Product Summary for Insulin Antibody (E2-E3 (same as INS04))

Immunogen

Purified pig insulin, conjugated to KLH (Uniprot: P01308)

Localization

Cytoplasmic

Specificity

Recognizes a polypeptide which is identified as insulin, a 51-amino acid polypeptide composed of A and B chains connected through the C-peptide. Proinsulin, which has very little biological activity, is cleaved by proteases within its cell of origin into the insulin molecule and the C-terminal basic residue. Insulin enhances membrane transport of glucose, amino acids, and certain ions. It also promotes glycogen storage, formation of triglycerides, and synthesis of proteins and nucleic acids. Deficiency of insulin results in diabetes mellitus. The main storage site for insulin is the pancreatic islets. Antibodies to insulin are important as beta-cell and insulinoma marker.

Scientific Data Images for Insulin Antibody (E2-E3 (same as INS04))

Western Blot: Insulin Antibody (E2-E3 (same as INS04)) [NBP2-34260] - Probing of Western blots of pancreatic lysates from control and iron overloaded Tg40 PrP and PrP-/- mice with antibodies specific for insulin dimer and pentamer (upper and lower panels) shows decreased expression in Tg40 PrP relative to PrP-/- samples (lanes 1 & 5 vs. 3 & 7). Image collected and cropped by CiteAb from the following publication (nature.com/articles/s41598-018-24786-1), licensed under a CC-BY license.
Immunohistochemistry: Insulin Antibody (E2-E3 (same as INS04)) [NBP2-34260] - Immunohistochemistry of pancreas shows relatively higher reactivity for insulin in PrP-/- relative to Tg40 PrP sections (panels 1 & 3). Iron overloading decreases insulin reactivity in Tg40 PrP but not in PrP-/- samples (panels 1 vs. 2 & 3 vs. 4). Reaction for glucagon is higher in iron overloaded Tg40 PrP relative to control samples (panels 5 & 6). The difference is minimal in PrP-/- samples (panels 7 & 8).

Immunohistochemistry-Paraffin: Insulin Antibody (E2-E3 (same as INS04)) [NBP2-34260] - Formalin-fixed, paraffin-embedded human pancreas stained with insulin Monoclonal Antibody (E2-E3)

Applications for Insulin Antibody (E2-E3 (same as INS04))

Application
Recommended Usage

Immunohistochemistry-Paraffin

1-2 ug/ml

Western Blot

0.5-1ug/ml
Application Notes
Immunohistochemistry (Formalin-fixed): 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes.
Optimal dilution for a specific application should be determined.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: Insulin

After removal of the precursor signal peptide, proinsulin is post-translationally cleaved into two chains (peptide A and peptide B) that are covalently linked via two disulfide bonds. Binding of this mature form of insulin to the insulin receptor (INSR) stimulates glucose uptake. A variety of mutant alleles with changes in the coding region have been identified. There is a read-through gene, INS-IGF2, which overlaps with this gene at the 5' region and with the IGF2 gene at the 3' region. (provided by RefSeq)
