WB: 1 : 1000 (AP staining) gallery  
IP: not tested yet
ICC: 1 : 500 gallery  
IHC: 1 : 500 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.

Immunogen Synthetic peptide within the SNARE binding domain of mouse Complexin2 (UniProt Id: P84086)
Reactivity Reacts with: mouse (P84086), rat (P84087).
Other species not tested yet.
Predicted to cross-react with human (Q6PUV4) due to high sequence homology.
Specificity Antibody has a strong preference for Complexin2 and shows only minor cross-reactivity with Complexin1.

Complexin2 (red) and Synaptoporin (green) staining in a mouse hippocampus section

Background

Complexins are enriched in neurons where they colocalize with syntaxin1 and SNAP25. In addition, complexin2, also referred to as synaphin1, is expressed ubiquitously at low levels. Complexins bind weakly to syntaxin1 alone and not at all to synaptobrevin and SNAP25, but strongly to the SNAP receptor-core complex composed of these three molecules. They compete with α-SNAP for binding to the core complex but not with other interacting molecules, suggesting that complexins regulate the sequential interactions of α-SNAP and synaptotagmins with the SNAP receptor during exocytosis.
In retinal ribbon synapses complexin3 and complexin4 functionally replace complexin1 (synaphin2) and complexin2. They have similar biochemical binding properties and are farnesylated at their C-terminus.
