• Isotype: IgG2ak
• Clone Number: ANC8C9
• Purity/Purification: Purified (with Antibiotics)
• Form/Format: 50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 0.5% Gentamicin sulfate
• Concentration: 1.0 mg/ml (varies by lot)
• Sequence Length: 662

• Applicable Applications for anti-GARP antibody: Flow Cytometry (FC/FACS), ELISA (EIA)
• Performance: (FACS analysis) Ficoll prepared human PBMC were stimulated in culture overnight with immobilized anti-human CD3 antibody, anti-human CD28 mAb, and human IL-2. Cells were harvested and 5 x 105 cells per tube were washed and pre incubated ~5 minutes with 20 ul human IgG at 250 ug/ml (to block non specific binding) after which they were incubated 45 minutes on ice with 80 ul of anti-CD4/APC conjugate and anti-human GARP/Biotin at a concentration of 5 ug/ml. Cells were washed twice and incubated with 50 ul of 2 degree reagent Streptavidin/PE, after which they were washed three times, fixed and analyzed by FACS, gating on CD4 positive lymphoid cells. A net 4.7 % sub population of gated cells stained positive with a mean shift of 1.59 log10 fluorescent units when compared to a Mouse IgG2a/Biotin isotype control. This binding was blocked when cells were pre incubated with 50 ug/ml unlabeled anti-human GARP mAb.
• Production: Antibody was Protein A purified from (low FBS containing) tissue culture supernatant. Purity was >95% Immunoglobulin by SDS-PAGE with less than 1% Bovine Immunoglobulin.
• Buffer: 50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 0.5 mg/ml Gentamicin Sulfate (as a preservative).
• Group Header: anti-human GARP (LRRC32)
• Immunogen: Recombinant human GARP
• Preparation and Storage: Store at 2 - 5 degree C. Freeze/Thawing is not recommended.; Product should retain activity for at least 12 months after shipping date when stored as recommended.

Related Product Information for anti-GARP antibody

Information: Human GARP (Glycoprotein A Repetitions Predominant/ Leucine Rich Repeat Containing 32) is a roughly 80 kd transmembrane cell surface molecule expressed on a variety of tissue types, including a subset of activated T regulatory cells. GARP covalently binds latent TGF-beta 1 serving as a regulatory reservoir(1). Antibody ANC8C9 binds to recombinant GARP in EIA and to cell surface GARP expressed on a subset of FOXP3 positive cells.
