  • Product Detail
  • Company Profile

    Specification: 10 mL,20 mL, 50 mL, 100 mL
    Size: 100 nm, 300 nm
    Storage: Stored at  2-8°C  for 6 months.
    Saturation magnetization:  > 10 emu/g
    The surface of the supper paramagnetic Fe3O4 nanoparticles is covalently functionalized with streptavidin, can be used to bind biotin-conjugated molecules, such as antibody, protein, peptide, DNA primers, etc., through high affinity interaction between streptavidin and  biotin.
    The Streptavidin-biotin-biomolecule complex is easy to be separated from unbound biotin-biomolecule using a magnet, therefore providing a quick and neat way to tag biomolecules with magnetic nanoparticles. The purified nanoparticle-biomolecule complex can be used in a variety of downstream bio-separation processes: protein purification, immunoprecipitation, cell isolation or depletion, and molecular detection.
    Cell Enrichment
    Ecalbio™ Streptavidin  magnetic  nanoparticles are  ideal  for isolation or depletion of cells (e.g.  CTCs, stem cells) from a mixture of cell population obtained from tissues or organs. The isolated  cells are viable and can be further cultured or used for downstream  molecular analysis such as mRNA isolation and RT- PCR. Cell separation with Ecalbio™ eliminates the use of columns, so cells are not exposed to the mechanical stress from passing through the column matrix. Magnetically separated  cells are highly purified and retain their viability, ideal for downstream applications.
    •  Easy and quick to make nanoparticle-antibody  conjugates through streptavidin-biotin  association
    •  Simple and gentle cell separation
    •  Consistent, high quality results
    •  High binding capacity
    •  High biocompatibility
    •  Low non-specific binding
