摘要:
A method in which a temperature gradient is generated across a “gradient” block, and an apparatus comprising a block across which a temperature gradient can be generated. By setting up such a gradient, multiple reaction mixtures held in wells on the gradient block can be simultaneously run at temperatures which differ only slightly, thereby permitting an optimum temperature for the reaction to be quickly identified. In a preferred embodiment the gradient block is integrated into a thermal cycler used for nucleic acid amplification reactions.

A system for transmission of data between a first device operated by a first user and a second device operated by a second user includes a database that receives a first set of data input by the first user and a second set of data input by the second user. In one embodiment, the second user can access at least a first portion of the first set of data from the database only after the second user authorizes the first user to access at least a first portion of the second set of data from the database. In another embodiment, the first set of data includes an immediate mode of access and/or one or more future modes of access of the first user which correlate to one or more specific time periods during which the future mode of access will become the immediate mode of access. Additionally, the first set of data can include a time-dependent schedule of the future mode of access of the first user. The second device can be a mobile phone having a memory that is automatically updated by the database with data input by the first user. Moreover, the first user can specify a hierarchical privacy level for one or more data fields, and a correlative hierarchical clearance level to the second user. The clearance level is compared with the first privacy level to determine whether the second user has access to any of the data fields.

The present invention provides methods and compositions for specifically identifying a fetal cell. An initial screening of approximately 400 candidate genes by digital PCR in different fetal and adult tissues identified a subset of 24 gene markers specific for fetal nucleated RBC and trophoblasts. The specific expression of those genes was further evaluated and verified in more defined tissues and isolated cells through quantitative RT-PCR using custom Taqman probes specific for each gene. A subset of fetal cell specific markers (FCM) was tested and validated by RNA fluorescent in situ hybridization (FISH) in blood samples from non-pregnant women, and pre-termination and post-termination pregnant women. Applications of these gene markers include, but are not limited to, distinguishing a fetal cell from a maternal cell for fetal cell identification and genetic diagnosis, identifying circulating fetal cell types in maternal blood, purifying or enriching one or more fetal cells, and enumerating one or more fetal cells during fetal cell enrichment.
