Hello Power-Flowers, I have a new idea and according to this many new problems. I need particles for magnetic separation and the ability to control them in the FACS. Surface modification for protein coupling is wanted, but is not necessary. Where can I find paramagnetic FITC labelled polystyrene particles with a diameter of 1 micrometer? Several years ago Polysciences had some in his programm, but they were replaced by a crude mixture of beads of 1 to 10 micrometer - useless for my experiments. Who knows an alternative source of such particles?!?!?!?! Thanks for all help and good luck for your own experiments Joerg Hildmann ----------------------------------- Joerg Hildmann Institut fuer Immunologie Universitaet Mainz Obere Zahlbacher Strasse 67 55313 Mainz - Germany Telefon: +49/6131/17-3988 oder 2119 Fax: +49/6131/39-5688 E-Mail: HILDH000@MAIL.UNI-MAINZ.DE -----------------------------------
