Application

To label carbohydrates, this fluorescent reagent reacts with the reducing termini of oligosaccharids to form a Schiffs base, which can then be stabilized by reducing it with sodium cyanoborohydride.

Analysis of fluorescently labeled oligosaccharides by capillary electrophoresis and eletrospray ionization mass spectroscopy

Wolff, M. W., et al.

Biotechnol. Tech., 13, 797-797 (1999)

An electrophoresis-based assay for glycosyltransferase activity.

K B Lee et al.

Analytical biochemistry, 205(1), 108-114 (1992-08-15)

Polyacrylamide gel electrophoresis (PAGE) and capillary zone electrophoresis (CZE) were used to measure the activity of glycosyltransferases. Acceptor molecules were prepared by reductive amination of the monopotassium 7-amino-1,3-naphthalenedisulfonic acid (AGA) Schiff base with sugars. The resulting sugar conjugates were purified

Outcomes for symmetrical and asymmetrical small for gestational age preterm infants in Canadian tertiary NICUs.

Mingyan Hei et al.

American journal of perinatology, 32(8), 725-732 (2014-12-24)

This study aimed to compare the outcomes for symmetrical (sSGA) versus asymmetrical (aSGA) small for gestational age (SGA) < 32 weeks preterm infants. A total of 12,179 eligible infants admitted to the Canadian tertiary neonatal intensive care units (NICUs) over a 7-year-period

Left Atrial Appendage Closure as an Alternative to Warfarin for Stroke Prevention in Atrial Fibrillation: A Patient-Level Meta-Analysis.

David R Holmes et al.

Journal of the American College of Cardiology, 65(24), 2614-2623 (2015-06-20)

The risk-benefit ratio of left atrial appendage closure (LAAC) versus systemic therapy (warfarin) for prevention of stroke, systemic embolism, and cardiovascular death in nonvalvular atrial fibrillation (NVAF) requires continued evaluation. This study sought to assess composite data regarding left atrial

Molecular Polymorphism and Divergence of Duplicated Genes in Tetraploid African Clawed Frogs (Xenopus).

Ben J Evans et al.

Cytogenetic and genome research, 145(3-4), 243-252 (2015-06-13)

Genome duplication creates redundancy in proteins and their interaction networks, and subsequent smaller-scale gene duplication can further amplify genetic redundancy. Mutations then lead to the loss, maintenance or functional divergence of duplicated genes. Genome duplication occurred many times in African
