  • Publication number: 20100106473
    Abstract: The method for modeling a dosing regimen for a medicament includes providing a system having at least two biocompartments. The method determines steady state levels in each of the biocompartments. After that, the method provides for modifying values to calculate an amount of at least one protein in one of the biocompartments to which the protein is being transported. Next, the method calculates and integrates a weighted value of the protein to find a weighted area under the curve. Then, the method calculates and integrates a non-drug value of the protein to find a non-drug area under the curve. Finally, the method evaluates one or more dosing regimens by comparing the weighted area under the curve and the non-drug area under the curve of the protein to determine a net effect of the drug over the time period.

  • Publication number: 20090029865
    Abstract: Novel means and methods for analyzing hybridization data derived from hybridization assays between a target nucleic acid and differently sequenced polynucleotide probes involve selecting probe sets that define reference sequences for sequence signatures and deriving useful data about the nature of the target nucleic acid molecule based on its hybridization to the probes. The methods are useful for determining whether the target contains a nucleic acid or polypeptide sequence signature, whether the target encodes a member of a gene family, or whether the target is derived from one of any number of genes.

  • Publication number: 20080318298
    Abstract: The present invention provides an advance in phage display technology by permitting the uncoupling of the propagation of phages containing inserted sequences encoding heterologous polypeptides from the expression of said polypeptides. The invention provides phage constructs and methods for their use to permit phage coat protein expression, and thus phage propagation, in the absence of display of heterologous polypeptides, which may be expressed as a fusion with said coat protein in a regulated manner.

  • Publication number: 20080176248
    Abstract: The invention provides an affinity filter for the binding of phage-displayed proteins to dissolved target molecules. The phage-displayed proteins are contacted with immobilized target in the presence and absence of dissolved target; the behavior of the phage-displayed proteins as a function of concentration of dissolved target permits approximation of the affinity of the phage-displayed protein for target. The invention also provides a method to screen large numbers of compounds for their ability to compete with a compound known to bind a phage-displayed protein.
