Profile: MicroBioChips is a biotechnology company that deals with protein microarrays (biochips). Biochip technology consists in measuring an interaction between a probe grafted on a solid support, and a target previously labelled or not. The objective behind protein array development is to achieve efficient and sensitive high throughput protein analysis, & carrying out large numbers of determinations in parallel by automated means. Protein arrays make possible the parallel multiplex screening of thousands of interactions and allow to be considered as a tool applicable to a number of applications. PlasmaScan380T antibody microarray is unique in the microarray field by offering the capacity to explore the human plasma proteome by using novel antibody elements with native human protein.
