摘要:
Methods, apparatus, compositions, systems, and articles of manufacture useful in connection with performing offsite mass spectrometric (MS) analysis of samples are disclosed. In embodiments, library samples are arrayed on MS substrates in a blinded fashion and stability-packaged for transport to an off-site location where the MS substrate is de-packaged and MS analysis is performed, enabling off-site MS analysis without requiring transport of the sample library and without compromising the confidentiality of the library contents. Also disclosed are embodiments relating to substrates for desorbing and ionizing analytes, including kits and methods of use thereof.

摘要:
Disclosed are methods for direct characterization of microdomains and/or three-dimensional microstructure arrays bearing high densities of reactive sites using Matrix Assisted Laser Desorption Ionization Time of Flight Mass Spectrometery (MALDI-MS) and other analytical techniques. The high site density of the arrays can provide sufficient sample of each array element and/or materials bound to each element to obtain directly using common analytical techniques such as MALDI-MS. Spatially directed synthesis of heteropolymers is done through the use of pliotolabile, electrically labile, and chemically labile protecting group(s).
摘要:
A microarray has a substrate and a plurality of three-dimensional microstructures formed on the substrate. Each of the three-dimensional microstructures is made with polymer material and has a plurality of reactive sites formed on its surface and interior pores. The polymer material is polymer gel or other porous polymer. The combination of three-dimensional microstructure and porous polymer material increases the surface area of the microstructure and density of the reactive sites on the surface of the microstructures. The higher density of reactive sites increases the luminescence, visibility or instrument detectability of the interaction between analytes and reactive microstructure sites on the microarray. A plurality of chemical groups are respectively attached to the reactive sites. The chemical groups each include at least one monomer. The chemical groups may have different chemical structures. A plurality of microchannels can be formed around the microstructures for isolation.
