Our Abpromise guarantee covers the use of ab31232 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 100 kDa.Can be blocked with Human Glutamate Receptor 1 (AMPA subtype) peptide (ab28424).|
|IHC-FoFr||Use at an assay dependent concentration.|
|IHC-P||Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
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.
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.
Cellular localizationCell membrane. Endoplasmic reticulum membrane. Cell junction > synapse > postsynaptic cell membrane. Interaction with CACNG2 promotes cell surface expression.

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab31232 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.
Immunohistochemistical detection of Glutamate Receptor 1 (AMPA subtype) with ab31232 on formaldehyde-fixed paraffin-embedded rat cerebellum sections. Antigen retrieval step: heat mediated in citric acid pH6. Blocking step: 1% BSA for 10 mins @ rt°C. Primary antibody was incubated at 1/200 for 2 hours @ room temp. Secondary antibody: anti-rabbit IgGs conjugated to biotin (1/200). The composite image shows localisation of this protein apparently exclusive to the molecular layer of the cerebellum upper image (low power). In the lower image (higher power), the molecular layer positivity appears to be compartmentalised/restricted.
ab31232 staining Glutamate Receptor 1 in rat brain tissue section by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue from 4% PFA perfused animals underwent overnight fixation in 4% paraformaldehyde, cryoprotected in 30% sucrose and cut using cryostat.The primary antibody was diluted, 1/3000 (PBS + 0.3% Triton X100) and incubated with sample for 18 hours at 20°C. An abcam antibody ab60314, Chromeo488 conjugated goat polyclonal to rabbit IgG, diluted 1/1000 was used as secondary.
Immunohistochemistical detection of Glutamate Receptor 1 (AMPA subtype) with ab31232 on formaldehyde-fixed paraffin-embedded mouse brain sections. Antigen retrieval step: heat mediated in Citric acid pH6 buffer.Blocking step: 1%BSA for 10 mins @ rt°C. Primary antibody ab31232 incubated at 1/100 for 2 hours. Secondary antibody: anti-rabbit IgGs conjugated to biotin (1/200). The composite image shows immunostaining in cell bodies and processes of a subset of neurones in the mouse cortex (upper image) and also in the dendritic fields of the molecular layer of the mouse cerebellum (lower image). Purkinje cells of the cerebellum are negative but their primary processes are clearly delineated by a punctate membrane-region positivity. What appears to be small cells in close contact with the Purkinje cell bodies are strongly positive (perhaps these are basket cells?).
