ARTC2, also known as ART2.2, is a 35 kD, GPI-anchored, and cell surface ADP-ribosyltransferase that is highly expressed by regulatory T cells (Tregs) and natural killer T (NKT) cells. ARTC2 is enzymatically active at 4°C. Through the ribosylation of the ion channel P2X7, ARTC2 mediates NAD+-induced cell death (NICD) and the proteolytic shedding of CD27 and CD62L. Blocking the activity ARTC2 with Treg-Protector™ improves the recovery of Tregs and NKT cells during their isolation from lymphatic and peripheral tissues.

- Application
-
Block - Quality tested
- Recommended Usage
-
We recommend diluting Treg-Protector™ 1:4 with sterile PBS and administer 200 µL (50 µg) intravenously (i.v.) of diluted Treg-Protector™ per mouse. Euthanize the mouse and begin the cell preparation 15 - 60 minutes after the injection. Intraperitoneal (IP) injection is also effective at similar doses (validated by developer).
- Application Notes
-
Treg-Protector™ (S+16a Nanobody) is a recombinant llama VH Ig domain that binds to the ADP-ribosyltransferase ARTC2, which reversibly blocks its enzymatic activity and protects ARTC2+ cells from NAD+-induced cell death (NICD), which is caused by the release of NAD+ by cells that die during the preparation of primary lymphocytes. The S+16a nanobody has been demonstrated to protect a variety of cell types including Tregs, NKT cells, and tissue-resident memory T cells8.
