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.

Agarose LE (Molecular Biology Grade)

A-201-500 500 g $ 415.00
A-201-1000 1 kg $ 705.00

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

Ampicillin sodium is a member of the extended-spectrum β-lactam family and similar in structure to penicillin. It is used in the selection of antibiotic cell hybrids and has a high rate of action against many gram-negative bacterial strains. Ampicillin sodium targets non-ESBL (Extended Spectrum β-lactamase) bacteria including Staphylococcus and Streptococcus species and medically important enteric pathogens such as Shigella and Salmonella. It has been found to be effective against certain β-lactam sensitive VRE or vancomycin resistant Enterococcus species. Resistance to ampicillin is routinely utilized as a selectable marker to confirm successful cell transformation. Ampicillin Sodium is freely soluble in water.

Description

Carbenicillin is a member of the penicillin β-lactam antibiotics. However, unlike most β-lactams, carbenicillin disodium is limited to primarily gram-negative bacteria including Pseudomonas aeruginosa and common enteric species. It can be used in selection protocols and is often preferred over ampicillin due to its increased stability. This allows for less contamination of unwanted bacterial colonies. In addition, carbenicillin has been used to regulate bacterial growth in plants, yielding low regeneration frequencies. It can be used in genetic transformation applications to select for AmpR transformed cells.

Description

Luciferin is a common bioluminescent reporter used for in vivo imaging of the expression of luciferase. This water soluble 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.

Description

Dithiothreitol (DTT) is the common name of the more popular of the two Cleland’s Reagents (the other being Dithioerythritol or DTE). DTT is a powerful reducing agent that forms a stable six-membered ring with an internal disulfide bond which is resistant to oxidation. DTT is often used for the following: reducing the disulfide bridge of the cross-linker N,N′-bis(acryloyl) cystamine to break apart the matrix of a polyacrylamide gel, the reduction of disulfide bonds in proteins, the prevention of those bonds from forming between cysteine residues and lastly, DTT is often used to reduce thiolated DNA in order to minimize dimerization.

DTT is a nearly 7-fold stronger reduction agent than βME (β-mercaptoethanol) and has a less offensive odor and is less toxic.

Description

G-418 sulfate, also known as geneticin, is an aminoglycoside antibiotic similar in structure to gentamicin B1. It is commonly used in plant and mammalian cell culture as a selectable marker. It can be used to select for cells transformed with an iNOS promoter construct or neomycin resistance gene.

G-418 functions by causing a chain of nonsense mutations during translation, ultimately resulting in inhibition of polypeptide synthesis and protein elongation. Resistance to G-418 is conferred through the nptll gene in plant cells and the neo gene in mammalian cells, which encode aminoglycoside 3'-phosphotransferase. For gene selection applications, a kill curve can be made to determine the minimum effective G418 concentration to kill non-resistant cells. G418 disulfate is freely soluble in water.

Description

HEPES is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, piperazinic buffer that is useful for a pH range of 6.8 – 8.2. HEPES lacks the ability to form a significant complex with most metal ions and is recommended for use as a non-coordinating buffer in solutions with metal ions.

Description

Hygromycin B is an aminoglycoside antibiotic isolated from Streptomyces hygroscopicus. It is commonly used to study protein synthesis. Aside from its efficacy against bacteria, fungi, and higher eukaryotic cells, hygromycin B is also an antiviral agent inhibiting translation upon selectively entering cells made permeable due to viral infection. It works as a standard selection antibiotic in gene experiments, especially for selection of hygromycin resistance gene transformed cells.

IPTG is an analog of galactose that is non-metabolizable and inactivates the lac repressor to induce synthesis of β-galactosidase in E. coli. The expression of cloned genes under the control of the lac operon is induced by IPTG. It is also a substrate for thigalactoside transacetylase and has been reported to induce penicillinase in bacteria.
