General description

Endoplasmic reticulum resident protein 57 (ERp57) is also called Protein disulfide-isomerase A3 (PDIA3), 58 kDa glucose-regulated protein (GRP58), 58 kDa microsomal protein (p58), Disulfide isomerase ER-60, and Endoplasmic reticulum resident protein 60 (ERp60). ERp57 catalyzes the rearrangement of -S-S- bonds in proteins and is associated with signal transduction, nuclear protein import and apoptosis. ERp57 is expressed in the flagellum and head regions of spermatozoa.

Immunogen

Recombinant protein corresponding to human ERp57.

Application

Chromatin Immunoprecipitation Analysis: A representative lot from an independent laboratory lot detected ERp57 in M14 cell lysates (Chichiarelli, S., et al. (2010). Arch Biochem Biophys. 494(2):178-183; Chichiarelli, S., et al. (2007). J Cell Physiol. 210(2):343-351.).

Western Blotting Analysis: A 1:2,000 dilution from a representative lot detected ERp57 in NPA, WRO, ARO and NCI cell lysates (Prof. F. Altieri, University of Rome, La Sapienza).
Detect ERp57 using this rabbit polyclonal antibody, Anti-ERp57 Antibody validated for use in western blotting & Chromatin IP (ChIP).
Research Category
Epigenetics & Nuclear Function
Research Sub Category
Transcription Factors

Quality

Evaluated by Western Blotting in HeLa cell lysate.

Western Blotting Analysis: 1:1,000 dilution of this antibody detected ERp57 in 10 µg of HeLa cell lysate.

Target description

~57 kDa observed

Physical form

Rabbit polyclonal in buffer containing serum with 0.05% sodium azide.
Unpurified

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

The protein ERp57/GRP58 is a member of the protein disulfide isomerase family and is also a glucose-regulated protein, which, together with the other GRPs, is induced by a variety of cellular stress conditions. ERp57/GRP58 is mainly located in the endoplasmic

Chromatin immunoprecipitation in M14 melanoma cells showed that the protein ERp57 (endoplasmic reticulum protein 57) binds to DNA in the proximity of STAT3 in a subset of STAT3-regulated genes. In the same cells, IL-6 induced a significant increase of the
