Filed:

Aug 3, 2000

Appl. No.:

09/601664

Inventors:

Li Lin - Wallingford PA

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

G01N 346

US Classification:

73 81, 73 7

Abstract:

This invention concerns a test apparatus and procedure used for quantitative and qualitative characterization of scratch and mar behavior of films or coatings, more particularly automotive coatings. The apparatus includes a micro-indentor that penetrates and scratches the coating to be characterized together with interrelated components for measuring the force applied, the length and depth of the indentor penetration, the geometry of the disturbed coating surface as well as a system for measuring, analyzing and comparing test results.

International Classification:

C07H 21/04
C12Q 1/68

US Classification:

536 235, 435 61

Abstract:

Described herein are nucleic acid modules for cloning, expression and tagging of eukaryotic membrane proteins. The nucleic acid modules include a receptor for advanced glycation end products (RAGE) signal sequence, a nucleic acid sequence encoding a tag and a multiple cloning sequence (MCS). Any membrane protein of interest can be cloned into the MCS for expression in cells. The nucleic acid modules can encode any type of tag, such as an epitope tag or affinity tag. The nucleic acid modules disclosed herein can be used to express any type of membrane protein and are particularly suited to the expression and tagging of Type I and Type III membrane proteins.

International Classification:

A61K 31/711
C07K 14/00
C12M 1/34

C12N 1/00

US Classification:

514 44, 530350, 435243, 4352871

Abstract:

A series of p105-based NF-κB super repressors, designated p-105(sr), have been designed. The p105(sr), no longer generates p50 and undergoes signal-induced degradation, effectively inhibiting all NF-κB activities. Additionally, p105(sr) significantly enhances tumor necrosis factor alpha (TNF-α)-mediated killing of MT1/2 skin papilloma cells when p50 homodimer activity is elevated. p105(sr) is an effective NF-κB super repressor with a broader range than other currently available IkBα super repressors. The novel repressor can be used in cells where a noncanical NF-κB activity is dominant or multiple NF-κB activities are activated.
