  • Publication number: 20220163549
    Abstract: The present teachings relate to methods, systems, and kits for the preparation, purification and/or analysis of a glycan or glycoconjugate, and specifically to a magnetic bead based sample preparation protocol. In some aspects, the sample preparation protocol can provide for glycoconjugate capture, glycan release, fluorescent derivatization, and glycan purification for subsequent capillary electrophoresis, liquid chromatography, or other glycoanalytical method using magnetic beads containing negatively charged carboxyl groups extending from the surface of the magnetic beads.
    Type: Application

  • Patent number: 11161119
    Abstract: A holder that can be used to stand up a PCR tube on a flat surface or held in a user's hand. The holder has a first elongated portion, a second elongated portion and a third elongated portion. The first elongated portion having a magnet, the second elongated portion having a tube holding means and the third elongate portion acting as a stabilizer to allow the holder to standup in an upright position. The third elongate portion can also be used as a gripping surface to be held between fingers of a hand.

  • Publication number: 20190227086
    Abstract: The present teachings relate to methods, systems, and kits for the preparation, purification and/or analysis of a glycan or glycoconjugate, and specifically to a magnetic bead based sample preparation protocol that can enable full automation and reduced sample preparation time relative to current methods of glycoanalysis. In some aspects, the sample preparation protocol can provide for glycoconjugate capture, glycan release, fluorescent derivatization, and glycan purification for subsequent capillary electrophoresis, liquid chromatography, or other glycoanalytical method without requiring time-consuming sample preparation steps such as centrifugation or vacuum-centrifugation.

  • Publication number: 20170175099
    Abstract: N-glycosylation profiling of glycoprotein biotherapeutics is an essential step in each phase of product development in the biopharmaceutical industry. For example, during clone selection hundreds of clones should be analyzed quickly from limited amounts of samples. On the other hand, identification of disease related glycosylation alterations can serve as early indicators for various pathological conditions in the biomedical field. We describe an improved packed bed column PNGase F functionalized column reactor. The reactor may be packed into a pipette tip column. In some embodiments, a second column or mixed stationary phase may be packed into the column to capture and purify the cleaved glycan prior to analysis. Complete N-glycan removal can be obtained in 10 minutes from all major N-linked glycoprotein types. The approach can be readily applied to automated sample preparation systems, such as liquid handling robots.
