Product Specific Information

Description: This HMER5DS antibody recognizes human MerTK, known also as Mer or c-mer, a 170-210 kDa member of the TAM family of tyrosine kinase receptors that also includes Axl and Tyro3. MerTK is expressed on a subset of anti-inflammatory macrophages and is involved in the removal of apoptotic cells. This process relies on two soluble ligands of Mer,TK Protein S and Gas6, that coat the surface of cells undergoing apoptosis. Upon binding these ligands, MerTK undergoes autophosphorylation at multiple tyrosine residues that activate the PI3K and Akt pathways. This results in the phagocytosis of target cells and also the direct inhibition of TLR-induced production of pro-inflammatory cytokines by the phagocytes. Mer may also function as a putative entry receptor for filoviruses. Deficiency of MerTK causes general autoimmunity, inflammation, and accumulation of apoptotic bodies. MerTK can be released from the cell surface by metalloproteinases, and this process is significantly enhanced when macrophages are stimulated, e.g. with LPS. MerTK is often expressed on malignant cells, and may be implicated in immune evasion.

Applications Reported: This HMER5DS antibody has been reported for use in flow cytometric analysis.

Applications Tested: This HMER5DS antibody has been pre-titrated and tested by flow cytometric analysis of human monocyte-derived macrophages. This can be used at 5 µL (0.06 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.

Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333-34) for up to 3 days in the dark at 4 degrees C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

Excitation: 488-561 nm; Emission: 775 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.

Target Information

MERTK (cMER) is a tyrosine kinase proto-oncogene and is involved in the retinal pigment epithelium (RPE) phagocytosis pathway, which is implicated in human retinal disease. Regulates many physiological processes including cell survival, migration, differentiation, and phagocytosis of apoptotic cells (efferocytosis). Ligand binding at the cell surface induces autophosphorylation of MERTK on its intracellular domain that provides docking sites for downstream signaling molecules. Following activation by ligand, interacts with GRB2 or PLCG2 and induces phosphorylation of MAPK1, MAPK2, FAK/PTK2 or RAC1. MERTK signaling plays a role in various processes such as macrophage clearance of apoptotic cells, platelet aggregation, cytoskeleton reorganization and engulfment. Functions in the retinal pigment epithelium (RPE) as a regulator of rod outer segments fragments phagocytosis. Plays also an important role in inhibition of Toll-like receptors (TLRs)-mediated innate immune response by activating STAT1, which selectively induces production of suppressors of cytokine signaling SOCS1 and SOCS3.
