US Patent:

45884919, May 13, 1986

Filed:

Feb 27, 1984

Appl. No.:

6/584138

Inventors:

John H. Kreisher - Ridgefield CT
Hal D. Belle Isle - New Haven CT
Charles A. Nalbantian - New Haven CT

Assignee:

International Biotechnologies, Inc. - New Haven CT

International Classification:

G01N 2728

US Classification:

204299R

Abstract:

This application discloses a horizontal gel slab electrophoresis device comprised of a base containing two buffer chambers having a central divider means positioned below a horizontal self. The horizontal shaft is provided with means for cooling. A movable gel tray is positioned on top of the shelf for containing the gel slab and samples to be analyzed. An electrode is positioned in each buffer chamber adjacent to the central divider means. A valve means is positioned in the central divider means for controlling fluid flow between the buffer chambers. In addition, a port is positioned in each buffer chamber for feeding fluids into each of the buffer chambers. The device is useful in the electrophoresis analysis of samples contained in the gel slab within the movable gel tray.

Appl. No.:

6/690649

Inventors:

John H. Kreisher - Ridgefield CT
Thomas L. McCarthy - Cheshire CT

Assignee:

International Biotechnologies, Inc. - New Haven CT

International Classification:

G01N 2728

US Classification:

204301

Abstract:

A device for the horizontal electroblotting of electrophoretically transferred material comprising a fluid tight container having a floor, a lid and side walls extending between the floor and the lid for defining a chamber, a support assembly located in the chamber for supporting the material to be electroblotted, a first electrode provided below the support assembly and a second electrode provided above the support assembly and a barrier provided in the chamber between the first electrode and the support assembly for diverting bubbles produced by the first electrode so as to prevent the bubbles from accumulating on the support assembly during the electroblotting of the electrophoretically transferred material.

International Classification:

A01N 2500
A01N 2534
A01C 106

US Classification:

424405

Abstract:

A planting system involving a non-damaging stimulus (3) which is placed in the vicinity of a propagule (2) causes a naturally defensive substance (5) to be produced by the propagule. This substance may exist within an encapsulant (1) for a period of time so that the propagule may have enhanced disease control until it develops sufficiently to fend for itself. In one embodiment a large encapsulant surrounds a potato tuber. This encapsulant may include chitin to cause the release of chitinase through intermediate stimulants such as mRNA and activated carbon to absorb or release particular substances. The encapsulant is bound through the use of pentosan which acts with flaked chitin to achieve an outer casing and further protect the propagule both mechanically and chemically.
