DNA Blood Kit

The Arcis DNA Blood Kit prepares DNA from blood using a novel 3-minute, two-step system. Designed for in vitro diagnostic use, the new kit is sold in a ready-to-use format, and enables users to stabilize and extract nucleic acid from fresh or frozen whole-blood samples without the need for prior sample preparation steps. This kit is also suitable for specimens that have been stored in ethylenediaminetetraacetic acid (EDTA) and heparin-containing solutions. It is nonhazardous, and ships and stores at room temperature for ease of handling. Designed with point-of-care in vitro diagnostics in mind, DNA extracted using the kit is also suitable for use in PCR or other applications. Where access to instrumentation required for traditional extraction methods is not practical, its practicality and ability to be shipped and stored at ambient temperatures has big upsides for users in emerging markets.

Refrigerated Incubators

Heratherm refrigerated incubators provide a consistent temperature environment for incubation applications in the range of 5°C to 70°C, with enhanced accuracy from 15°C to 25°C. The instruments' easy-to-use interface can store up to 10 temperature protocols set by the user, with up to 10 steps in each, and includes an advance timer function, an automatic temperature alarm, and adjustable overtemperature protection. They employ Peltier technology, circumventing the need for a refrigerant by using a thermoelectric element to heat or cool in one module. In addition to using insulation free of chlorofluorocarbons and hydrofluorocarbons—chemicals that are either phased out or are being phased out by the U.S. EPA—they consume very little energy. Heratherm incubators come in two sizes (a 178-L benchtop model and a 381-L floor model) for use in numerous functions, including microbiology/fungi/yeast studies, reagent and antibody storage, and shelf-life testing.

Certified Reference Materials

SPEX CertiPrep was founded in 1954 to provide superior certified reference materials (CRMs) for analytical spectroscopy and chromatography. We have a full line of AA, IC, ICP, ICP/MS, GC, GC/MS, HPLC, and LC/MS standards, in addition to many other products that are used in laboratories around the world. Our product lines include standards for all of the most commonly used environmental testing methods. Our standards are manufactured from the highest-purity materials and rigorously tested to comply with the highest certification levels for CRMs. SPEX CertiPrep's scope of accreditations is the most comprehensive in the industry.

Universal Centrifuges

The UniCen M and UniCen MR centrifuges from Herolab are the ideal choice for small-volume sample use. These microprocessor-controlled models have been especially designed for tubes, bottles, microtiter plates, microliter tubes, and tissue-culture tubes. The maximum capacity of the UniCen is 4 mL x 200 mL. Features such as overspeed detection, imbalance detection, and emergency lid-lock release mechanisms ensure that the models conform to all safety requirements. The stainless-steel chamber, which has an additional inner guard ring, is robust and will provide years of trouble-free service. With the UniCen range, you can chose from 13 angle rotors, 3 swing-out rotors, and 1 microhematocrit rotor. The speed can be set between 500 rpm and 24,000 rpm. There are nine preprogrammed acceleration and deceleration ramps available. An easy-to-read LCD display indicates both current and preset values of speed/g-force, time, and temperature in the case of the UniCen MR, which is refrigerated.

ABI Analyzer Accessories

Gel Company offers accessories for the 3730, 3730XL, 3500, 3130, 3130XL, 3100-AVANT, 377, and 310 genetic analyzers. It also offers a capillary array regeneration service so that you can increase the number of usages from your capillary arrays. If you are using the ABI 3730/3730XL, ABI 3500/3500XL, or ABI 3100/3130XL, simply send us your expired array and we will regenerate it back to its full use for just a fraction of the cost of a brand new array. This service comes with the same warranty as a new array. We will return the array to you clean and dry, suitable for storage, and ready for use. Arrays can be regenerated multiple times. Check our website or catalog for the full range of accessories suitable for Applied Biosystems (ABI) analyzers. There you will also find instructions on how to return arrays for regeneration.

Wnt Signaling Pathway Products

AMS Biotechnology (AMSBIO) offers numerous products for Wnt-signaling research, including recombinant proteins, stable reporter cell lines, polyclonal antibodies, and ELISA assay kits. Wnt proteins are a family of cysteine-rich secreted polypeptides involved in important cell functions including cell-to-cell communication, as well as cell proliferation, migration, polarity, survival, and self-renewal. In particular, Wnt3a signals play an important role in the ability of organoids to expand. Additionally, loss of activation of Wnt expression has been associated with alteration of cell fate, morphogenesis, and mitogenesis, which has considerable relevance in developmental biology and oncology research. Wnt human and mouse recombinant proteins are available in high (85%–90%) and low (75%) purities. The HEK293, HCT-116, or SW480 Wnt stable cell lines all have available matching controls. Polyclonal Wnt antibodies are produced in vivo and are suitable for ELISA, immunohistochemistry, and lateral-flow applications. AMSBIO also offers human and mouse ELISA assay kits.
