Lambda
Each test contains a set of oligonucleotide probes. The intended target is the lambda light chain immunoglobulin messenger RNA (mRNA) in the cytoplasm of immunoblastic cells, plasma cells and plasmacytoid cells. Assessing the light chain immunoglobulin restriction is important in malignant lymphoma
In Situ Hybridization (ISH)
Lambda (Lambda Light Chain IgG) by IHC
Antibody to the lambda light chain of immunoglobulin is reportedly useful in the identification of leukemias, plasmacytomas and certain non-Hodgkin lymphomas. Demonstration of monotypism in lymphoid infiltrates is a surrogate for clonality, and therefore malignancy.
Immunohistochemistry (IHC)
Langerin
Langerin is a highly selective marker for Langerhans cells and the lesional cells of Langerhans cell histiocytosis. Langerin protein expression has utility in differentiating Langerhans cell histiocytosis from other non-Langerhans cell histiocytic proliferations.
Immunohistochemistry (IHC)
LEF1
LEF1 overexpression is highly associated with CLL/SLL among small B-cell lymphomas and may serve as a useful marker for diagnosis and differential diagnosis of the disease.
Immunohistochemistry (IHC)
LH
Luteinizing Hormone (LH) is a tropic hormone that modulates the secretory activity of other endocrine glands. It is produced in the anterior hypophysis of the pituitary gland. LH antibody is useful for the labeling of normal gonadotropic cells of the pituitary and also for the classification of
Immunohistochemistry (IHC)
LMO2
LMO2 protein is expressed in normal human germinal-center (GC) and GC-derived lymphomas. In addition, it is also expressed at high levels in endothelial cells, spleen, hematopoietic precursors, and a significant proportion of acute lymphoblastic and myeloid leukemias. In diffuse large B-cell

Low-Grade/Small B-Cell Lymphoma FISH Panel
Probes: BCL6 (3q27) | CCND1/IgH t(11;14) IgH/BCL2 t(14;18) | MALT1 (18q21) Probes may be ordered separately. Disease(s): NHL, B-Cell Lymphoma, MCL, follicular lymphoma, MZL, MALT lymphoma
FISH
Lynch Syndrome
This test is performed by sequencing the entire EPCAM, MLH1, MSH2, MSH6 and PMS2 genes using next-gen sequencing complemented by conventional Sanger sequencing or other molecular methodologies to detect point mutations, small insertions/deletions, and large deletions/duplications. Testing may be
Molecular
Lysozyme
Lysozyme is synthesized predominantly in reactive histiocytes rather than in resting, unstimulated phagocytes. This antibody labels myeloid cells, histiocytes, granulocytes, macrophages and monocytes. It is helpful in the identification of myeloid or monocytic nature of acute leukemia.
