The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/1000. Detects a band of approximately 106 kDa (predicted molecular weight: 101 kDa).
Application notesIs unsuitable for Flow Cyt or ICC.
FunctionIonotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L-glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist.
Tissue specificityWidely expressed in brain.
Sequence similaritiesBelongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIA1 subfamily.
Post-translational modificationsPalmitoylated. Depalmitoylated upon glutamate stimulation. Cys-603 palmitoylation leads to Golgi retention and decreased cell surface expression. In contrast, Cys-829 palmitoylation does not affect cell surface expression but regulates stimulation-dependent endocytosis.
Ab32436, at a 1/50 dilution, staining Glutamate Receptor 1 (AMPA subtype) in paraffin embedded human brain tissue by Immunohistochemistry.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Glutamate Receptor 1 (AMPA subtype) antibody [E308] (ab32436)Image from van Vuurden DG et al., PLoS One. 2009 Jun 18;4(6):e5953. Fig 2.; doi:10.1371/journal.pone.0005953; June 18, 2009, PLoS ONE 4(6): e5953.
Immunohistochemical analysis of Human hippocampus tissue, staining Glutamate Receptor 1 (AMPA subtype) with ab32436.
Antigen retrieval was performed by heat mediation in a citrate buffer (pH 6). Samples were blocked with 10% normal goat serum for 30 minutes before incubating with primary antibody (1/20) for 2 hours. A biotinylated anti-rabbit IgG was used as the secondary antibody and staining was detected using DAB.
