Area of research
You can block the antibody by the specific target amino acid sequence of peptide.
Form & Buffer
Provided in phosphate buffered saline (PBS), pH 7.2, containing 0.1% BSA and 0.02% thimerosal.
Store at -20 deg C for short term storage. Aliquot and store at -70 deg c for long term storage, avoid repeated freeze/thaw cycles.
The peptide is used for blocking the binding of Smad4 antibody (catalog no. 20R-1588). In optimal conditions, it blocks the binding completely in Western blot analysis by incubating the peptide with equal volume of antibody for 30 minutes at 37 deg C.
Peptides short amino acid chains or epitopes or blocking antagonists. The shortest peptides are dipeptides, consisting of 2 amino acids joined by a single peptide bond, followed by tripeptides, tetra peptides, ... till polypeptides that are long, continuous, and unbranched synthetic peptide chains. These biological oligomers and polymers can be Solid-phase peptide synthesis (SPPS), or in continue produced for custom peptide synthesis projects. The High-efficiency solid phase peptide synthesis (HE-SPPS) is give very low production costs.
