Applications
Show applications key
Our Abpromise guarantee covers the use of ab70415 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
ICC/IF: Use a concentration of 10 µg/ml
IHC-P: Use a concentration of 5 µg/mlPerform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB: 1/500 - 1/1000.Detects a band of approximately 57 kDa (predicted molecular weight: 57 kDa).
Target
Function
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, functions as a chaperone that inhibits aggregation of misfolded proteins. 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 a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP.
Sequence similarities
Belongs to the protein disulfide isomerase family.
Contains 2 thioredoxin domains.
Cellular localization
Endoplasmic reticulum lumen. Melanosome. Cell membrane. Highly abundant. In some cell types, seems to be also secreted or associated with the plasma membrane, where it undergoes constant shedding and replacement from intracellular sources (Probable). Localizes near CD4-enriched regions on lymphoid cell surfaces. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

Immunocytochemistry/ Immunofluorescence - P4HB antibody (ab70415)
ab70415 at 10µg/ml staining P4HB in Hela cells by Immunocytochemistry/Immunofluorescence.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)-P4HB antibody(ab70415)
IHC image of ab70415 staining in human normal liver formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab70415, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
