Coated beads
Since its creation, Indicia Biotechnology has developed and consolidated a specific skill for attaching biomolecules to the surface of microparticles.
Microspheres are very interesting to use:
- Many benefits :
- High reactive surface,
- Low volume of sample and analytes needed,
- Chemically active surface,
- Heterogeneous reactinal phase,
- Colloidal suspension…
- Versatile : reagents used in a wide range of in vitro technologies
- Immunoassays on biochemical or clinical analysis instruments,
- Immunochromatographic tests,
- Agglutination tests,
- Magnetic separation method,
- and so on…
Our offer
Our unique know-how and experience allows us to select the best support for your final application: we follow your precise specifications, or we can also help you to choose the characteristics for the best support:Indicia Biotechnology is known as an expert in the development and manufacturing of micro and nanoparticle based-reagents (bead coupling/conjugation).
- size: from few nanometers to several microns,
- surface: plain or modified such as -COOH, -NH2, -OH, …
- hydrophobicity,
- nature of the beads : magnetic, fluorescent, dyed, white,
- binding protocol adapted to your final application,
- definition of the density for binding analytes.
Indicia Biotechnology adapts to your needs, using microparticles from varied nature:
- magnetic: main applications are immunoassays, high throughput screening, cell sorting, rapid tests, bacteria detection, and so on…
- latex/polystyrene: particularly suited for immunochromatographic, latex agglutination and turbidimetry tests.
- dyed: enable to see colored bands without specific instrument on immunochromatographic tests. A large panel of colors is available (blue, red, black, yellow, green…).
- fluorescent: photostable, and made in polystyrene or polyvinyltoluene. A large choice of fluorescent dyes, depending on the excitation and emission wavelength desired.
Focus on magnetic separation method
Linked to a molecule which is capable of recognising a specific target, the magnetic microsphere constitutes a choice reagent that allows molecules or microorganisms to be extracted by means of a simple magnet. Indicia Biotechnology put their expertise at your fingertips for the development of sample preparation methods in the framework of specific problem areas, particularly in industrial microbiology.
