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.

Abstract:
A method for preparing a nucleic acid sample for nucleic acid sequencing includes amplifying a nucleic acid target sequence using a primer bound to a first capture substrate; capturing an amplified nucleic acid product by the first capture substrate; generating at least one sequencing ladder from the amplified nucleic acid product using at least one sequencing primer; capturing the at least one sequencing ladder by hybridizing the at least one sequencing ladder to a complementary capture compound on a second capture substrate; and removing the at least one sequencing ladder from the second capture substrate. The first and/or second capture substrate may include a magnetic particle. Other methods, workflows, kits, and computer program media for nucleic acid sample preparation are also disclosed.
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:
Disclosed are compositions, assays, methods, diagnostic methods, kits and diagnostic kits for the specific and differential detection of SARS-CoV-2, including SARS-CoV-2 variants, or other coronaviruses from samples including veterinary samples, clinical samples, food samples, forensic sample, an environmental sample (e.g., soil, dirt, garbage, sewage, air, or water), including food processing and manufacturing surfaces, or a biological sample.
Abstract:
Devices and methods for detecting microbial contaminants, such as bacteria and fungi, in fluids such as drinking water, pharmaceutical solutions and tissue culture media are provided. More particularly, provided are filtration devices for capture and processing of microorganisms from fluids, and improved methods for recovery, lysis and detection of microorganisms based on a combination of physical disruption with small beads and lysis solutions.
