Purity Affinity purified on immobilized antigen.

Form Lyophilized powder. Reconstituted antibody contains phosphate buffered saline (PBS), pH 7.4, 1% BSA, 0.05% NaN₃.

Isotype Rabbit IgG.

Specificity This antibody will recognize both CNIH2 and CNIH3, but not the related proteins CNIH1 and CNIH4.

Storage before reconstitution The antibody ships as a lyophilized powder at room temperature. Upon arrival, it should be stored at -20°C.

Reconstitution 25 µl, 50 µl or 0.2 ml double distilled water (DDW), depending on the sample size.

Antibody concentration after reconstitution 0.8 mg/ml.

Storage after reconstitution The reconstituted solution can be stored at 4°C for up to 1 week. For longer periods, small aliquots should be stored at -20°C. Avoid multiple freezing and thawing. Centrifuge all antibody preparations before use (10000 x g 5 min).

Standard quality control of each lot Western blot analysis.

Applications: wb

May also work in: ic*, ifc*, ih*, ip*, lci*

Scientific background

Cornichon homologs (CNIHs) are a family of AMPA-type glutamate receptor (AMPAR) auxiliary subunits that modulate AMPAR ion channel function and trafficking. Cornichon 2 and 3 (CNIH2/3) are responsible for controlling the export of AMPARs from the endoplasmic reticulum and associate with synaptic AMPARs to modulate channel kinetics^1,2.

CNIHs are small proteins with three transmembrane domains that directly binds to AMPARs. Overexpression CNIHs and AMPA receptors causes their localization to the Golgi apparatus³.

CNIH and TARP both compete for the binding to AMPAR subunits GluA2, GluA3, and GluA4 subunits suggesting both proteins bind to the same site. CNIH2/3 binding to AMPARs is dependent on AMPAR subunit composition and TARPs^3,4.

CNIH2/3 knock out mice shows alterations in synaptic content of GluA1-containing AMPARs, resulting in a reduction in AMPAR-mediated transmission and long-term potentiation².

Control Product

CNIH2/3 (extracellular) Blocking Peptide (#BLP-GC047) is the original antigen used for immunization during Anti-CNIH2/3 (extracellular) Antibody (#AGC-047) generation. The blocking peptide binds and ‘blocks’ Anti-CNIH2/3 (extracellular) primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.
