments can be made based on urinary .beta.-core-hCG levels alone or in conjunction with levels of other urinary and/or serum markers, ultrasound parameters and other factors, such as, maternal age.

  • Patent number: 6017745
    Abstract: Restriction enzymes are used to remove from DNA a complete and undamaged structural gene coding region for the expression of DNA polymerase I (polA) without the gene's natural promoter or with only a significantly damaged portion of the gene's natural promoter. Also by the use of restriction enzymes, a segment from a plasmid cloning vector is excised at a position adjacent to a promoter which is conditionally controllable and may be more powerful than the damaged or removed promoter. The gene for DNA polymerase I is enzymatically cloned into said vector at the position of said removed segment and adjacent to said conditionally controllable promoter. Multicopies of the cloned vector are introduced into a host baterial strain (E. coli). The host strain is then cultured so that the cell colony grows and replicates new generations containing replicated foreign plasmid. During such said replication the activity of said controllable promoter is repressed.

  • Patent number: 6013478
    Abstract: The invention provides methods for the systematic analysis of the structure and function of polypeptides by identifying active domains which influence the activity of the polypeptide with a target substance. Such active domains are determined by substituting selected amino acid segments of the polypeptide with an analogous polypeptide segment from an analog to the polypeptide. The analog has a different activity with the target substance as compared to the parent polypeptide. The activities of the segment-substituted polypeptides are compared to the same activity for the parent polypeptide for the target. A comparison of such activities provides an indication of the location of the active domain in the parent polypeptide. The invention also provides methods for identifying the active amino acid residues within the active domain of the parent polypeptide.

  • Patent number: 6010855
    Abstract: The present invention relates to the isolation of a new gene, des, which encodes a M. tuberculosis protein named DES. The des gene appears to be conserved among different Mycobacteria species. The amino acid sequence of the DES protein contains two sets of motifs that are characteristic of the active sites of enzymes from the class II diiron-oxo protein family. Among this family of proteins, DES shares significant homology with soluble stearoyl-ACP desaturases. DES is a highly antigenic protein, which is recognized by human sera from patients infected with M. tuberculosis and M. leprae but not by sera from tuberculous cattle. Thus, the DES protein provides a useful tool for the serodiagnostic analysis of tuberculosis.
