![]() Macherey-Nagel 150 Safety cabinet. This biological unit is used to transfer animals. It has an ergonomic design and provides protection for personnel, animals, and the environment. This Class II, Type A/B3 cabinet provides safety and project flexibility. Online shopping. This site offers a wide selection of liquid chromatography supplies, including HPLC columns, guards, and accessories in various phases, lengths, and inside diameters. The online store is located at Keystones home site, www.keystonescientific.com. Compact benchtop unit. The IC20 operates as a dry bath, water bath, incubator, refrigerator, or freezer at your workstation. The unit can freeze, chill, or heat samples from 10 to 100 °C in assay plates, centrifuge tubes of all sizes, vials, and test tubes. It has a digital display and control of temperature to 1 °C. The unit also has a countdown timer in days, hours, minutes, and seconds to 30 days. Toxicology screening. This system can be used to analyze biological fluids such as blood, urine, and bile, as well as tissue extracts and stomach contents. It can detect more than 600 drugs and their associated metabolites. By using drug markers to produce an almost linear retention index scale, the system employs a chromatographic technique for toxicological drug screening. Specimen observation. These differential interference contrast (DIC) systems are designed to be used with BX2 series microscopes. They allow optimum imaging of all specimens, including thick and thin cells at high and low magnification. DIC systems are used with polarizing filters and prisms. Personal synthesizer. This versatile tabletop organic instrument is ideal for process
Biotechnology glossary. The site www.biotechterms.org is a fully searchable version of Technomics Glossary of Biotechnology Terms, 2nd ed., by Kimball R. Nill. The glossary is designed for anyone with an interest in biotechnology, including executives who deal with the biotechnology industryparticularly those who may not be formally trained in biotechnology. Clear, concise definitions are provided for quick reference. A unique feature of the online glossary is a reference chain that allows visitors, after finding a terms definition, to immediately identify and find other definitions of related terms.
DNA polymerase. Bio-X-Act handles various problems encountered when trying to amplify DNA for which standard polymerase is not sufficient. The system provides primer extension over long regions by reducing premature strand termination and template degradation. It also provides high yield and specificity, even with dirty DNA or difficult templates. In addition to 5¢3¢ DNA polymerase activity, Bio-X-Act possesses 3¢5¢ proofreading activity, which prevents misincorporations during primer extension. This combination of properties allows Bio-X-Act to give sevenfold higher fidelity than standard polymerase.
Mass plate storage. This tool stores large numbers of microplates for targeted and ultrahigh-throughput screening. The automated plate storage and retrieval systemMega-Storpresents compound daughter plates to a robotic platform, stacker system, or cherry picker and can dramatically improve laboratory work flow. The unit is a freestanding vertical cylinder with dual carousels. Mega-Stor operates as a storage unit at temperatures from 25 C (ambient) to 20 C. The dual carousels consist of 25 columns of microplate holding shelves, which can be configured to hold deep-well plates, half-height plates, or standard microplates. The user can change the configuration to hold up to 1675 standard microplates, 1080 half-height plates, or 850 deep-well plates. Glovebox. The 870 Closed Loop Containment Isolator is completely automated and has negative pressure. If the internal negative pressure rises above 0.55 in. H2O, the programmable logic controller opens the atmosphere supply valve. Incoming gas is automatically filtered through dual HEPA filters. When the internal atmosphere reaches the point set by the user, the automatic valve closes. The unit also features a manual ball valve for connection to an exhaust/filter system. Antibodies and antigens. These compounds are useful in various neuroscience applications, such as immunohistochemistry, immunoassays, immunofluorescence, immunocytochemistry, and Western blot. Monoclonal antibodies have been developed specifically for astrocytes, dopamine, G0 protein, MAP-2, phodopsin, S-100, synaptophysin, syntaxin, and tau. Assay. This protein conjugate screening column allows drug protein conjugate isolation in about 20 s for fast combinatorial library screening. It requires less than 10 nmole of protein for detection and is recommended whenever sample protein is limited. With an exclusion limit of 600 Da, small solutes can be quickly separated by size from the s conjugate without affecting even weak binding constants. Columns can be coupled directly to reverse-phase columns for LC/MS detection to fully automate the technique. |
