LAG3/CD223 [EPR4392(2)]
Description Lymphocyte activation gene-3 (LAG3), also known as CD223, is a protein expressed by activated CD4+ and CD8+ T cells. This protein binds to major histocompatibility complex (MHC) class II molecules with significantly higher affinity than CD4, and is associated with the T-cell receptor complex at the cell surface. It is hypothesized that LAG3 might act as an important negative competitor of CD4, to modulate T cell proliferation, function and homeostasis. Both MHC class II and LAG-3 are strongly upregulated in inflammatory responses. In tumor tissues, LAG3 has been detected in tumor infiltrating lymphocytes. Immunohistochemical analysis revealed LAG-3 expression was distributed on lymphocytes scattered in renal cell carcinoma, melanoma and lymphomas. They were also detected in the tumor stroma as well as in the peritumoral tissue. In melanoma, expression of MHC II has been associated with poor prognosis. Recently, a study demonstrated that LAG3 can prevent MHC II-positive melanoma cells f Host Rabbit Application Immunohistochemistry (IHC) Reactivity Human

Lambda Light Chain [MD138R]
Description Each immunoglobulin molecule consists of two identical heavy chains and two identical light chains. There are two types of light chains designated as kappa and lambda. The gene rearrangement process that generates the immunoglobulin molecule results in either a productive kappa or lambda gene. The lambda light chain antibody labels the lambda light chain that expresses normal and neoplastic B lymphocytes and plasma cells. Other cells may also express lambda light chain due to nonspecific uptake of immunoglobulin. Individual B cells express either kappa or lambda light chains. Monoclonality is generally assumed to be evidence of a malignant proliferation. The pairing of a kappa with a lambda light chain antibody is useful for identifying monoclonality of lymphoid malignancies.

LEF1/TCF1 Alpha [MD158R]
Description LEF1 or TCF1 alpha participates in the Wnt signaling pathway, activates transcription of target genes in the presence of CTNNB1 and EP300. It may play a role in hair cell differentiation and follicle morphogenesis. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by LEF1 and CTNNB1. It regulates T-cell receptor alpha enhancer function. PIAG antagonizes both Wnt-dependent and Wnt-independent activation by LEF1. Isoform 3 lacks the CTNNB1 interaction domain and may be an antagonist for Wnt signaling. Isoform 5 transcriptionally activates the fibronectin promoter, binds to and represses transcription from the E-cadherin promoter in a CTNNB1-independent manner, and is involved in reducing cellular aggregation and increasing cell migration of pancreatic cancer cells. Isoform 1 transcriptionally activates MYC and CCND1 expression and enhances proliferation of pancreatic tumor cells. Detected in thymus but not detected in normal colon, but highly expressed in colon cancer biopsies a Host Rabbit Application Immunohistochemistry (IHC) Reactivity Human

LGR5/GPR49 [8G9]
Description Leucine-rich repeat containing G protein-coupled receptor 5 (LGR5) is a seven-transmembrane G-protein coupled receptor (GPR49). It belongs to the family of glycoprotein hormone receptor family. LGR5 is present in the endometrium layer. The LGR5 gene is located on human chromosome location 12q21.1. LGR5 binds to R-spondin and enhances the Wnt/ β-catenin pathway. It stimulates tumor progression and induces colorectal cancer development. Lgr5 acts as a potential stem cell marker in numerous adult tissues. It has pathological significance in various cancers, like breast, colon, stomach, liver and esophagus. Elevated expression of LGR5 is associated with breast, ovarian, colon and hepatocellular cancers. Breast cancer patients with high-grade ER- and high levels of LGR5 expression often die due to breast cancer. Most fatal cases of ductal carcinoma in situ (DCIS) were LGR5+. Some studies find that the LGR5 expression pattern can be used as a biomarker to identify patients that need thera Host Rabbit Application Immunohistochemistry (IHC) Reactivity Human

LIN28 [EP150]
Description LIN28 is a highly conserved, RNA-binding protein (RBP). It plays an important role as a translational enhancer, leading specific mRNAs to polysomes and therefore increasing the competence of protein synthesis. LIN28 was identified as a negative regulator of miRNA biogenesis and suggested to play a central role in blocking miRNA-mediated differentiation in stem cells and certain cancers. LIN28 is expressed by various undifferentiated embryonic cell types. Anti- LIN28 has been used as a sensitive marker for germ cell tumors. The positive staining of LIN28 in yolk sac tumors showed an advantage over OCT4, which is negative in these tumors. The nuclear reactivity of this antibody maybe observed in the myoepithelial cells of the salivary gland. (Shipping Cost: €200.00) Host Rabbit Application Immunohistochemistry (IHC) Reactivity Human

LMO2 [SP51]
Description LMO2 is expressed in normal germinal center B-cells and in a subset of lymphomas derived from those cells in addition to bone marrow hematopoietic precursors and endothelial cells. LMO2 protein expression has also been shown to play an important role in the diagnosis of diffuse large B-cell lymphomas, regardless of rituximab treatment. It also plays a role in angiogenesis and hematopoiesis. It is weakly expressed in mantle zone B-cells but not in mantle cell or marginal zone lymphomas. It has been demonstrated that LMO2 is expressed in 70% of follicular lymphomas. These data suggest that anti-LMO2 is a useful adjunct in the diagnosis of follicular lymphoma (FL). As LMO2 appears not to be down regulated in higher grade FL or the interfollicular and diffuse components of FL, its utility in variant immunoarchitectural patterns of FL and in cases that lack CD10 and bcl2, is similar to that of HGAL.
