  • Blocking SolutionQuick view

    AURION Blocking Solutions

    Request for Quotation

     

    The AURION Blocking Solutions are used to prevent immunoreagents from binding non-specifically to specimens with “sticky” surface properties.

    Procedures to eliminate background comprise three main steps:

    • To suppress residual aldehyde activity
    • To saturate multipoint hydrophobic moieties and positive charges with high molecular weight compounds such as those present in the AURION Blocking Solutions
    • To reduce aspecific binding of immunoreagents caused by hydrophilic interaction with competing molecules in the incubation and washing solution. AURION BSA-c™ is a particularly effective reagent for this purpose.

  • AURION BSA-c Incubation Solution AdditiveQuick view

    AURION BSA-c™ Incubation Solution Additive

    Request for Quotation

     

    AURION BSA-c™ is a buffer additive that helps prevent immunodetection reagents (i.e. primary antibodies and secondary reagents) from binding nonspecifically to charged moieties within the specimen. Thus, it suppresses background competitively with little or no effect on the specific reaction. Its successful application is not limited to immunogold detections but it is equally efficient in fluorescent and enzyme-based detection systems. AURION BSA-c™ concentrations as low as 0.01-0.1% inhibit binding of  gold conjugate to polycationic poly-l-lysine coated grids almost completely (>99%).

    • To suppress residual aldehyde activity
    • To saturate multipoint hydrophobic moieties and positive charges with high molecular weight compounds such as those present in the AURION Blocking Solutions
    • To reduce non-specific binding of immunoreagents caused by hydrophilic interaction with competing molecules in the incubation and washing solution.

    The surface properties of the specimen can be simplified by division into four compartments:
    - negatively charged (polyanions, proteins, especially after aldehyde fixation, lipids);
    0  neutral;
    + positively charged (histone proteins, polycations) and
    H hydrophobic (lipids, fat droplets, resins). After an appropriate blocking step these areas are covered with blocking compounds.

  • Immunogold Reagents TechniqueQuick view

    AURION Conventional Immunogold Reagents and Application Technique

    Request for Quotation

     

    Conventional Immunogold Reagents are available in four size classes. The monodisperse size population makes the conjugates suited for multiple labeling with no overlap. The Conventional Immunogold Reagents are the classical conjugates in immuno electron microscopy; they are a good choice when the antigen is abundant and the accessibility of the antigen is relatively good.

  • quantima_smallQuick view

    GBC Quantima ICP-OES

    Request for Quotation

    .

    In ICP Analysis, the Quantima offers many new innovative features including the Plasma Cam and PIP. Patented PIP (Plasma Integrity Protection) significantly reduces parasitic plasma or 'donuts' from melting the torch. The plasma cam allows easy viewing from the PC screen. The Quantima is very cost effective. At 11 l/min for a typical aqueous sample, this is the lowest Argon consumption of any ICP-OES analysis currently available. In addition, the Quantima's torch ignition sequence has been greatly improved. The New IIS Intelligent Ignition Startup will vary the plasma startup sequence routine depending on how long the plasma has been off. This enables quicker startup routine for a plasma recently turned off. The Quantima is able to analyse slurry and high dissolve solids without dilutions or digestion to enhance productivity. Organic samples can be directly aspirated without oxygen accessories. With over 32,000 wavelengths for selection and 4pm resolution guaranteed, the Quantima enables analysis of compex matrices.

    QX-202C Capsules — For in-situ imaging of dynamic hydration processes

    Request for Quotation

     

    QX-202C capsules are used for in-situ SEM imaging of various dynamic hydration processes. They can be used for imaging the hydration process of cement, gypsum and other materials. The unique design of the QX-202C capsules allows extended studies to be performed inside the SEM vacuum chamber - the dynamic process can be followed for up to 24 hours, removing the need for multiple-sample imaging or repetitive venting of the SEM. There is no need for coating, drying or freezing of the samples. Simply place the sample in the capsule, seal it and image. The samples can be visualized directly using a BSE detector.

    The following images show the early stages of gypsum hydration; the growth of needle like crystals can be followed in the sequence of micrographs. Images were taken at 8, 16, 24, and 60 minutes. The formation of a network of gypsum crystals is evident within the first hour of observation.
