چکیده

Automated oligosaccharide assembly requires suitable linkers to connect the first monosaccharide to a solid support. A new hydrogenolysis-labile linker that is stable under both acidic and basic conditions was designed, synthesized and coupled to different resins. Glycosylation and cleavage efficiencies on these functionalized solid supports were investigated, and restrictions for the choice of solid support for oligosaccharide synthesis were found.

Applicability of imaging time-of flight secondary ion MS to the characterization of solid-phase synthesized combinatorial libraries.

We employ imaging time-of-flight secondary ion mass spectrometry to perform high-throughput analysis of solid-phase synthesized combinatorial libraries by acquiring mass spectra from arrays of polymer resin particles. To generalize this procedure to various types of resins and their associated chemical linkers, it is necessary to understand the dynamics associated with the analyte molecules dur...

Label-free optical detection of peptide synthesis on a porous silicon scaffold/sensor.

Mesoporous porous silicon (PSi) microcavity sensors are used to conduct conventional solid-phase peptide synthesis. The sensor optical response provides a convenient means to monitor the synthesis reaction in a nondestructive manner. Measurements indicate that peptide synthesis occurs only when the PSi sensor/scaffold is amine-terminated using, for example, the amino silane or deprotected acid-...

A comparative study of supports for the synthesis of oligonucleotides without using ammonia

A comparative study of the cleavage efficiency of succinyl, phthaloyl, oxalyl, 2-(2-nitrophenyl)ethyl, 9-fluorenylmethyl, and 2nitrophenyl supports in 0.5M DBU solutions is described. A decrease in cleavage efficiency is observed when small oligonucleotides containing thymidine are linked to the supports. In these conditions oxalyl supports gave the best yields followed by 2-(2-nitrophenyl)ethy...

Acylsulfonamide safety-catch linker: promise and limitations for solid–phase oligosaccharide synthesis

Safety-catch linkers are useful for solid-phase oligosaccharide synthesis as they are orthogonal to many common protective groups. A new acylsulfonamide safety-catch linker was designed, synthesized and employed during glycosylations using an automated carbohydrate synthesizer. The analysis of the cleavage products revealed shortcomings for oligosaccharide synthesis.

Histone H1 Sub-types in Mouse: Interplay Between Phosphorylation and O-Glycosylation

Linker histone H1 belongs to the family of proteins that are involved in organizing eukaryotic DNA into a compact structure. Many types of linker histone H1 are found in mammals; and the subtypes are cell specific and their amount in different types of cells varies according to the cell functions. Post-translational modifications occur on different amino acids in each subtype of linker histone ...
