Product Overview
This rabbit polyclonal antibody detects peptidyl-prolyl cis-trans isomerase E (gene PPIE) in human and mouse samples and is validated for Western blot, ICC/IF, flow cytometry, immunoprecipitation and ELISA. The predicted molecular weight is 33.4 kDa, and the supplier reports an observed band at about 35 kDa.
Cyclophilin E (PPIE) is a nuclear peptidyl-prolyl isomerase with an RNA-recognition motif. It is a component of the spliceosome and takes part in pre-mRNA splicing, combining RNA binding with proline isomerase activity. It has also been reported to modulate the histone methyltransferase MLL1 (KMT2A).

Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places peptidyl-prolyl cis-trans isomerase E in the nucleus. Tissue expression noted by UniProt (human): Found in all the examined tissues including heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
