  • RelevancemCLCA3 (alias gob-5) is the third murine member of the family of calcium-activated chloride channels (CLCA-family). mCLCA3 plays a role in diseases with secretory dysfunctions, including asthma and cystic fibrosis. The mCLCA3 protein is located in mucin granule membranes of goblet cells of the intestinal, respiratory and reproductive tracts. It is also secreted into the mucin layer on mucosal membranes. The protein appears to be involved in the synthesis, condensation or secretion of mucins.

  • Formalin-fixed, paraffin-embedded mouse colon tissue sections stained with anti-CLCA3 ab46512 used at 1/8000 dilution.
  • Anti-CLCA3 antibody (ab46512) at 1/500 dilution + MEF1 (Mouse embryonic fibroblast cell line) Whole Cell Lysate at 10 µg

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 100 kDa
    Observed band size : 35 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 16 kDa,95 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 1 minute
    CLCA3 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
  • ICC/IF image of ab46512 stained MEF1 cells. The cells were 4% PFA fixed (10mins) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab46512, 1/200 dilution) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you very much for your interest in ab46512.  To our knowledge, ab46512 has not been tested in frozen tissue sections (IHC-Fr).  There is no reason that I can see that it wouldn't work, but since we haven't tested it in IHC-Fr we wouldn't be a...
