4-Nitrophenyl-β-D-fucopyranoside is a chromogenic substrate for β-D-Fucosidase which yields a yellow solution upon cleavage.

4-Nitrophenyl-β-D-mannopyranoside is a chromogenic β-mannosidase substrate which yields a yellow solution upon cleavage.

4-Nitrophenyl-β-D- xylopyranoside is a chromogenic β-xylosidase substrate, yielding a yellow solution upon cleavage.

Nitrophenyl-β-D-glucopyranoside acts as a chromogenic substrate for β-Glucosidase. When cleaved, Nitrophenyl-β-D-glucopyranoside produces a yellow solution, and its appearance can be measured spectrophotometically.

The study of β-Glucosidase is particularly important as this enzyme is necessary for cell wall degradation and is inherent in some fungi and bacterial pathogens.

The 4xCSL-luciferase plasmid is designed to study the Notch signaling pathway by monitoring the transcriptional activity of CSL (CBF1/Suppressor of Hairless/LAG-1), a key transcription factor in the Notch pathway.

Murine notch homologs (N1-4) undergo presenilin-dependent proteolysis.

The 4xCSL-luciferase plasmid is a synthetic plasmid obtained from a third party and its sequence has been confirmed at Goldbio.

5(6)-Carboxyfluorescein diacetate N-succinimidyl ester or CFSE is a fluorescein dye used to measure cell proliferation for up to 8 generations. It is stable and cell permeable. CFSE becomes fluorescent upon removal of its acetate groups.

5,6-O-Isopropylidene-L-gulono-1,4-lactone is a reagent for chemical synthesis.
