Technical Information


Product Categories



  • BioMag®

    BioMag particles have a tremendous surface area, and are ideal for conducting bioseparations from a range of samples.  The higher density of BioMag allows them to perform well even in difficult (e.g. highly viscous or complex) samples that can be problematic from polymer microspheres.  A variety of surfaces are available, including secondary antibodies, protein A and G, anti-CD markers, oligo dT, as well as functionalised versions for fully customised coatings.


    Highly uniform magnetic microspheres in diameters of 3, 6 and 8 µm. They are ideal for applications in flow cytometry.  Beads contain a highly optimised amount of magnetite to minimise settling during incubation steps, while ensuring rapid separation times.  The polymer matrix is conducive to dyeing, and standard red and green fluorescent versions are available.

  • ProMag™

    The newest addition to the magentic microsphere product line, these 3 µm polymer based magentic spheres support diagnostic applications that require highly uniform, high-binding beads and fast separation times.  ProMag have a proprietary hydrophilic surface to reduce non-specific binding in protein-based systems, and offer superior handling without the use of surfactant.

    Fluorescent Reference Standards for daily standardisation to ensure optimal and reproducible instrument performance.

  • Reference Standards

    Fluorescent labels from Bangs make an ideal reference material for instrument standardisation.

  • Right Reference Standard™

    Standards which provide an internal point of reference for stained cell populations.

SNARe DNA Purification kits™

SNARe™ DNA Purification Systems offer rapid, cost-effective methods for isolating DNA using DNA Separation Particles.  DNA Separation Particles are a suspension of superparamagnetic iron oxide particles that bind double-stranded DNA. Once bound, the DNA-particle complex is stable and can be washed to remove any impurities or unwanted proteins from the sample to provide a clean DNA preparation.

Polymer Microspheres



Bangs Laboratory's flow cytometry product suite includes products to check general instrument status, optics alignment, sensitivity, and linearity. We also have numerous products to aid in establishing instrument settings, such as PMT voltages and compensation, and designing a comprehensive flow cytometry QC program. Read More     Superparamagnetic particles have been utilised extensively in diagnostics and other research applications for the purification of cells and biomolecules, such as antibodies, nucleic acids, and polypeptides. They confer a number of benefits, including ease of separation and suitability for automation. When coated with recognition molecules, magnetic microspheres are ideal for the efficient capture and separation of target.

    Microsphere size may be critical to the proper function of an assay, or it may be secondary to other characteristics. Considering traditional diagnostic methods, the test or assay format commonly dictates particle size, such as the use of very small spheres (~0.1-0.4µm) to ensure satisfactory wicking in lateral flow tests, or the use of larger, cell-sized spheres (~4-10µm) for bead-based flow cytometric assays.  Read More     Polymer microspheres present a flexible platform for applications in diagnostics and bioseparations. They may be coated with recognition molecules, such as antibodies, antigens, peptides, or nucleic acid probes, and can be loaded with hydrophobic dyes and other compounds. Unmodified polymer spheres also find extensive use as standards for instrument set-up and calibration. Read More
