摘要:
Methods for sterilization of ligase-based amplification products, including products of the Ligation Amplification Reaction (LAR), involving treatment of nucleic acid after amplification to render such nucleic acid incapable of serving as a template for further amplification. Both random and site-specific addition of sterilizing compounds, and more specifically, photoactivation compounds, render amplification product subsequently unamplifiable. Self-sterilizing primers are also employed allowing for a homogenous detection of ligase-based amplification product.
摘要:
A quality control assay to verify adequate treatment of blood product following decontamination with furocoumarins and light. The methods involve measuring the inhibition of template-dependent enzymatic synthesis of nucleic acid following the addition of compounds that add covalently to nucleic acid.
摘要:
Methods and compositions are described for treating contaminants in material intended for in vivo use, and in particular blood and blood products for human use. Contaminants in blood cell preparations are inactivated using 8-methoxypsoralen prior to long term storage and transfusion.
摘要:
Apparatus, systems and methods are disclosed for treating a biological fluid with light. A container of biological fluid is introduced into a fluid treatment chamber where it is contacted with light provided by one or more light sources in proximity to the fluid treatment chamber. A drawer for holding containers of biological fluid introduces the containers into the chamber. Containers for holding the biological fluid are marked by the apparatus to indicate the status of the treatment.
摘要:
A device containing a light source, a sample support and a temperature control compartment. The sample support is positioned to support multiple sample vessels for irradiation by the light source. The temperature control compartment maintains the temperature of the sample vessels within a desired range. The light source, sample support and temperature control compartment are all contained within an opaque housing.
摘要:
A device comprising a light source, a sample holder and a temperature control chamber. The sample holder supports the vessels in a fixed relationship relative to the light source. The temperature control chamber surrounds the sample holder and vessels, so that a temperature control fluid may be passed around the sample vessels effectively maintaining the temperature of the sample vessels within a desired temperature range.

摘要:
Hybridization method for discriminating between complementarity and partial complementarity of DNA base sequences. Kinetic covalent entrapment of PCR-amplified target DNA is achieved through the use of crosslinkable probes. A crosslinking site is introduced into the target DNA via the PCR amplification process. Problems with renaturation of target DNA in the PCR process and in the hybridization reaction are minimized.
摘要:
A method for activating photoreactive compounds by supporting sample vessels containing a photoreactive compound at a selected temperature and irradiating the sample vessels while holding the sample vessels at a fixed relationship with the irradiating source so as to uniformly irradiate the compound.
摘要:
Method for treating nucleic acid that is to be amplified such that the nucleic acid is, after amplification, subsequently unamplifiable. Nucleic acid amplification is performed in a reaction containing means in the presence of an isopsoralen. The reaction is thereafter irradiated to render the amplified nucleic acid substantially unamplifiable.
