20080273918 | FLUIDIC CONNECTORS AND MICROFLUIDIC SYSTEMS - Fluidic connectors, methods, and devices for performing analyses (e.g., immunoassays) in microfluidic systems are provided. In some embodiments, a fluidic connector having a fluid path is used to connect two independent channels formed in a substrate so as to allow fluid communication between the two independent channels. One or both of the independent channels may be pre-filled with reagents (e.g., antibody solutions, washing buffers and amplification reagents), which can be used to perform the analysis. These reagents may be stored in the channels of the substrate for long periods amounts of time (e.g., 1 year) prior to use. Prior to connection of the fluid connector and the substrate, the fluid path may be filled with a sample (e.g., blood). The sample may be obtained, for example, by pricking a finger of a user until blood is drawn from the finger into the fluid path (e.g., by capillary forces). Upon connection of the fluidic connector and the channels of the substrate, the sample can pass through a reaction area within the first channel of the substrate. This process can allow components of the sample to interact with components disposed in the reaction area. Afterwards, reagents from the second channel can flow to the reaction area via the fluid path, allowing components in the reaction area to be processed (e.g., amplified to produce detectable signal). Components in the reaction area can then be determined using various methods of detection. | 11-06-2008 |
