A blood separation device adapted to receive a blood sample having a whole blood portion and a plasma portion is disclosed. The blood separation device includes a housing defining a first chamber, a second chamber, and a separation member disposed therebetween. The blood separation device also includes an actuator, wherein actuation of the actuator draws the blood sample into the first chamber and the separation member is adapted to allow the plasma portion to pass through the separation member to the second chamber. The blood separation device matches the plasma chamber volume, the blood chamber volume, and the applied single pressure source so that the correct trans-membrane pressure and shear rate is obtained.
摘要:
The invention relates to a method, kit and sample collection container for stabilizing nucleic acids in a sample. The invention is based on treating a biological sample, such as body fluids, in particular blood, urine, sputum, or other samples containing biological cells or obtained from a mammalian organism, with one or more salts, comprising at least one salt according to the general Formula I, preferably comprising treating a sample with ammonium formate. The invention further relates to a method for the detection and/or isolation of a nucleic acid from a sample including, or subsequent to, the method for stabilizing said nucleic acids according to the invention, in particular wherein said sample comprises the salts of the invention after having been treated using the method of the invention. The invention also provides a kit for the detection, isolation and/or stabilization of nucleic acids from a biological sample and a collection container configured for the isolation of a biological, preferably blood sample.

A disposable, point-of-care diagnostic cartridge (10) has a base (14) with a reaction chamber (18) and an inlet (26) and a fluidic channel (16) extending therebetween. An apparatus (12) is fixed to the base. The apparatus includes a flexible upper layer (32) having a reservoir (38) containing fluid (22) therein; a flexible lower layer (36), and a rigid substrate (34) sandwiched between the upper and lower layers. The upper layer is fixed to the substrate with a first adhesive having a first bond force. The lower layer has a valve member (24) in fluid communication with a through port (23) in the base and the base inlet The valve member has a closed state (Fig. 3A) to seal off the through port and the inlet from fluid communication and an open state (Fig. 3B) to bring the through port and the inlet into fluid communication. The valve member is moveable from the closed state to the open state under a force less than the first bond force.
摘要:
A sampling and assay kit comprises a cuvette for holding a quantity of a buffer solution and a sample holder including a capillary tube for obtaining a sample. The sample holder includes a body portion which holds the capillary tube. The body portion when inserted in the cuvette, is effective to position the capillary tube within the cuvette at a predetermined position above the end of the cuvette.
摘要:
Bodily fluid sample collection systems, devices, and method are provided. The device may comprise a first portion comprising at least a sample collection channel configured to draw the fluid sample into the sample collection channel via a first type of motive force. The sample collection device may include a second portion comprising a sample container for receiving the bodily fluid sample collected in the sample collection channel, the sample container operably engagable to be in fluid communication with the collection channel, whereupon when fluid communication is established, the container provides a second motive force different from the first motive force to move a majority of the bodily fluid sample from the channel into the container.
摘要:
A syringe for obtaining sub-micron components, including nano-sized components, from a solution includes a barrel having an interior, a needle extending from one end of the barrel, and a plunger received in the interior at an end of the barrel opposite the needle. A filter cartridge is positioned between the needle and the barrel, wherein the filter cartridge maintains at least one membrane having apertures of two distinct size ranges, and wherein operation of the plunger to draw the solution into the barrel allows for retention of sub-micron or nano-sized components of a size between the two distinct size ranges.
