Cat. No. 221 111	100 µg purified IgG, lyophilized. Azide was added before lyophilization. For reconstitution add 100 µl H₂O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications	WB: not recommended IP: not tested yet ICC: not tested yet IHC: not tested yet IHC-P: not tested yet FACS: yes Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section. Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section. Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section. Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section. Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Fluorescence-activated cell sorting (FACS); usually cells are fluorescently labeled with antibodies against cell-surface antigens followed by cell-sorter analysis.

Background

Regulatory T-cells (T_reg-cells) are involved in the homeostasis of immune reactions and tolerance. These specialized T-cells suppress auto-reactive cells and inhibit autoimmunity. Development and function of T_reg-cells depend on the expression of the transcription factor FOX3P.
The orphan receptor GARP, also referred to as LRRC 32, is exclusively found on T_reg-cells upon stimulation with anti-CD3/IL-2 or anti-CD3/anti-CD28/IL-2. Additionally it has been shown, that ectopic GARP expression strongly induces FOXP3.
