Datasheets
  • secretin Antibody (E-9) is a mouse monoclonal IgG1 κ secretin antibody provided at 200 µg/ml
  • raised against amino acids 33-121 mapping within an N-terminal extracellular domain of secretin of human origin
  • secretin Antibody (E-9) is recommended for detection of secretin of human origin by WB, IP, IF and ELISA

    secretin Antibody (E-9) is an IgG1 κ mouse monoclonal secretin antibody (also designated secretin antibody) that detects the secretin protein of human origin by WB, IP, IF and ELISA. secretin Antibody (E-9) is available as both the non-conjugated anti-secretin receptor antibody form, as well as multiple conjugated forms of anti-secretin receptor antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Secretin is a 27-amino acid hormone produced by specific endocrine cells, S cells, located in the mucosa of the proximal small intestine. Secretin is known to be a potent stimulus for the secretion of bicarbonate-rich pancreatic juice. Secretion of secretin is stimulated by the presence of either acidic pH or fatty acids in the duodenum. Secretin is synthesized as a larger precursor. The deduced amino acid sequence includes a signal peptide, an amino-terminal peptide, secretin itself, and a 72-amino acid carboxy-terminal peptide. Secretin stimulates ductal bile secretion by directly interacting with cholangiocytes. It stimulates exocytosis in cholangiocytes, which transport water mainly via the water channel aquaporin-1. Secretin deficiency may be implicated in autistic syndrome, suggesting that the hormone could have a neuroendocrine function in addition to its role in digestion. The gene which encodes secretin maps to human chromosome 11p15.5.

    The data sheet says this antibody was raised against amino acids 33-121 mapping at the C-terminus of secretin of human origin. Secretin receptor (P47872) is a 440 aa protein. Where is the epitope? At the N-terminus?

    Is is directed against the receptor or secretin itself? The datasheet does not give clear answers.

    Asked by: Loudi
    Thank you for your question. Anti-secretin receptor Antibody (E-9): sc-166112 recognizes secretin receptor, with protein accession number P47872.

    Is there any secretin antibody available specific for mouse/rat.If available can we inject this antibody by intra peritoneally/i.v./ in vivo in animal to check its binding to secretin receptor in vivo?

    Asked by: vijay modak
    Thank you for your question. At this time we have not validated any of our secretin receptor antibodies for reactivity with mouse or rat. We do not support any of our products for use in vivo or in live animal studies.

    For Western Blot, is it recommended to use denatured or non-denatured conditions with secretin receptor (E-9): sc-166112 monoclonal antibody?

    Asked by: jenniferc
    Thank you for your question. We recommend this antibody for use in denatured Western Blot conditions. It has not been validated for use in non-denatured conditions. Please contact our Technical Service Department for further details or inquiries.
