Product Name :
QPCT polyclonal antibody Background :
QPCT (glutaminyl-peptide cyclotransferase) is a 361 amino acid protein that belongs to the glutaminyl-peptide cyclotransferase family. QPCT is responsible for the presence of pyroglutamyl residues in many neuroendocrine peptides. QPCT binds one zinc ion per subunit and has a bias against acidic and tryptophan residues adjacent to the N-terminal glutaminyl residue. The human QPCT gene shares 86% overall sequence identity with the bovine homolog. QPCT contains an N-terminal signal peptide region, several glycosylation and phosphorylation sites and two cysteine residues conserved between the bovine and human enzymes. Existing as two alternatively spliced isoforms, the QPCT gene is conserved in chimpanzee, dog, cow, mouse, rat, chicken, fruit fly, mosquito, M.grisea and N.crassa, and maps to human chromosome 2p22.2. Product :
Rabbit IgG, 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2 Storage&Stability :

Tips:
For phospho antibody, we provide phospho peptide（0.5mg) and non-phospho peptide(0.5mg).Describe :
Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (WB) and Immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or IHC performed with the neutralized antibody.Formula:
Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 10 mg/ml.The purity is >90%,tested by HPLC and MS.
Storage:
The freeze-dried powder is more stable. For short time at 2-8°C. For long term storage store at -20°C.
