The DURAClone RE panels enable sensitive detection of rare abnormal cell populations in blood or bone marrow using carefully optimized and titrated antibody combinations. Mature human peripheral B cells (CD45+CD19+ lymphocytes) express high density levels of the antigens CD20, CD79b and CD81 on their surface. In contrast, the antigens CD5, CD43 and ROR1 are expressed at low density in a small fraction of these cells. Expression patterns involving high expression of CD5, CD43 and ROR1 accompanied by reduced expression of CD20, CD79b, and CD81 can be utilized to identify abnormal mature B cells even at very low frequencies.

  • Combination of 8 markers for sensitivity detection of abnormal mature B cells, including CD5, CD19, CD20, CD43, CD45, CD79b, CD81, ROR1
  • Pre-formulated antibody panel in a dry unitized assay eliminating antibody cocktailing
  • 25 tests per kit including 3 compensation kits with lot matched tandem dyes

For Research Use Only. Not for use in diagnostic procedures.
