Filed:

Nov 30, 2001

Appl. No.:

09/998481

Inventors:

Francis Barany - New York NY, US
Weiguo Cao - Central SC, US

Jing Lu - Central SC, US

Assignee:

Cornell Research Foundation, Inc. - Ithaca NY

International Classification:

C12Q 1/68
C12P 19/34

US Classification:

435 6, 435 911, 435 912, 435 9152, 204450

Abstract:

The present invention is a method for detecting DNA sequence differences including single nucleotide mutations or polymorphisms, one or more nucleotide insertions, and one or more nucleotide deletions. Labeled heteroduplex PCR fragments containing base mismatches are prepared. Endonuclease cleaves the heteroduplex PCR fragments both at the position containing the variation (one or more mismatched bases) and to a lesser extent, at non-variant (perfectly matched) positions. Ligation of the cleavage products with a DNA ligase corrects non-variant cleavages and thus substantially reduces background. This is then followed by a detection step in which the reaction products are detected, and the position of the sequence variations are determined.

International Classification:

B01D 46/10

US Classification:

96222, 55501, 55528, 55500

Abstract:

The Economic Air Filter for Household according to the present disclosure includes two Claims: () A re-usable metal net AIR FILTER CASE/FOLDER/SANDWICH for holding the AIR FILTER SHEET; () The TWO WAY AIR FILTER SHEET series, and AIR FILTERING FOLD SHEET.The re-usable metal net Air Filter Case/Folder/Sandwich (Claim I) designs are a creation to reduce the air filters waste amount for Green Environment Campaign. The TWO WAY AIR FILTER SHEET series (Claim II) is another creative idea to form a complete set of the Economic Air Filter for Household. The AIR FILTERING FOLD SHEET is designed with dust pocket for household who have pets or newly painted rooms. The basic Two Way Air Filter Sheet is disposable as regular household garbage, and effectively filtering out the Debris & Lint and Household Dust to protect Heating and A/C system. With filter elements in inner layer in series that can target different problems. Such as, Pollen, Dust Mite Debris, Mold Spores, Pet Dander, Smoke, Smog, Bacteria, Particles that can carry viruses and odor.If any Two Way Air Filter Sheet product in the series requires special dispose procedures, we will clearly Label it.
