Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD44 antibody [Hermes-3] (AB254530)

Immunohistochemical analysis of paraffin-embedded human bladder carcinoma tissue labeling CD44 with ab254530 at 0.107μg/ml, followed by ready to use secondary. Membranous staining on human bladder carcinoma is observed. The section was incubated with ab254530 for 5 mins at RT. The immunostaining staining was performed on a Leica Biosystems BOND^® RX instrument. Counterstained with hematoxylin.
Secondary antibody only control : Used PBS instead of primary antibody, followed by ready to use secondary.

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins.

Immunocytochemistry/ Immunofluorescence - Anti-CD44 antibody [Hermes-3] (AB254530)

ab254530 staining CD44 in wild-type HeLa cells (top panel) and CD44 knockout HeLa cells (ab262515)(bottom panel). The cells were fixed with 100% methanol (5 min) then permeabilized with 0.1% Tween 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 ab254530 at 0.4μg/ml concentration and ab6046 (Rabbit polyclonal to beta Tubulin) at 1/1000 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat secondary antibody to mouse IgG (Alexa Fluor^® 488) (ab150117) at 2 μg/ml (shown in green) and a goat secondary antibody to rabbit IgG (Alexa Fluor^® 594) (ab150080) at 2 μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems TCS SP8).

Immunocytochemistry/ Immunofluorescence - Anti-CD44 antibody [Hermes-3] (AB254530)

ab254530 was shown to react with CD44 in wild-type HAP1 cells in Immunocytochemistry with loss of signal observed in a CD44 knockout cell line. Wild-type and knockout cells were mixed and pelleted at a 1 : 1 ratio on coverslips. The cells were fixed with 4% paraformaldehyde (15 min) then permeabilized with 0.1% Triton X-100 (10min) and then blocked. The cells were then incubated with ab254530 at 1/500 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a secondary antibody to (Alexa Fluor^® 555) at 0.5 μg/ml. Acquisition of the green (wild-type), red (antibody staining) and far-red (knockout) channels was performed. Representative grayscale images of the red channel are shown. Wild-type and knockout cells are outlined with yellow and magenta dashed line, respectively. Schematic representation of the mosaic strategy used is shown on the bottom-right panel. Image was acquired with a Zeiss(LSM-880). These data were provided by YCharOS Inc., an open science company with the mission of characterizing commercially available antibody reagents for all human proteins.

Western blot - Anti-CD44 antibody [Hermes-3] (AB254530)

ab254530 was shown to react with CD44 in wild-type HAP1 cells in Western blot with loss of signal observed in a CD44 knockout cell line. Wild-type HAP1 and CD44 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab254530 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with goat anti-mouse HRP secondary antibodies at 0.3ug/mL before imaging.
