描述: SymmetryShield™ columns feature Waters' patented embedded polar group technology that shields the silica's residual silanols from highly basic analytes at improves overall peak shape. Additionally, by placing the embedded polar group close to the silica surface, the activity of the surface silanols is further reduced. This imparts selectivity and retention that is different compared to the Symmetry® C18 ligand.

Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser Ecto-5-prime-nucleotidase (5-prime-ribonucleotide phosphohydrolase) catalyzes the conversion at neutral pH of purine 5-prime mononucleotides to nucleosides, the preferred substrate being AMP. The enzyme consists of a dimer of 2 identical 70 kD subunits bound externally to the plasma membrane by a glycosyl phosphatidyl inositol linkage. The enzyme is used as a marker of lymphocyte differentiation. Consequently, a deficiency of NT5E occurs in a variety of immunodeficiency diseases. Other forms of 5-prime nucleotidase exist in the cytoplasm and lysosomes and can be distinguished from ecto-NT5 by their substrate affinities, requirement for divalent magnesium ion, activation by ATP, and inhibition by inorganic phosphate. It is not known whether the different enzymes are coded by different genes or result from different posttranslational modifications of a single coding sequence.

描述: The LUT ovens are designed for drying paint and other coatings where solvents in the air can form explosive atmospheres, where there is a restriction on the maximum quantity of solvent*. The LUT 6050 F is for installation in areas subject to fire hazards, e.g. where laquers are handled. The inner chamber and all fittings are made of 1,4301 stainless steel, and insulating materials are free of surface active substances (no silicone is used). The formation of vapour pockets is avoided by a well directed air supply system, fresh air is filtered and pre-heated before it enters the chamber, a radial fan ensures the heated fresh air and solvent vapours mix efficiently.

描述: Synthesis of cDNA and PCR amplification are carried out in the same tube without opening between procedures. These kits are optimised to deliver maximum RT-PCR efficiency and specificity, enabling unbiased co-amplification of low copy transcripts in the presence of higher copy reference genes. As a result the qScript™ One-Step qRT-PCR Kits offer improved sensitivity over other commercially available qPCR reagents. The qScript™ One-Step Master Mix maximises the activities of both reverse transcriptase and PCR enzymes, while minimising primer-dimer formation. High specificity is assured with AccuStart™ <i>Taq</i> DNA Polymerase, which is bound by monoclonal antibodies for superior hot-start. Upon heating to 95 °C, the antibodies denature irreversibly releasing fully active and unmodified <i>Taq</i> DNA polymerase. qScript™ One-Step qRT-PCR Kits are available for all Real-Time PCR instrument platforms, including those requiring normalisation with ROX reference dye.

描述: Where an AnaeroGen sachet is placed in a sealed jar, the atmospheric oxygen in the jar is rapidly absorbed with the simultaneous generation of carbon dioxide. This novel method differs from others commonly used in that the reaction proceeds with no evolution of hydrogen, and therefore, does not require a catalyst. Furthermore, water is not required to activate the reaction. When used as directed, the AnaeroGen sachet will reduce the oxygen level in the jar to below 1% within 30 minutes. The resulting carbon dioxide level will be between 9% and 13%.
CampyGen Compact for 1 or 2 Petri dishes, is a simple system for generating microaerobic conditions. The system consists of a plastic pouch and sealing clip and a paper gas generating sachet. The paper sachet contains ascorbic acid which reacts on contact with air to produce the microaerobic conditions for the growth of microaerophilic organisms.

Light sensitivity: This tandem dye is sensitive photo-induced oxidation. Please protect this vial and stained samples from light. Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 µL cell sample + 100 µL IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

描述: Guanidine Hydrochloride is a protein denaturant and thus having an important role in molecular weight determinations.
Guanidine Hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Guanidine HCl is used in the isolation of RNA to dissociate the nucleoprotein into its nucleic acid and protein moieties. It is an inhibitor of RNase. Highly concentrated (6 - 8 M) Guanidine HCl solutions are used to denature native globular proteins. It apparently disrupts hydrogen bonds which hold the protein in its unique structure. However, there also is evidence suggesting that guanidine hydrocholoride may disrupt hydrophobic interactions by promoting the solubility of hydrophobic residues in aqueous solutions.

描述: 5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser CD3 complex is crucial in transducing antigen-recognition signals into the cytoplasm of T cells and in regulating the cell surface expression of the TCR complex. T cell activation through the antigen receptor (TCR) involves the cytoplasmic tails of the CD3 subunits CD3 gamma, CD3 delta, CD3 epsilon and CD3 zeta. These CD3 subunits are structurally related members of the immunoglobulins super family encoded by closely linked genes on human chromosome 11. The CD3 components have long cytoplasmic tails that associate with cytoplasmic signal transduction molecules. This association is mediated at least in part by a double tyrosine-based motif present in a single copy in the CD3 subunits. CD3 may play a role in TCR-induced growth arrest, cell survival and proliferation. The CD3 antigen is present on 68-82% of normal peripheral blood lymphocytes, 65-85% of thymocytes and Purkinje cells in the cerebellum. It is never expressed on B or NK cells. Decreased percentages of T lymphocytes may be observed in some autoimmune diseases.
