Arginine-to-Ornithine ratio ELISA pack – Serum, Plasma – ISE-0410RArginine‑to‑Ornithine ELISA pack box with two 96‑well plates
The arginase inhibitor INCB-1158 restores Arg level while limiting Orn production in sera of MC38-tumor bearing mouse modelC57BL/6J mice were subcutaneously inoculated with MC38 colorectal cancer cell line and treated orally with 100mg/kg of INCB-1158 for one or five consecutive days. Sera were collected after each treatment period and subjected to Arg and Orn level quantification using #IS-I-0400R and #IS-I-1000R ELISA kits, respectively. Orn to Arg ratio was then calculated as a surrogate of Arginase activity.

Frequently asked questions
What does the Arginine / Ornithine ELISA pack measure?
It quantifies the concentrations of L‑Arginine and L‑Ornithine in serum or plasma so you can calculate the Arginine‑to‑Ornithine ratio, a key indicator of arginase activity and immune regulation.
How much sample do I need per analyte?
Only 20 µL of serum or plasma per well are required, making the kit suitable for studies with limited sample volume.
What are the detection limits?
The kits’ limits of detection are 2.1 µM for Arginine and 8.5 µM for Ornithine.
Which species are compatible?
The ELISA kits are compatible with any species (L-Arginine and L-Ornitine are conserved across species).
How long does the assay take?
Expect about 3 hours for sample preparation, followed by an overnight incubation. Color development and plate reading add roughly 1 hour the next day.
Is the kit CE‑IVD certified?
No. It is supplied for Research Use Only (RUO) and is not intended for diagnostic procedures.
Arginine-to-Ornithine ratio ELISA pack
With the Arginine‑to‑Ornithine Ratio ELISA Pack, quantify L‑Arginine and L‑Ornithine from just 20 µL of serum or plasma (any species) in one overnight assay, delivering fast, accurate insight into arginine‑pathway activity and immune regulation without relying on LC‑MS.
