This product can be detected by spectrophotometry at an excitation wavelength of 395 nm and emission wavelength of 510 nm. The Ostazin Brilliant Red H-3B Galactomannan substrate is useful in detecting Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Group A streptococci, Group B streptococci, Group D streptococci, Group G streptococci, and Group C streptococci.</p>

<p>5-Bromo-6-chloro-3-indolyl α-D-glucopyranoside is a chromogenic substrate that yields a magenta-colored product after cleavage. The chromophore 5-bromo-6-chloro-indoxyl is released, generating the observable color. It is used in Pompe disease diagnostics, a glycogen storage disorder, that measures the deffiency of alpha-glucosidase (GAA) that could lead to the accumulation of glycogen in lysosomes.</p>

<p>4-Methylumbelliferyl 2-acetamido-2-deoxy-beta-D-glucopyranoside-6-sulfate potassium salt is a fluorogenic substrate for beta-N-acetylglucosaminidase. After enzymatic cleaveage, free 4-methylumbelliferone (also known as hymecromone) is released, exhibiting blue fluorescence upon excitation with UV light. The strongest fluorescence of 4-methylumbelliferone requires deprotonation of the hydroxyl group (thus requires alkaline pH), with a maximal fluorescence intensity obtained with excitation at 350 to 370 nm and emission at 440 to 470 nm. The use of 4-methylumbelliferyl 2-acetamido-2-deoxy-beta-D-glucopyranoside-6-sulfate potassium saltas a substrate for measuring the beta-N-acetylglucosaminidase activity is used for diagnosis of Mucopolysaccharidosis IIIB (MPS IIIB) (a rare lysosomal storage disorder) and Sanfilippo B syndrome screening.</p>
