Adenine 9-β-D-arabinofuranoside (Vidarabine)

Catalog ID Size Pricing
A-145-100 100 mg $ 57.00
A-145-500 500 mg $ 168.00

Description

Adenine 9-beta-D-arabinofuranoside (ara-A) is a synthetically produced purine nucleoside that is used in cell signaling research. It has commonly been used in anti-viral research with hepadnaviridae and herpes simplex viruses. The nucleoside ara-A interferes with viral DNA synthesis, but only in its active phosphorylated form. Active ara-ATP inhibits synthesis by incorporating into viral DNA and preventing phosphodiester bridge formation.

The compound ara-A is a precursor of adenine 9-beta-D-arabinofuranoside 5’monophosphate (ara-AMP). In vivo rat experiments of ara-AMP have shown a higher solubility and affinity for some proteins, both of which facilitate ara-AMP movement. Isolated human hepatocytes have also been shown to specifically endocytose the albumin/ara-AMP conjugate.

Description

Bluo-Gal is used as an alternative to X-Gal, and produces a darker blue color. Bluo-Gal is hydrolyzed by β-galactosidase to produce a blue precipitate. This precipitate is insoluble in alcohol and xylenes, thus making it suitable for immunoblotting and immunocytochemical assays. Bacterial colonies containing active β-galactosidase produce blue colonies when grown on plates containing Bluo-Gal.

Description

Tested and Certified for in vivo imaging (See "Luciferin FAQ" in additional information)

Luciferin is a common bioluminescent reporter used for in vivo imaging of the expression of luciferase. This substrate for the firefly luciferase enzyme utilizes ATP and Mg2+ as cofactors to emit a characteristic yellow-green emission in the presence of oxygen, which shifts to red light in vivo at 37°C. Through the utilization of ATP, the reaction can be further used to indicate the presence of energy or life in order to function as a life-death stain.

Luciferin is a common reagent used throughout the biotechnology field and specifically for in vivo imaging. Luciferase labeled tumor cells, stem cells or infectious diseases are often inoculated into research animals such as rats or mice for investigation. The injection of luciferin allows for the real-time, noninvasive monitoring of disease progression and/or drug efficacy in these model systems through Bioluminescence Imaging (BLI).

Luciferin is also commonly used for in vitro research, including luciferase and ATP assays, gene reporter assays, high throughput sequencing and various contamination assays.

Firefly Luciferin is identical to Beetle Luciferin. (See "Additional Information" for structures.)
