The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Blocking - Blocking peptide for Anti-BCL9 antibody (ab37305)
- 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.

B-cell CLL/lymphoma 9
BCL9 is involved in signal transduction through the Wnt pathway. It promotes beta-catenin's transcriptional activity. BCL9 is associated with B-cell acute lymphoblastic leukemia. The overexpression of BCL9 may be of pathogenic significance in B-cell malignancies (referenced from swissprot and entrez gene).
