<p>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).</p>

<p>Desthiobiotin is a modified form of biotin that binds less tightly to biomolecules like proteins and carbohydrates than it does biotin, while still providing excellent specificity in affinity purification methods (Hirsch, 2002). The structure of GD2-oligosaccharide-desthiobiotin (sodium salt) comprises (GalNAcβ1,4Galβ1,4Glc) of its two sialic acids linked α2,3/α2,8 to the central galactose residue (Ledeen, 2009). The desthiobiotin is attached β to position 1 of the reducing glucose moiety. GD2 ganglioside is expressed at a low concentration in the central nervous system, nerves, skin melanocytes and stem cells in healthy adults. On the other hand, GD2 ganglioside is overexpressed in a number of tumors including: neuroblastoma, melanoma, small cell lung carcinoma and brain tumors. Recently, GD2 ganglioside has been found in low concentration on breast cancer stem cells (CSC) that possess: self-renewal properties (division without disrupting the undifferentiated state) and tumor-initiating capabilities. It has been suggested that GD2 ganglioside may be developed as an effective target antigen for CSC immunotherapy (Fleurence, 2017).</p>
