Elaine, Please see ref: Science; Vol.274, 4, October 1996. This procedure is described by John Altman et al. The tetramers, because they and made with PE, are actually very bright but because of the frequency you will need to collect at least 100,000 events. I believe the NIH repository is offering samples for analysis which we are currently using. Please see...www.niaid.nih.gov/repost/ tetramer/listing Stephen P. Perfetto, MS.,MT.

From: Elaine Kunze <mek4@psu.edu> at Internet_Gateway Date: 4/26/99 10:54 AM One of my faculty came back from a meeting saying "All the immunologist do a tetramer assay for antigen presenting cells." I feel silly but I never heard of this and didn't find anything after a quicky look at Current protocols and a few other generic sources. Can anyone provide a reference and or explanation? **************************************************************************** Elaine Kunze Flow Cytometry.....Image Analysis...
