Ab47742 staining human normal temporal lobe. Staining is localized to the cytoplasm.
Left panel: with primary antibody at 1 ug/ml. Right panel: isotype control.
Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS), then incubated with primary antibody for 20 minutes, and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Anti-SerpinB2/PAI-2 antibody (ab47742) at 1 µg/ml + Human placenta tissue lysate - total protein (ab29745) at 10 µg

Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

Developed using the ECL technique.

Performed under reducing conditions.

Predicted band size: 46 kDa
Observed band size: 49 kDa why is the actual band size different from the predicted?
Additional bands at: 72 kDa. We are unsure as to the identity of these extra bands.


Exposure time: 1 minute

SerpinB2/PAI-2 contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
