CD11b was immunoprecipitated using 0.5mg RAW 264.7 whole cell extract, 5µg of Rabbit polyclonal to CD11b 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, RAW 264.7 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 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab128797.Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).Band: 170kDa, non specific bands - 42, 55 and 65kDa: We are unsure as to the identity of this extra band; CD11b
Overlay histogram showing RAW 264.7 cells stained with ab128797 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab128797, 0.1μg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (polyclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

ICC/IF image of ab128797 stained Raw246.7 cells. The cells were 4% paraformaldehyde 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 (ab128797, 1µg/ml) 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. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
