Description

A unique combination of a number of proprietary plasmids digested with appropriate restriction enzymes and PCR products to yield 13 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 250-10,000 base pairs. The 1K and 3K bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 μg a load) for approximating the mass of DNA in comparably intense samples. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

Description

3,5-Dichloro-2-hydroxybenzenesulfonic acid, disodium salt is a reagent used to produce peroxides when combined with 4-aminoantipyrine. It is also used in quantification of hydrogen peroxide through horseradish peroxidase-mediated conversion of itself and 4-aminoantipyrine to a colored product. Under this principle, it is used to determine uric acid in serum as oxidation of uric acid in a uricase-catalyzed reaction yields hydrogen peroxide.

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.)

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).

DMNPE-caged luciferin can be used to measure intracellular functions since it readily crosses cell membranes. Once it is inside the cell, active luciferin can be released by UV light or by the action of endogenous intracellular esterases. DMNPE-caged luciferin makes it easier to follow the changes in gene expression in live cells. It can also be used in combination with DMNPE-caged ATP.

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 the luciferase . This substrate for the firefly luciferase enzyme utilizes ATP and Mg2+ as cofactors and emits a characteristic yellow-green emission in the presence of oxygen, which shifts to red light in vivo at 37°C.

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).

DMNPE-caged luciferin can be used to measure intracellular functions since it readily crosses cell membranes. Once it is inside the cell, active luciferin can be released by UV light or by the action of endogenous intracellular esterases. DMNPE-caged luciferin makes it easier to follow the changes in gene expression in live cells. It can also be used in combination with DMNPE-caged ATP.

DL is a racemic mixture of D-Luciferin and L-Luciferin.
