ab54208 at 1/1000 dilution staining CD34 in human spleen tissue sections by Immunohistochemistry (Formalin/ PFA-fixed paraffin-embedded tissue sections). The DAB staining procedure was used for tissue section staining.

Overlay histogram showing Jurkat cells stained with ab54208 (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 (ab54208, 1μg/1x10⁶ cells) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H+L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG ( 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.

Anti-CD34 antibody [9B10D4/4H5E7] (ab54208) at 1/200 dilution + Truncated CD34 recombinant protein

Predicted band size: 41 kDa
Observed band size: 35 kDa why is the actual band size different from the predicted?
