Coated Microspheres

New Bio-Estapor® product line

A range of bio-activated microspheres are available as superparamagnetic.

Magnetic bioseparation or biopurification of antigens, antibodies or nucleic acids with Estapor® coated microspheres are both a simple and reproducible technique which provide an easier, faster and cheaper alternative to column purification, centrifugation or extraction with organic solvents.

According to the evidence that microsphere requirements for capturing microbial cells (such as E. Coli or Salmonella) are different from those for isolating nucleic acids (DNA, RNA or PCR products) or human cells (T lymphocytes, or B lymphocytes), we now supply small, standard and Large SuperParamagnetic Microspheres.

We are proud to offer you our complete product range of pre-activated magnetic microspheres, coated with the most universal molecules for diagnostic applications : Streptavidin, Avidin and anti-mouse IgG.
 

Used as capture-intermediates, Bio-Estapor® Microspheres offer many advantages for immobilising easily antibodies or antigens onto the surface of your microspheres. As ready-to-use reagents, Bio-Estapor® Microspheres represent a powerful activated solid phase dedicated to many applications (Life Sciences, Biotech, Diagnostics and much more), making your coating procedures and immunoassay developments easier and quicker.
