  • Publication number: 20190284606
    Abstract: Methods and systems for processing polynucleotides (e.g., DNA) are disclosed. A processing region includes one or more surfaces (e.g., particle surfaces) modified with ligands that regain polynucleotides under a first set of conditions (e.g., temperature and pH) and release the polynucleotides under a second set of conditions (e.g., higher temperature and/or more basic pH). The processing region can be used to, for example, concentrate polynucleotides of a sample and/or separate inhibitors of amplification reactions from the polynucleotides. Microfluidic devices with a processing region are disclosed.

  • Publication number: 20180112252
    Abstract: A microfluidic device includes an input port for inputting a particle-containing liquidic samples into the device, a retention member, and a pressure actuator. The retention member is in communication with the input port and is configured to spatially separate particles of the particle-containing liquidic sample from a first portion of the liquid of the particle containing fluidic sample. The pressure actuator recombines at least some of the separated particles with a subset of the first portion of the liquid separated from the particles. The device can also include a lysing chamber that receives the particles and liquid from the retention member. The lysing chamber thermally lyses the particles to release contents thereof.

  • Publication number: 20130193364
    Abstract: Nucleic acid material can be effectively separated from a fluid under mild conditions by the use of a positively charged polymer which binds the nucleic acid material. Disclosed is a novel positively charged polymer which may be employed in the separation process. This polymer comprises an acidified polyamine, such as polyethyleneimine which has been reacted with a nonacidified polyethyleneimine in a coupling reaction. The acidified polyethyleneimine may be a coarboxylated and/or sulfonated polyethyleneimine.

  • Patent number: 8415467
    Abstract: Nucleic acid material can be effectively separated from a fluid by first contacting the fluid with a positively charged polymer which binds the nucleic acid material. Thereafter, the polymer, having the nucleic acid material bonded thereto, is contacted with a releasing agent which comprises a solution of an alkaline material and a glycol. The solution has a pH of no more than 12 and operates to release the nucleic acid material from the polymer under relatively low temperature conditions, typically no more than 50° C., and in particular instances, no more than 40° C. The glycol material may comprise a monomeric glycol such as ethylene glycol, propylene glycol, or the like, or it may comprise a polymeric glycol such as polyethylene glycol. Also disclosed is a novel positively charged polymer which may be employed in the separation process. This polymer comprises an acidified polyamine, such as polyethyleneimine which has been reacted with a nonacidified polyethyleneimine in a coupling reaction.
