Product Details

Verified Reactivity
Human
Reported Reactivity
African Green, Baboon, Cynomolgus, Rhesus
Antibody Type
Monoclonal
Host Species
Mouse
Immunogen
Full length human PD-L1
Formulation
0.2 ?m filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is <0.01 EU/?g of the protein (<0.001 ng/?g of the protein) as determined by the LAL test.
Preparation
The Ultra-LEAF? (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
Concentration
The antibody is bottled at the concentration indicated on the vial, typically between 2 mg/mL and 3 mg/mL. Older lots may have also been bottled at 1 mg/mL. To obtain lot-specific concentration, please enter the lot number in our Concentration and Expiration Lookup or Certificate of Analysis online tools.
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C. This Ultra-LEAF? solution contains no preservative; handle under aseptic conditions.
Application

FC - Quality tested
IHC, Block - Reported in the literature, not verified in house

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤2.0 ?g per million cells in 100 ?l volume or 100 ?l of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Clone 29E.2A3 is reported to recognize an epitope on PD-L1 within the PD-L1-CD80 binding region5.?Additional reported applications (for the relevant formats) include: blocking1-3 and immunohistochemical staining of acetone-fixed frozen sections1.?The Ultra-LEAF? purified antibody (Endotoxin < 0.01 EU/?g, Azide-Free, 0.2 ?m filtered) is recommended for functional assays (Cat. No. 329715, 329716, 329745 - 329748).?

It has been observed that clone 29E.2A3 is able to bind to Alexa Fluor? 700 antibody conjugates during multi-color immunofluorescent staining. This interaction can be resolved by sequentially staining with the 29E.2A3 antibody first and then followed by the?Alexa Fluor? 700?conjugate of interest.

Clone 29E.2A3 does not work in Western blot applications7.

Antigen Details

Distribution

T cells, B cells, NK cells, monocytes/macrophages, granulocytes and dendritic cells

Function
CD274 is involved in the costimulatory signal, essential for T lymphocyte proliferation and production of IL-10 and IFN-γ, in an IL-2-dependent and a PD-1-CD1-independent manner. Its interaction with PD-1-CD1 inhibits T-cell proliferation and cytokine production.
Ligand/Receptor
PD-1 (PDCD1)
Cell Type
B cells, Dendritic cells, Fibroblasts, Granulocytes, Macrophages, Monocytes, NK cells, T cells
Biology Area
Cancer Biomarkers, Costimulatory Molecules, Immunology
Molecular Family
Adhesion Molecules, CD Molecules, Immune Checkpoint Receptors
