Glutamate transporters (GluT) function to remove L-glutamate (Glu), the primary excitatory neurotransmitter in the mammalian central nervous system (CNS), from the synaptic cleft. By clearing the synapse in this manner, Glu can be recycled for later use, the proper diffusion gradient can be maintained and excitotoxicity can be prevented.There have been reports of at least three different members of a GluT multigene family; GLT-1, GLAST and EAAC1. mRNA has been identified in brain for each of these proteins, while EAAC1 mRNA has also been shown to be transcribed in other tissues. GLT-1 is translated in numerous CNS regions including cerebellum, thalamus, hippocampus, midbrain and spinal cord. Unmodified GLT-1 has a calculated mass of 62kDa protein (~75kDa after post-translational modifications) in rat brain homogenates. A 51kDa species resulting from an alternate translation initiation site has also been detected in rat brain homogenates.

PA3-040A detects glutamate transporter 1 (GLT-1) from rat tissues.PA3-040A has been successfully used in Western blot and immunoprecipitation procedures. By Western blot, this antibody detects a ~61kDa band representing GLT-1 from rat brain extract. This antibody may also detect one or more non-specific bands below 50kDa that have not been identified.The PA3-040A immunogen is a synthetic peptide corresponding to residues N(556) G K S A D C S V E E E P W K R E K(573) or rat GLT-1. While GLT-1, GLAST and EAAC1 share approximately 50% sequence homology, the sequence used to generate this product is unique to GLT-1.
