Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section.

Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section.

Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section.

Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section.

Background

Glutamate is the major excitatory neurotransmitter in the central nervous system. During neurotransmission it is released from synaptic vesicles into the synaptic cleft and is sensed by post-synaptic glutamate receptors (GluAs) (1).
Excitatory amino acid transporters (EAATs) translocate extracellular glutamate into neighbouring astrocytes where it is converted to glutamine by glutamine synthetase (2, 3, 4).
The glutamine is shuttled back to neurons where it is processed to glutamate by glutaminases (GLS) (5). This postulated Glu/Gln cycle is a key mechanism for the homeostatic control of these amino acids.
In humans, three isoforms (GLS1, 2 and 3) have been described. GLS1 is highly expressed in brain and kidney whereas GLS2 is mainly expressed in cardiac and skeletal muscle. GLS3 shows a broader tissue distribution (5). The GLS1 precursor is processed to a 65 and 68 kDa chain.
