摘要:
Compositions and methods are disclosed for substantially dry storage at ambient or elevated temperatures of biological samples such as nucleic acids, proteins and cells in a form from which the samples can be substantially recovered, using a dissolvable or dissociable dry storage matrix comprising a borate composition and a stabilizer as disclosed, such as any of a number of zwitterionic stabilizers.

摘要:
Compositions and methods are disclosed for substantially liquid, gel, suspension, slurry, semisolid and/or colloid storage of biological samples following admixture with the herein disclosed storage composition, permitting substantial recovery of biological activity following storage without refrigeration. In certain embodiments, unfractionated blood or tissue samples may be stored without refrigeration for weeks, months or years in a form that permits recovery of intact DNA, RNA or protein components following the storage period.

摘要:
This invention relates to the collection and handling of biological or chemical specimens. The invention provides a device and a method for collecting and preparing patient samples, such as sputum, to be used in downstream diagnostics tests. The invention reduces the handling and exposure of healthcare workers to the sample by the use of a bag in which hermetic seals are utilized to separate sample aliquots.
摘要:
The present invention provides a method and device for treating and analyzing a biological specimen. The biological specimen is introduced into a processing device and treated thermally, mechanically, chemically or any combination thereof within the processing device to alter at least one constitutive characteristic of the biological specimen and to release or create one or more biological indicators from the biological specimen. The biological specimen is further contacted with a treated polymeric material so that at least a portion of the polymeric material binds to the one or more biological indicators.
