Description

Hyaluronic Acid is labeled with biotin through an amide bond. Purity: >95% lyophilized powder. Standard Degree of substitution (DoS): 1 mol % substitution. Other biotin labeling ratio such as 5% can be ordered through custom synthesis. Synonyms: HA, hyaluronate, hyaluronan.

Properties

Name and Source: Hyaluronic acid (HA, Hyaluronan, Hyaluronate) is an anionic, non-sulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. CAS# 9004-61-9. Our HA products are produced via microbial fermentation. See Documents section for details.

Appearance: White lyophilized powder.

Solubility: Soluble in water and the solubility data varies with MW. Higher MW results in lowered solubility. Typically solubility ranges 5-50 mg/mL, that is, 0.5%-5%. Buffered solution at pH >6 enhances solubility due to deprotonation of carboxylic acid groups and formation of carboxylate salts. HA derivatives with hydrophobic groups will lower the solubility in water, and adding alcohol or DMSO to an alcohol-water or DMSO-water mixture can dramatically improve the solubility up to 200 mg/mL (20%).

Degree of Substitution (DoS): The standard DoS is 1% by default. Product variants with special DoS other than 1% is indicated in the product name and catalog number. For example, HA-635-2% means that the DoS is 2% for this particular product.

The substitution or labeling ratio is the percentage of HA disaccharide monomers that are functionalized with the functional groups. You may calculate the number of functional groups in each HA polymer chain by 1) dividing the MW of HA by the MW of one disaccharide monomer to derive the number of disaccharide monomers in HA; 2) then multiple the number of disaccharide monomers by the labeling ratio or DoS to get the number of functional groups in each HA polymer. See Documents section for details.
