- Mouse
- Antibody Type
- Recombinant
- Immunogen
- Expression vector encoding full length mouse ARTC2.
- Formulation
- 1 mg/mL S+16a Nanobody in PBS. Purity ≥ 95%, as determined by Coomassie stained SDS-PAGE. Less than 0.01 ng of endotoxin/?g of protein, as determined by the LAL method.
- Preparation
- Treg-Protector ? is sterilized by filtration through a 0.22 ?m membrane and contains no preservatives.
- Concentration
- 1.0 mg/ml
- Storage & Handling
- Store between 2°C and 8°C. Do not freeze. Keep sterile.
- Application
-
Block - Quality tested
- Recommended Usage
We recommend diluting Treg-Protector? 1:4 with sterile PBS and administer 200 ?L (50 ?g) 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.
