The A2 N-glycan was found to be the most abundant of all glycoproteins in invertebrates, with a relative abundance of over 50%. It has been shown that the A2 N-glycan can be modified by covalent linking to proteins, differentiating it from other glycans. These modifications may have an effect on the structural stability of the molecule and its susceptibility to environmental degradation. The A2 N-glycan also plays an important role in immunity, as it is immunogenic and can stimulate antibody production. This carbohydrate is uniquely found in humans, which suggests that it may have some importance in human physiology.

Fluorogenic substrate is used for detection of hyaluronidase activity. Urinary hyaluronidase activity is elevated in patients with intermediate and high grade bladder cancer; the expression of hyaluronidase and hyaluronan synthase-1 mRNA in malignant tissue can predict bladder cancer metastasis and disease recurrence (Kramer, 2011). These findings underscore the potential utility of the hyaluronidases to serve as biomarkers for bladder cancer. A novel fluorescent substrate labelled with two dyes: fluorescein as a green donor fluorophore, and rhodamine B as a red acceptor fluorophore, was therefore developed to measure hyaluronidase enzyme kinetics (Zhang, 2008). It was then demonstrated that simultaneous measurements of green and red emission of HA–FRET could be used to measure hyaluronidase presence and activity (Fudala, 2011).
