Abstract: The present invention provides a means to identify the alleles present in a DNA-containing sample by providing subsets of loci for amplification by multiplex PCR. The loci include the thirteen CODIS short tandem repeat (STR) loci and amelogenin. The loci within each subset are grouped so that, upon PCR amplification, the amplicons produced within a given subset do not overlap. Differential labeling of subsets makes it possible to further group the subsets into compound multiplexes for co-amplification in a single reaction vessel, and analysis in a single electrophoretic channel.

Abstract: The present invention provides transgenic identification markers (TIMs) and methods of their use for identifying organisms and their progeny. TIMs are synthetically produced, heritable DNA molecules that, when inserted into cells of an individual organism, constitute a distinguishing, synthetic marker system for the organism. Because TIMs are heritable, upon cell division they are passed on to the progeny of the marked organism. TIMs thus provide a means of identifying and distinguishing such marked organisms and their progeny.

Abstract: A method and kit are provided for quantitatively determining the length distributions of the third complementarity determining region (CDR3) of the T cell receptor (TCR) .alpha. and .beta. chains from human lymphocytes in a tissue sample or in the peripheral blood.

Abstract: The present invention is directed to an assay system, a kit, and a process for detecting the length of a polymorphic region of a genetic locus by means of bracketing locus compatible or specific calibrating DNA markers upon electrophoresis in a viscous medium.
