    ab22595 was shown to specifically react with empty when empty knockout samples were used. Wild-type and empty knockout samples were subjected to SDS-PAGE. Ab22595 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

  • ab22595 staining Calnexin in wild-type HAP1 cells (top panel) and CANX knockout HAP1 cells (bottom panel). The cells were fixed with 4% formaldehyde (10min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab22595 at 1μg/ml and ab195889 at 1/250 dilution (shown in pseudocolour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

  • Kidney cortex using ab22595 shows clear cytoplasmic staining patterns. The visceral cells of the Glomerular tuft ( podocytes ) are strongly stained (indicated by red arrowheads). Distal convoluted tubular cells are generally moderately positive (with exceptions that are strongly positive). However, most of the cells that line the Proximal Convoluted Tubules (indicated by green arrowheads) are strongly positive.

    Predicted band size : 90 kDa
    Observed band size : 75 kDa (why is the actual band size different from the predicted?)

    Recent batches of ab22595 (AP217379 and AP151845) detect a band of ~ 75 kDa in Hela, U2OS and MCF-7 lysates. This band is completely blocked by the immunizing peptide so we believe this represents Calnexin. Moreoever, a band of the same size is detected by other Calnexin antibodies tested.

  • Calnexin - ER membrane marker was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to Calnexin - ER membrane marker and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab22595.
    Secondary: Goat polyclonal to mouse IgG light chain specific (HRP) at 1/5000 dilution.
    Band: 80kDa: Calnexin - ER membrane marker.
