  • Publication number: 20230096494
    Abstract: The present invention provides a set of novel isobaric chemical tags, also referred herein as SUGAR (Isobaric Multiplex Reagents for Carbonyl Containing Compound). These labeling tags are compact and easy to synthesize at high yield and purity in just a few steps using commercially available starting materials. The tagging reagents of the present invention comprise: a) a reporter group, having at least one atom that is optionally isotopically labeled; b) a balancing group, also having at least one atom that is optionally isotopically labeled, and c) an aldehyde, ketone, or carboxylic acid reactive group. The multiplex SUGAR tags are able to react with an aldehyde, ketone, or carboxylic acid group of the molecule to be tagged, which offers the capability for labeling and quantitation of glycans, proteins/peptides, and fatty acids.

  • Patent number: 8613845
    Abstract: A complete capillary electrophoresis (CE) system that is capable of providing a continuous flow of effluent at the exit of the flow-through outlet vial is provided. A self-contained capillary electrophoresis system with a flow-through outlet vial for interfacing with mass spectrometry includes a capillary having an upstream inlet end and a downstream terminus end; an electrically conductive hollow needle having an inner wall defining an internal tapered chamber, the internal tapered chamber dimensioned and configured to slidably accept the terminus end of the capillary, the capillary longitudinally inserted into and mounted within the internal tapered chamber to a distance whereby the terminus end of the capillary abuts the inner wall of the needle at the taper; and wherein a micro-reservoir is formed between the terminus end of the capillary and the downstream exit orifice.
