Abstract: A method of assigning parent-of-origin to a haplotype, a sub-haplotype or an allele associated with a haplotype. Chromosome-length haplotypes of a genome are generated and a differential methylation status of at least one imprinted differentially methylated region (iDMR) associated with each one of the autosomal chromosomes is determined. The differential methylation status of the at least one iDMR is used to assign parent-of-origin for each one of the chromosome-length haplotypes.

Abstract: A method for preventing or inhibiting non-specific binding reactions between a detection reagent and an antigen in an immunological assay is described. The method involves using tetrameric antibody complexes that can bind to the antigen and are comprised of two monoclonal antibodies of a first animal species linked to two monoclonal antibodies of a second animal species that can bind the antibodies of the first animal species. Preferably, the antigen is an Fc Receptor and the method reduces the binding of a detection antibody with Fc receptors present on the surface of many cells.

Abstract: The present invention relates to methods for separating cells using immunorosettes. The method involves contacting a sample containing nucleated cells and red blood cells with an antibody composition which allows immunorosettes of the nucleated cells and the red blood cells to form. The antibody composition preferably contains bifunctional antibodies or tetrameric antibody complexes.

Abstract: A method for detecting or quantitating multiple copies of a repeat sequence in a nucleic acid molecule involving treating the nucleic acid molecule with a probe which is a nucleic acid analogue which is capable of hybridizing to the repeat sequence in the nucleic acid molecule and which is labelled with a detectable substance. The nucleic acid molecule is treated with the probe under conditions permitting the probe to hybridize to the repeat sequences in the nucleic acid molecule. Probe hybridized to complementary repeat sequences is identified in the nucleic acid molecule by directly or indirectly detecting the detectable substance. The method is preferably used for quantitating multiple copies of a repeat sequence in a nucleic acid molecule, preferably a telomere or centromere repeat sequence. Novel probes for use in the method of the invention and kits are described.
