General description

The Oligo-HA products are small-molecular weight hyaluronic acid prepared with streptococcal or recombinant bacterial HA via testicular HAase digestion and purified by gel filtration. The hyaluronan disaccharide subunit is glucuronic acid-β-D-(1→3)-N-acetyl-D-glucosamine-β-D-(1→4) (GlcAβ3GlcNAcβ4), and each Oligo-HA is an defined oligomer of the subunit.

Application

Oligo-HA4 has been used in a study to assess microbial production and applications of chiral hydroxyalkanoates. It has also been used in a study to investigate in situ preparation and continuous fiber spinning of poly(p-phenylene benzobisoxazole) composites.

Analysis Note

May contain trace amounts of other oligomers. Sold on the basis of carbohydrate as determined by carbazole assay.

Other Notes

Oligo-HA4 is a monodisperse tetrasaccharide comprised of two hyaluronan disaccharide subunits (Nonreducing-GlcAβ3GlcNAcβ4GlcAβ3GlcNAcβ4-reducing end).
