CD279 is a 50-55 kD immunoglobulin superfamily member, also known as programmed death-1 (PD-1). PD-1 is expressed on a subset of CD4-CD8- thymocytes, and on activated T and B cells. PD-1 is thought to be involved in lymphocyte clonal selection and peripheral tolerance. The PD-1 ligands, PD-L1 (also known as B7-H1) and PD-L2 (B7-DC), are members of the B7 immunoglobulin superfamily. The RMP1-14 antibody has been reported to block the binding of PD-1 to its ligands (B7-H1 and B7-DC) and to inhibit T cell proliferation and cytokine production costimulated by macrophages (but not by dendritic cells and B cells).Product Details
- Antibody Type
- Host Species
- Mouse PD-1 transfected BHK cells
- 0.2 µm filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is <0.01 EU/µg of the protein (<0.001 ng/µg of the protein) as determined by the LAL test.
- The Ultra-LEAF™ (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
- 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. Please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.
- 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.
FC - Quality tested
IHC, WB, FA - 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 ≤1.0 µg per million cells in 100 µl volume or 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
Additional reported applications (for relevant formats of this clone) include: immunohistochemical staining of acetone-fixed frozen sections1, Western blotting2,6, inhibition of macrophages (but not B cells and dendritic cells) costimulated T cell proliferation3,5, and blocking the binding of PD-1 to B7-H1 or B7-DC3,4,8. The LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 114108). For highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 114110) with a lower endotoxin limit than standard LEAF™ purified antibodies.

- Do you guarantee that your antibodies are totally pathogen free?
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
