Our Abpromise guarantee covers the use of ab67402 in the following tested applications.

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

Application Abreviews Notes
  • Application notesIHC-P: Use at a concentration of 2.5 µg/ml.
    WB: Use at a concentration of 0.5 - 2 µg/ml. Detects a band of approximately <97 kDa (predicted molecular weight: 108 kDa).

    N.B. KA1 often migrates at a lower molecular weight in SDS-PAGE.

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionReceptor 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 similaritiesBelongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIK4 subfamily.
    • Cellular localizationCell membrane. Cell junction > synapse > postsynaptic cell membrane.

    The exact immunogen sequence for ab67402 is proprietary, but I can confirm that it is from within the last 50 amino acids of the human KA1 protein.
    Unfortunately, this antibody currently has not been used in any published papers.
