Isotype

Mouse IgG1

Specificity

The antibody NAP-07 reacts with an intracellular epitope of Non-T cell activation linker (NTAL), also known as LAB (linker of activated B cells), a 25 - 30 kDa transmembrane adaptor protein associating with lipid raft components in the plasma membrane of B lymphocytes, NK cells and myeloid cells.

Application

FC (QC tested)

Application details

Flow cytometry: Intracellular staining; recommended dilution: 1-5 μg/ml; positive tissue: RAJI human lymphoma cell line, RAMOS human lymphoma cell line.

Reactivity

Human, Mouse

Immunogen

Recombinant cytoplasmic domain (aa 91-243) of human NTAL.

Antigen description

NTAL (non-T cell activation linker), also known as LAB (linker for activation of B cells), is a 30 kDa double-palmitoylated transmembrane adaptor protein expressed by B cells, NK cells, mast cells and macrophages. It is a negative regulator of early stages of BCR-dependent B cell signaling and serves as a negative regulator also in mast cells. However, in mast cells, NTAL also contributes to some activation processes, partially overlapping with LAT function.
