International Classification:

G01N 33/53
C07H 21/04
C12P 21/06
C12N 5/06
C07K 16/40

US Classification:

Abstract:

The present invention relates to the generation of antibodies that bind to specific modifications of the amino terminus of histone H3 and the carboxy terminus of the H2A and H2B peptides. More particularly, the present invention is directed to the generation of a set of antibodies that recognize various post-translational modifications of histone proteins that function as switches for regulating transcription and mitosis. Compositions comprising these antibodies are used as diagnostic and screening tools.

Abstract:

The present invention is based on the identification of a predominant ligand of CD8+ T cells that are responsible eq for type diabetes. That ligand is islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP). Several CD8+ T cell-binding peptides from IGRP are identified, including the peptide comprising amino acids 206-214 of the IGRP sequence, which has high avidity to the most prevalent T cell receptor of pathogenic CD8+ T cells in autoimmune diabetes. The invention thus provides oligopeptide and polypeptide compositions comprising YLKTN/A/I/L/V)FL, FLWSVFWLI, (T/A)YY/G/T)FLNFM, LR(LV)(F/L)(G/N)IDLL, KWCANPDWI, and SFCKSASIP. Also provided are oligopeptide compositions 8-10 amino acids in length and completely homologous with a mammalian IGRP, where the oligopeptide is capable of binding a human MHC class I molecule. Additionally, various methods of treating a mammal using the above compositions are provided, where the mammal is at risk for or has type 1 diabetes. Also provided are methods of preventing a CD8+ T cell that is cytotoxic to pancreatic islet β-cells from destroying a mammalian β-cell, where the methods also use the above compositions. Further provided are methods for determining whether a mammal is at risk for or has type 1 diabetes, where the methods use the above compositions.

International Classification:

B32B 1504
H01L 2912

US Classification:

428626

Abstract:

A method and apparatus for releasing a workpiece from a substrate including providing a substrate which is transparent to a predetermined wavelength of electromagnetic radiation; forming, on the substrate, a separation layer which degrades in response to the predetermined radiation; providing the workpiece on the separation layer; and directing the predetermined radiation at the separation layer through the transparent substrate so as to degrade the separation layer and to separate the workpiece from the substrate.
