ICC/IF image of ab22595 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab22595, 5µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).

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.

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. See Abreview

ICC/IF image of ab22595 stained HeLa cells. The cells were 4% PFA fixed (10 min) 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 (ab22595, 5µg/ml) overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti-rabbit IgG - H&L, pre-adsorbed (ab96899) 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.
