The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately <97 kDa (predicted molecular weight: 107 kDa).
ICC/IF Use a concentration of 20 µg/ml.
IHC-P Use at an assay dependent concentration.


  • Function
    Receptor for glutamate. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists.
  • Sequence similarities
    Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIK4 subfamily.
  • Cellular localization
    Cell membrane. Cell junction > synapse > postsynaptic cell membrane.

    Predicted band size : 107 kDa
    Observed band size : <97 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 108 kDa. We are unsure as to the identity of these extra bands.
  • ab67404 at 2.5µg/ml staining of KA1 in human brain tissue by IHC-P.
  • ICC/IF image of ab67404 stained SKNSH cells. The cells were 4% PFA fixed (10mins) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab67404, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
