Our Abpromise guarantee covers the use of ab40145 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Blocking - Blocking peptide for Anti-FAK (phospho Y397) antibody (ab39967)
- First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions.
- If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer.
- Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent.
- Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised.
- Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.
Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.

To demonstrate the specificity of the phosphorylation site specific antibody (ab4803) a 1/150 dilution of anti human-FAK (phospho Y397) antibody was pre-incubated with 200 fold molar excess of peptide (ab40145, 1/15 dilution) for 12 hours rolling at 4°C.
Human Tissue sections (kidney) were deparaffinized, rehydrated and antigen retrieval was performed using citrate buffer pH 6.0. Endogenous peroxidase was quenched using 3% hydrogenperoxide in methanol and blocking was performed. Primary antibody alone (positive control) or mixed with peptide (blocking control) or antibody diluent alone (negative control) was applied to tissue sections and incubated for 16 hours at 4°C. Detection was performed using a HRP detection system. Nuclei were counterstained using Hematoxylin.
