N-Terminal Modification of Gly-His-tagged Proteins with Azidogluconolactone

Publication: Understanding Biosimilars (Primary amino acid sequencing)

The primary amino acid sequence of a biosimilar must be identical to that of its associated innovator. This article describes these regulations and the sequencing techniques that can be used to meet the guidelines.

Publication: Dissecting Structures (Higher Order Structure Determination)

This publication discusses the analytics that should be performed within a biophysical characterization, comparability or biosimilarity study in order to define higher order protein structure.

Publication: Physicochemical Characterization of Insulin

Four well-established techniques: dynamic light scattering (DLS), circular dichroism (CD), nuclear magnetic resonance spectroscopy (NMR), and molecular modelling are combined to provide structural information about insulin.

Publication: O-linked Carbohydrate Characterization

The characterization of O-linked glycosylation requires specific technical expertise and experience. In this paper, our scientists document glycosylation of the C-terminal threonine of the surface glycoprotein of 5 of 5 strains of HIV-1.
