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.

Electron microscopy (EM) is a microscopy technique that detects the scatter of electrons through thin tissue sections. In Immuno-EM the antigen is usually revealed by colloidal gold conjugated secondary antibodies linking electron dense structures to antigen-bound primary antibodies.
Immunogen Synthetic peptide corresponding to AA 974 to 988 from rat Ribeye (UniProt Id: Q9EQH5-2)
Reactivity Reacts with: human (P56545), rat (Q9EQH5), mouse (P56546), monkey, cow.
Other species not tested yet.
Specificity This antibody recognizes CtBP 2 and ribeye (cat. no. 192 003). K.D. validated PubMed: 28855251
Remarks

The immunogen is identical to that of anti-ribeye (cat. no. 192 003).
IHC: For optimal results, mild fixation (immersion fixation with 4% PFA for 15 min) according to Gierke et al. 2023 is recommended.

Background

CtBP 2 and its close relative CtBP 1 interact with various transcription factors through a PLDLSL motif enhancing transcriptional repression. With the exception of the first 20 amino acids CtBP 2 is identical to the B-domain of ribeye, a scaffolding protein of the ribbon synapse. Both proteins originate from the same gene.
