Applications
 
WB: yes limited (see remarks)
IP: yes
ICC: 1 : 500 (see remarks) gallery  
IHC: 1 : 500 up to 1 : 2000 (see remarks) gallery  
IHC-P: not tested yet
IHC-Fr: 1 : 500 (see remarks) gallery  

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.

Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Immunohistochemistry on fresh frozen (IHC-Fr) cryo-tissue-sections. In contrast to standard PFA perfusion fixed tissues, fresh frozen cryo-tissue-sections can be variably postfixed with alcohols, acetone or PFA. Alcohol or acetone fixation is e.g. of advantage for antigens masked by PFA crosslinking. For recommended postfixation, please refer to the ”Remarks” section. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.

Immunogen Synthetic peptide corresponding to AA 39 to 67 from mouse GABA-A receptor γ2 (UniProt Id: P22723)
Reactivity Reacts with: human (P18507), rat (P18508), mouse (P22723).
Other species not tested yet.
Specificity Specific for GABA-A receptor γ2. Does not discriminate between the L and S form.
Matching control protein/peptide 224-0P
Remarks

WB: The antibody is less sensitive in westernblotting compared to the rabbit antibody. GABA-A receptor gamma2 aggregates after boiling, making it necessary to run SDS-PAGE with non-boiled samples.
ICC: This antibody is also suitable for the surface staining of living cells. After washing cells with bound antibodies, they can be fixed and visualized with secondary reagents.
IHC: For best results use the protocol of Schneider Gasser et al., 2006.

Heat-mediated antigen retrieval (in citrate buffer pH 6) is required for immunohistochemical staining.
IHC-Fr: PFA fixation is recommended.

Background

Gamma-aminobutyric acid type A (GABA-A) receptors mediate the majority of inhibitory neurotransmission in the brain. These receptor proteins are ligand gated chloride ion channels and consist of a pentameric combination of different subunits (alpha, beta, gamma, delta, epsilon and rho). The resulting heterogenous population of GABA-A receptor subtypes are expressed throughout the brain with specific cellular and subcellular expression patterns.
