Background
Also known as: Endothelial protein C receptor, Activated protein C receptor, APC receptor, Centrocyclin, Centrosomal protein CCD41, Endothelial cell protein C receptor, CD201, Procr.
Mouse EPCR (Procr) is a commonly measured biological analyte that can provide insight into cellular state and tissue physiology. This target is frequently investigated in Molecular & Cellular Biology research contexts. This analyte is often discussed in the context of cell-surface signaling and cell-state markers. Many receptors and surface markers act as gateways for signaling or as phenotypic indicators of specific cell populations and activation states.
Biological context
In experimental systems, protein abundance can reflect regulated expression, secretion, processing, or clearance. Interpreting changes benefits from considering compartment (cell-associated vs soluble), the time scale of regulation, and whether complexes or modified forms contribute to the measured signal.
Why it matters in research
- Systems-level readout: Quantification supports comparisons across conditions, time points, and treatment groups.
- Mechanistic interpretation: Pairing with upstream regulators and downstream markers helps contextualize changes.
- Biomarker-style profiling: Measuring panels of related analytes can improve interpretability in complex models.

- Test tubes for dilution.
Activating reagent preparation
EPCR is mostly contained as inactive form in samples, please activate it before assay. Don't activate recombinant EPCR.
Solution A: 1N HCI: add 8.33ml of 12N HCI into 91.67ml of H2O.
Solution B: 1.2N NaOH/0.5M HEPES: add 12ml of 10N NaOH and 11.9g HEPES into 75ml of H2O, add H2O to adjust volume to 100ml.
Sample activation procedure
Activate the sample
Cell culture supernatants, serum and plasma (heparin, EDTA): add activating reagent pro rata, i.e. add 25μl of Solution A into 50μl of sample, 10 min later, add 25μl of Solution B. PH 7.0-7.6.
It is unnecessary to activate the recombinant EPCR.
Sample was diluted partly after adding activating reagent, so please pay attention to this when calculate target protein concentration.
