Fluorescent beads with magnetic or non-magnetic particles

Features

  • FF beads are magnetically separable fluorescent beads, incorporating a fluorescent dye into conventional FG beads.
  • FS beads are nonmagnetic fluorescent beads.
  • Europium is used as a fluorescent dye (Ex: 346 nm / Em: 616 nm)

Application 1: Sandwich immunoassay using FF beads

Application to immunoassay by antibody immobilized FF beads. Because FF beads contain plenty of fluorescent dye, the detection sensitivity of them has become higher than that of the labelled antibodies of the conventional immunoassay. In addition, the reaction efficiency and the measuring speed have been  improved by using a magnet for antigen-antibody reaction.

Detection result of the α-fetoprotein (tumor marker) in human serum

 

Application 2: Immunostaining using FF beads

When staining EGFR receptors in a xenograft specimen of A 431 human  epidermoid carcinoma cell by using FF beads, the result similar to the result of the conventional immunostaining was obtained in a short time.
