Target

  • Function

    Calcium-binding protein that interacts with newly synthesized glycoproteins in the endoplasmic reticulum. It may act in assisting protein assembly and/or in the retention within the ER of unassembled protein subunits. It seems to play a major role in the quality control apparatus of the ER by the retention of incorrectly folded proteins.

  • Sequence similarities

    Belongs to the calreticulin family.

  • Cellular localization

    Endoplasmic reticulum membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
  • Information by UniProt

  • Database links

    • Alternative names

      Predicted band size: 68 kDa



      ab195198 was shown to recognize Calnexin in wild-type HAP1 cells as signal was lost at the expected MW in CANX (Calnexin) knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and CANX (Calnexin) knockout samples were subjected to SDS-PAGE. Ab195198 and ab184095 (Mouse monoclonal [mAbcam 9484] to GAPDH - Loading Control (Alexa Fluor® 680) loading control) were incubated overnight at 4°C at 1/5000 dilution and 1/1000 dilution respectively. The loading control was imaged using the Licor Odyssey CLx prior to blots being developed with ECL technique.

      Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-Calnexin antibody [EPR3633(2)] - ER Membrane Marker (ab195198)

      IHC image of Calnexin staining in a section of formalin-fixed paraffin-embedded normal human colon tissue*, performed on a Leica BOND. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab195198 at 1/500 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.

      For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

      Exposure time: 20 minutes


      This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab195198 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.
