    摘要: The invention concerns libraries of chemical compounds, that are useful in medicinal chemistry and related arts, their methods of manufacture and methods of their use. In one embodiment the individual chemical species of the library are synthesized aleatoricly, i.e, by a process involving chance. The chemical species of the library are used while attached to solid phase supports. The library differs from previously disclosed libraries that were intended to be screened while in solid phase in that each individual solid phase support or identifiable portion of a solid phase array displays many species of ligands, collectively termed a "set." The library is constructed so that each set contains a single invariant structure, common to all the species of ligands attached to the particular solid phase support, which is termed a "motif." The invention teaches that libraries of motifs can be employed advantageously compared to known libraries wherein a single species is present on each support.

    摘要: The invention relates to libraries of synthetic test compound attached to separate phase synthesis supports. In particular, the invention relates to libraries of synthetic test compound attached to separate phase synthesis supports that also contain coding molecules that encode the structure of the synthetic test compound. The molecules may be polymers or multiple nonpolymeric molecules. Each of the solid phase synthesis support beads contains a single type of synthetic test compound. The synthetic test compound can have backbone structures with linkages such as amide, urea, carbamate (i.e., urethane), ester, amino, sulfide, disulfide, or carbon--carbon, such as alkane and alkene, or any combination thereof. Examples of subunits suited for the different linkage chemistries are provided. The synthetic test compound can also be molecular scaffolds, such as derivatives of monocyclic of bicyclic carbohydrates, steroids, sugars, heterocyclic structures, polyaromatic structures, or other structures capable of acting as a scaffolding. Examples of suitable molecular scaffolds are provided. The invention also relates to methods of synthesizing such libraries and the use of such libraries to identify and characterize molecules of interest from among the library of synthetic test compound.

    摘要: The present invention relates to methods for determining the amino acid composition, and more preferably the sequence, of a peptide using mass spectrometric techniques. The method is particularly useful for sequencing peptides isolated from natural sources or from libraries of peptides that have been prepared synthetically, and for peptides that are not amenable to Edman degradation sequencing. In one embodiment, the method for determining the amino acid composition or sequence of a peptide comprises determining the difference of the mass of the peptide from the mass of a deuterium-hydrogen exchanged peptide, and from this difference determining the number of exchangeable (labile) hydrogen atoms (protons). Candidate peptides having amino acid compositions or sequences that do not contain the observed number of exchangeable protons are eliminated. In another embodiment, synthesis of a portion of the peptides in a library of peptides is terminated after each coupling step, whereby a set of sequentially truncated fragments of each peptide is formed. Thus the sequence of the peptide can be determined by determining the difference in the molecular weight between each peptide or fragment thereof and the sequentially smaller fragment of the peptide.

    摘要: An apparatus for fragmenting nucleic acid. The apparatus includes a sample reservoir that comprises a fluid having nucleic acids. The apparatus can also include a shear wall that is positioned within the sample reservoir. The shear wall includes a porous core medium that has pores that are sized to permit nucleic acids to flow therethrough. The apparatus also includes first and second chambers that are separated by the shear wall. The first and second chambers are in fluid communication with each other through the porous core medium of the shear wall. Also, the apparatus may include first and second electrodes that are located within the first and second chambers, respectively. The first and second electrodes are configured to generate an electric field that induces a flow of the sample fluid. The nucleic acids move through the shear wall thereby fragmenting the nucleic acids.
