US Patent:

44734522, Sep 25, 1984

Filed:

Nov 18, 1982

Appl. No.:

6/442580

Inventors:

Charles R. Cantor - New York NY
David C. Schwartz - New York NY

Assignee:

The Trustees of Columbia University in the City of New York - New York NY

International Classification:

G01N 2726
G01N 2728

US Classification:

204180G

Abstract:

Disclosed are an apparatus for and a method of electrophoretically separating particles by electric fields which are transverse to each other, which alternate between respective high and low intensities out of phase with each other at a frequency related to the mass of the particles and which move the particles in an overall direction transverse to the respective directions of the fields. For separating large macromolecules, at least one of the fields preferably has an intensity gradient in a direction transverse to its own. The new arrangement makes it possible to: (1) separate particles (molecules) larger in size than those able to be separated with previously known techniques, (2) carry out separation at higher speed and at better resolution than is possible with previously known techniques, and (3) concurrently separate particles which differ greatly in mass (molecular weight).

Assignee:

The Trustees of Columbia University in the City of New York - New York NY

International Classification:

C12N 1112

US Classification:

435179

Abstract:

Gel inserts comprising a solidified liquid such as agarose suitable for use in an electrophoretic method, lysed cells entrapped within a matrix formed by the solidified liquid and macromolecules such as DNA or intact chromosomes derived from the lysed cells may be advantageously used in electrophoretic separations. The gel inserts are placed directly in a suitable support medium and subjected to one or more electric fields to separate the macromolecules.

US Classification:

435 6

Abstract:

This invention concerns a method for identifying in vitro an animal-infective form of a parasitic protozoan which comprises recovering total mRNA from the protozoan and detecting in the mRNA so recovered the presence of a mRNA transcript encoding a heat shock protein associated with animal-infective parasitic protozoans, which transcript is present only in the animal-infective form of the protozoan, or quantitatively determining in the mRNA so recovered the number of a mRNA transcript encoding a heat shock protein associated with animal-infective parasitic protozoans, which transcript is present in increased number only in the animal-infective form of the parasitic protozoan. This invention also concerns a method for identifying an agent capable of blocking the formation of the animal-infective form of a parasitic protozoan.

US Classification:

435320

Abstract:

DNA which encodes the polypeptide streptavidin has been isolated as a fragment 2 kb in length derived from a restriction endonuclease digestion of the chromosomal DNA of Streptomyces avidinii. The nucleic acid sequence of the gene and the amino acid sequence of the polypeptide have been determined. A fused gene has been prepared which comprises the streptavidin gene fused to a gene encoding the human LDL receptor. Expression of the gene fusion results in a fused streptavidin-human LDL receptor polypeptide. Methods are provided for using the fused gene to produce labeled, chemically modified proteins in vivo and to isolate a protein knowing only the nucleotide sequence of the gene encoding the protein.
