    Abstract: The methods and compositions provided herein relate to the discovery of 13 STR markers, found on the human Y chromosome, having surprisingly high mutation rates when compared with 173 other Y-STR markers known today. The set of RM-Y-STRs may overcome the current dilemma of Y-chromosome analysis in forensic applications due to their extraordinary mutation properties. Embodiments of the invention include methods for allelic determination of rapidly-mutating Y-STR markers, amplification primers for the analysis of rapidly-mutating Y-STR markers, allelic ladders for analysis of rapidly-mutating Y-STR markers, and kits for the analysis of rapidly-mutating Y-STR markers.

    Abstract: Methods and materials are disclosed for use in recovering a biopolymer from a solution. In particular, the invention provides methods for extraction and isolation of nucleic acids from biological materials. The nucleic acids can be separated by forming a stable complex with soluble polysaccharide polymers and magnetic particles, in the presence of detergents and solvent. When the particles are magnetically separated out of the solution, the nucleic acids are separated with them. The nucleic acids can subsequently be released and separated from the particles. The nucleic acid preparation is useful for achieving efficient and accurate results in downstream molecular techniques such as quantification, identification of the source of the nucleic acids, and genotyping.
