Product Overview
This rabbit polyclonal antibody targets excitatory amino acid transporter 2 (gene SLC1A2) in mouse and rat samples and is validated for ICC/IF, IHC and Western blot. The predicted molecular weight is 62.1 kDa, and the supplier reports an observed band at about 65 kDa.
Excitatory amino acid transporter 2 (EAAT2, SLC1A2; also known as GLT-1) is the main glutamate transporter of astrocytes in the forebrain. Coupled to sodium and potassium gradients, it clears most of the glutamate released at synapses, protecting neurons from excitotoxicity, and it is widely studied in epilepsy, ALS and other neurological conditions.

Samples with a confirmed band (WB): rat brain tissue, mouse brain tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): mouse brain tissue, rat brain tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): mouse brain tissue, rat brain tissue.
Immunogen
Recombinant human EAAT2 fragment (Thr461–Lys574), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 96%.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt places excitatory amino acid transporter 2 in the cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
