Lymphoclonal™-12 is a 12-color mixture for screening of B-cell lymphoma within a variety of clinical samples when the pre-test probability is low or unknown. This is particularly useful in paucicellular specimens such as fine needle aspirate, core biopsy, pleural, ascitic and cerebral spinal fluid (CSF) where limited sample is available.

In comparison to the Lymphoclonal™-9 kit, this combination also includes CD5 and CD10 antibodies, making possible complete assessment of normal B-cell maturation and subclassification of B-cell lymphoma, and CD38 antibody for the identification of other leukocyte populations (e.g. plasma cells). Likewise, the lyophilized form provides a more stable mixture.
