ABSTRACT
The microarrays have revolutionised biomedical experimentation and diagnostics, enabling ordered high throughput analysis. During the past decade, classic solid phase substrates, such as microlitre plates, membrane filters and microscopic slides, were turn into high-density, chip-like structure. The concept of the arrayed library was central to this development which now extends from DNA to protein. The availability of such protein microarrays would facilitate the simultaneous analysis of thousands of interactions within a single experiment. They can be utilized for massively parallel testing of protein function or recognized their target polypeptide in complex biological solution. This article will focus on the current strategies used to generate protein microarray and their applications in biological research, medicine and diagnostics.
