Patents by Inventor Graham Stuart Plastow

Graham Stuart Plastow has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods
    Patent number: 7371521
    Abstract: Methods for determining the KIT genotype of pigs are provided. These methods are useful in determining coat colour genotype, breed determination and for screening pigs to determine those likely to produce larger litters, and/or those less likely to produce large litters. Kits for use in such methods are also provided.
    Type: Grant
    Filed: April 24, 2002
    Date of Patent: May 13, 2008
    Assignee: Pig Improvement Company UK, Limited
    Inventors: Leif Andersson, Elisabetta Giuffra, Graham Stuart Plastow, Olwen Irene Southwood
  • Methods for analyzing animal products
    Patent number: 7285385
    Abstract: The present invention provides methods for analysing animal products. In particular methods for differentiating animal products on the basis of breed origin or validating an animal product are provided.

  • DNA markers for litter size
    Patent number: 6410227
    Abstract: Methods for screening pigs to determine which are more likely to produce larger litters and/or are less likely to produce larger litters are provided, based on identification of OPN alleles present in a sample of pig genomic DNA. Kits for use in such methods are also provided.

  • Methods for determining the coat color genotype of a pig
    Patent number: 6183955
    Abstract: Coat color is important to the pig breeding industry for a number of reasons. It is therefore desirable to develop populations of pigs which will breed true for coat color. However, establishing such populations would be time-consuming and costly using traditional test mating programs. It is therefore desirable to determine the coat color genotype of individual pigs. The inventors have shown that the KIT gene in pigs is involved with coat color determination. Specifically, the inventors have discovered that the difference between the I, IP, and i alleles of the coat color determining gene is duplication of at least part of the KIT gene in the I and IP alleles. Further, the inventors have discovered that the difference between the I and IP alleles is that, although both I and IP have a duplication in the KIT gene, only I and not IP exhibits a deletion in one of the duplicated regions.
