A guide to the choosing the best astrocyte markers.
Astrocytes are star-shaped glial cells and serve a wide variety of functions in the central nervous system, which are vital for brain development, physiology and pathology.
GFAP
An intermediate filament and major component of the astrocyte cytoskeleton.
Mouse brain tissue sections stained with anti-GFAP (ab7260).
EAAT1/GLAST
An astrocyte-specific glutamate transporter.
Zebrafish retina tissue sections stained with anti-EAAT1 (green) (ab416).
Browse all EAAT1/GLAST antibodies
Selective EAAT1 inhibitors: UCPH-101 (ab120309) and UCPH-102 (ab146404)
EAAT2/GLT-1
An astrocyte-specific glutamate transporter.
Mouse brain tissue sections stained with anti-EAAT2 (green) (ab41621).
Browse all EAAT2/GLT-1 antibodies
Selective EAAT2 inhibitor: Dihydrokainic acid (ab120066)
Stimulator of EAAT2 expression: Ceftriaxone (ab120871)
Potent and competitive EAAT1-4 inhibitors: L-(-)-threo-3-Hydroxyaspartic acid (ab146130) and L-trans-Pyrrolidine-2,4-dicarboxylic acid (ab146131)
Glutamine synthetase
An enzyme involved in the metabolism of nitrogen. In the brain it is primarily found in astrocytes.
Rat brain tissue sections stained with anti-glutamine synthetase (ab73593).
S100 beta
A calcium binding protein, also found in oligodendrocyte precursor cells (OPCs) Double labeling with NG2 will distinguish the OPCs from the astrocytes.
Mouse brain tissue sections stained with anti-S100 beta (ab52642).
ALDH1L1
An enzyme that catalyzes the conversion of 10-formyltetrahydrofolate, NADP+ and water to tetrahydrofolate, NADPH and CO2.
Mouse brain tissue sections stained with anti-ALDH1L1 (red) (ab87117).
