Application Abreviews Notes
Blocking Use at an assay dependent concentration. PubMed: 19204785
WB 1/2000. Detects a band of approximately 180 kDa.

For unpurified use at 1/500.

IP 1/20.

For unpurified use at 1/50.

IHC-P 1/1000 - 1/2000. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

See IHC antigen retrieval protocols.

  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.
  • Target

    • Function
      In case of filovirus infection, seems to function as a cell entry factor.
    • Tissue specificity
      Not expressed in normal B- and T-lymphocytes but is expressed in numerous neoplastic B- and T-cell lines.
    • Involvement in disease
      Defects in MERTK are the cause of retinitis pigmentosa type 38 (RP38) [MIM:613862]. RP38 is a retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.
    • Sequence similarities
      Belongs to the protein kinase superfamily. Tyr protein kinase family. AXL/UFO subfamily.
      Contains 2 fibronectin type-III domains.
      Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
      Contains 1 protein kinase domain.

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human lymphoma tissue labelling MERTK with unpurified ab52968 at a 1/50 dilution.

    • All lanes : Anti-MERTK antibody [Y323] (ab52968) at 1/2000 dilution (purified)

      Lane 1 : HEK293 cell lysate
      Lane 2 : K562 cell lysate

      Lysates/proteins at 20 µg per lane.

      All lanes : Peroxidase-conjugated goat anti-rabbit IgG at 1/1000 dilution

      Observed band size: 140-180 kDa (why is the actual band size different from the predicted?)
