General description

Select-HA is hyaluronic acid (HA) made through enzymatic synthesis where a very high level of size control is possible. Each Select-HA is a narrow-size distribution HA with a specific average molecular weight within a defined range. Polydispersity of Select-HA is as low as 1.02 and averages 1.1 (a value of 1 is for a ‘perfect′ polymer). In contrast, the polydispersity of most other commercial HA is usually greater than 2. Protein content is <0.1% for all Select-HA products.

Analysis Note

The molecular mass of each Select-HA is determined by multi-angle laser light scattering-size exclusion chromatography (MALLS-SEC). Actual result is reported on the lot-specific certificate of analysis. Sold on the basis of mg hyaluronan as determined by carbazole assay.
