Product details

Protein Disulfide Isomerase/P4HB ELISA Kit- Extracellular (ab324924) is a rapid single-wash sandwich 90-min ELISA to measure Protein Disulfide Isomerase/P4HB in Serum, Citrate Plasma, EDTA Plasma, Heparin Plasma, Supernatant. This SimpleStep sensitivity is 50.82 pg/ml.

How the assay works

Protein Disulfide Isomerase/P4HB ELISA Kit- Extracellular (ab324924) SimpleStep ELISA® employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.

Assay Specificity

Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Target data

This multifunctional protein catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. May therefore cause structural modifications of exofacial proteins. Inside the cell, seems to form/rearrange disulfide bonds of nascent proteins. At high concentrations and following phosphorylation by FAM20C, functions as a chaperone that inhibits aggregation of misfolded proteins (PubMed : 32149426). At low concentrations, facilitates aggregation (anti-chaperone activity). May be involved with other chaperones in the structural modification of the TG precursor in hormone biogenesis. Also acts as a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP. Receptor for LGALS9; the interaction retains P4HB at the cell surface of Th2 T helper cells, increasing disulfide reductase activity at the plasma membrane, altering the plasma membrane redox state and enhancing cell migration (PubMed : 21670307).
