ALK/CD246 Antibody (SP8)

Product: XMU-MP-1

ALK/CD246 Antibody (SP8) Summary

Immunogen
Recombinant protein corresponding to a region, which spans the tyrosine kinase catalytic domain and part of the C-terminus of the NPM-ALK transcript
Localization
Cell Membrane
Specificity
This antibody recognises a human p80 protein, identified as a hybrid of the anaplastic lymphoma kinase (ALK) gene and the nucleophosmin (NPM) gene resulting from the t(2;5)(p23;q35) translocation found in a third of large cell lymphomas. This rabbit monoclonal antibody can be used to detect p80 in these lymphomas and may also be used to detect a recently described subtype of large B cell lymphoma, which expresses the full-length ALK protein.

Background

Anaplastic lymphoma kinase (ALK) was originally discovered as a NPM (Nucleophosmin)-ALK fusion protein. ALK and LTK (leukocyte tyrosine kinase) are receptor tyrosine kinases similar to the insulin receptor subfamily of kinases. LTK is found in murine B Lymphocyte precursors and in forebrain neurons. ALK is usually found in the nervous system. A truncated form of ALK occurs in many non Hodgkins lymphomas. The ALK gene is on chromosome 2. Upon translocation between chromosome 2 and chromosome 5 [t(2;5}], the ALK gene fuses with the NPM gene. NPM, also known as B23, is an ubiquitous nucleolar phosphoprotein involved in the transport of pre ribosomal components between the nucleolus and the cytoplasm. The chimeric product (NPM ALK) resulting from t(2;5) translocation is a protein of 80kDa with the N terminal portion of NPM linked to the complete intracellular portion of ALK. Karpas 299 and SUDHL1 lymphoid cell lines strongly express NPM ALK.
