    摘要: The present invention includes a method of analyzing one or more molecular components in a mixture of components. In the method, a mixture of molecular components, i.e., an analyte mixture, is separated on a capillary liquid chromatography column. The component-containing eluate from the column is deposited as a series of discrete, defined-volume microdrops, along a region of an adsorbent collection layer. During the chromatographic separation, the column eluate may also be monitored to detect the presence of separated components in the eluate. The one or more components deposited in the collection layer are then analyzed by selected analytical techniques. In related aspect, the invention includes a method of collecting one or more molecular components derived from a mixture of components, a blotter apparatus useful in the above method, and a system for analyzing one or more molecular components in a mixture of components.

    摘要: A solid support and method for immobilization and sequence analysis of polypeptides. In one aspect, the invention is directed to a method for immobilizing a polypeptide on a solid support. In the method, a solid support having surface-attached carboxylic acid groups is reacted with an isoxazolium salt to form an activated support. After the activated support has been washed to remove residual isoxazolium salt and base, the support is dried. The dried support is then contacted with a polypeptide under conditions effective to bind the polypeptide covalently to the support. The immobilized polypeptide can be conveniently sequenced by N- and C-terminal sequencing methods.

    摘要: A solid support having surface-attached carboxylic acid groups is reacted with an isoxazolium salt to form an activated support having enol ester and sulfonate groups. After washing to remove residual isoxazolium salt and base, the activated support is dried. A polypeptide is covalently or non-covalently bound to the support. The resultant immobilized polypeptide can be conveniently sequenced by N- and C-terminal sequencing methods. The support can be a polyvinylidene difluoride membrane or a glass fiber membrane having surface attached carboxylic acid groups, and the enol and sulfonate groups are provided by reacting the support with 2-ethyl-5'-phenylisoxazolium sulfonate. The dry support can be stored for at least about 3 months to achieve a peptide immobilization yield that is substantially the same as the yield obtained in the absence of drying.
