Lymphoclonal™-9 is a 6-color mixture designed to simultaneously determine, in peripheral blood, bone marrow and other body fluids, the major lymphocyte subpopulations including T-cells (CD3+), B-cells (CD19+ CD20+) and NK-cells (CD3- CD56+), as well as helper (CD3+ CD4+) and cytotoxic (CD3+ CD8+) T-cell subsets and B-cell subsets with light chain immunophenotype Kappa (CD19+ SmIgκ+) and Lambda (CD19+ SmIgλ+).

In comparison to the Lymphoclonal™ kit, this combination also includes CD45 and CD20 antibodies for improved lymphocyte population identification and B-cell characterization respectively. Furthermore, the lyophilized form provides a more stable mixture.
