Dextran is a branched glucan composed of linear α(1→6) linked glucose units and α (1→3) link initiated branches. Dextran ranges in size from 10,000 to 150,000 Kd. Dextrans are used in many applications as volume extenders, stabilizers, matrix components, binding platforms, lubricants and physical structure components.
Dextran 40 is used in the development of new improved preservation solutions for organ transplantation. Dextran 40 may be used to determine cell tightness and flux parameters across cell layers. Dextran 40 is used as a colloidal plasma volume extender.

Many important biological questions can be addressed by studying in 3D large volumes of intact, cryo fixed hydrated tissues (⩾10,000μm3) at high resolution (5-20nm). This can be achieved using serial FIB milling and block face surface imaging under cryo conditions.

This work describes the derivatization of dextran using N-(tert-butyloxycarbonyl)-S-(trityl)-L-cysteine in the presence of N,N'-carbonyldiimidazole (CDI) as a coupling agent. Homogeneous reactions in dimethyl sulfoxide allowed for an efficient coupling of the amino acid derivative to the polymer backbone. Derivatization was
