Our Abpromise guarantee covers the use of ab59721 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
WB Use a concentration of 2.5 µg/ml. Detects a band of approximately 64 kDa (predicted molecular weight: 58 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 4 - 8 µg/ml.


  • FunctionFunctions as a sodium-dependent amino acid transporter. Mediates the saturable, pH-sensitive and electrogenic cotransport of glutamine and sodium ions with a stoichiometry of 1:1. May also transport small zwitterionic and aliphatic amino acids with a lower affinity. May supply glutamatergic and GABAergic neurons with glutamine which is required for the synthesis of the neurotransmitters glutamate and GABA.
  • Tissue specificityExpressed in the cerebral cortex by pyramidal and GABAergic neurons, astrocytes and other non-neuronal cells (at protein level). Expressed in placenta, heart, lung, skeletal muscle, spleen, stomach and testis.
  • Sequence similaritiesBelongs to the amino acid/polyamine transporter 2 family.
  • Cellular localizationCell membrane. Restricted to the somatodendritic compartment of neurons. Found in the cellular processes of neurons in the developing brain (By similarity).
