PurityImmunogen affinity purified
Purification notesPurified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated paxillin. The final product is generated by affinity chromatography using a paxillin-derived peptide that is phosphorylated at serine 126.
Our Abpromise guarantee covers the use of ab24402 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000. Detects a band of approximately 68 kDa.|
FunctionCytoskeletal protein involved in actin-membrane attachment at sites of cell adhesion to the extracellular matrix (focal adhesion).
Sequence similaritiesBelongs to the paxillin family.
Contains 4 LIM zinc-binding domains.
modificationsPhosphorylated on tyrosine residues during integrin-mediated cell adhesion, embryonic development, fibroblast transformation and following stimulation of cells by mitogens.
Cellular localizationCytoplasm > cytoskeleton. Cell junction > focal adhesion.

Observed band size: 68 kDa why is the actual band size different from the predicted?
Lysates were resolved on a 10% polyacrylamide gel and transferred to PVDF. The membrane was blocked with a 5% milk-TBST buffer for one hour at room temperature, and then incubated with the Paxillin [pS126] antibody for two hours at room temperature in a 1% milk-TBST buffer, following its prior incubation with or without peptides. Following incubation with goat F(ab’)2 anti-rabbit IgG HRP conjugate and bands were detected using the Pierce SuperSignal method. The data show that only the phosphopeptide corresponding to Paxillin [pS 126 ] blocks the antibody signal, thereby demonstrating the specificity of the antibody. No competition was seen following incubation with paxillin phosphopeptides to S130, S178, S380, S455, or S479 (not shown). The antibody was also shown to be specific using 293 cells transfected with wild-type EGFP-tagged human paxillin treated with EGF (not shown).
