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.

A-201-1000 1 kg $ 562.00   $ 478.00

Description

Agarose LE (Low Electroendosmosis) is Molecular Biology Grade and is specifically designed for the superior separation of nucleic acids, with maximally crisp band resolution, and is also ideal for cloning and cloning related experiments.

GoldBio Agarose LE is refined in an advanced process that excludes the use of organic solvents. The result is a cleaner end-product with significantly reduced environmental impact. The agarose can be used for analyses of nucleic acids from 50 bp to 25 kbp, protein electrophoresis and various blotting protocols.

The low EEO of the agarose promotes increased electrophoretic mobility, yielding improved resolution and shorter run times. This also allows macromolecules and larger particles (subcellular fragments, viruses, etc.) to migrate more freely through the gel matrix. The consistently low EEO reduces band distortion (caused by counterflow) that can result from the presence of excessive sulfate-rich negative ions.

Agarose is a natural product that forms an inert matrix used in electrophoresis, chromatography and other molecular biology and biochemistry techniques. Likewise, it is neutral and easily derivatizable, so it is easy to bind to its structure proteins like enzymes, antigens or antibodies. Toxicity absence makes working with agarose very convenient.

Description

The BLUEstain™ 2 Protein ladder is a three-color protein standard with 13 prestained proteins, covering a wide range molecular weights from 3.5 to 245 kDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-glycine buffer). 


The BLUEstain™ 2 Protein ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute or add reducing agent before loading.

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.)

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.
