Appl. No.:

11/510493

International Classification:

A61K 31/70
A61K 39/12
A01N 43/04

US Classification:

424204100, 514044000

Abstract:

The invention is directed to compositions comprising polyvalent complexes containing a biocompatible polymer backbone to which is attached a plurality of monomeric anti-microbial peptides and to methods for using such complexes to stabilize anti-microbial peptides for treating or preventing a disease or condition resulting from infection with a microbe. Multivalent derivatives of existing antimicrobial peptides in which several peptides are covalently linked have been investigated. The resulting construct may contain up to 30 or more units, and exhibits a significant enhancement of anti-microbial effect relative to the free peptides: on the order of a ten fold improvement in effectiveness, suggesting that higher multimerization can indeed lead to more effective agents. The invention is also directed to the use of such complexes for delivery of anti-viral peptides, in particular, peptides and peptide fragments obtained from salivary agglutinin protein (gp-340) for use in treating or preventing infection with HIV.

Abstract:

Disclosed are methods, devices and systems for biological and chemical sample processing using microfluidic chips. The disclosed microfluidic chips contain at least two detection zones for interacting with pre-selected RNA sequences, DNA sequences, antibodies, or antigens to determine their presence in the sample. Systems are also described comprising a cassette having at least one port and a sample inlet in fluid communication with a detection zone for interacting with pre-selected RNA sequences, DNA sequences, antibodies, or antigens, or mixtures thereof, if present, in a sample. Methods for concurrent testing of at least two of RNA, DNA, antibody, and antigen in a sample are also described, as are methods for testing for pre-selected pathogens and microfluidic methods.

International Classification:

C12Q 1/68
B01L 7/00

Abstract:

Provided are devices adapted to isolate, amplify, and detect nucleic acids that may be present in a biological sample. The devices can, in some embodiments, isolate, amplify, and detect nucleic acid in a single chamber. In other embodiments, the devices are adapted to isolate and amplify nucleic acids in a reaction chamber, after which the nucleic acids may be communicated to a pervious medium—such as a lateral flow strip—where the user may label and detect the nucleic acids.
