435 6, 435 5, 435 912, 536 231, 536 2433, 536 261, 536 2612

Abstract:

This invention concerns a reagent composition comprising at least two different terminators of a nucleic acid template-dependent, primer extension reaction. This invention also concerns a method for determining the identity of a nucleotide base at a specific position in a nucleic acid of interest. This invention further concerns a method for determining the presence or absence of a particular nucleotide sequence in a sample of nucleic acids. This invention further concerns a method for identifying different alleles in a sample containing nucleic acids. This invention further concerns a method for determining the genotype of an organism at one or more particular genetic loci.

Appl. No.:

09/618178

Assignee:

Beckman Coulter, Inc. - Fullerton CA

International Classification:

G01N 21/25
G01N 21/29

US Classification:

422 8208, 422 67, 435 6

Abstract:

Genotypes of a subject may be determined by analyzing a biological sample. Measurements of the intensity of allele specific signals may be obtained and used to generate reaction values. These reaction values may be compared to probability distributions in order to obtain conditional probabilities of genotypes of interest. The genotype of the subject may be determined based on the measures of these conditional probabilities.

G01N 2100

US Classification:

422 67

Abstract:

A device determines the genotype at selected loci within genetic material obtained from a biological sample. One or more data sets are formed and a set of probability distributions including at least one distribution is established. These distributions associate hypothetical reaction values with corresponding probabilities for each genotype of interest at the same locus or at different loci. The genotype is then determined based on these measures.
