Product overview
Monkey PD-L1 [28-8] ELISA kit (ab279408) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Monkey PD-L1 [28-8] protein in monkey serum, plasma and cell culture supernatant samples. It uses our proprietary SimpleStep ELISA® technology. Quantitate Monkey PD-L1 [28-8] with 15.85 pg/mL sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells stripsA 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Notes
PD-L1 (also known as CD274 or B7-H1) is a membrane bound glycoprotein involved in regulation of the immune system. PD-L1 is expressed on a variety of inflammatory-activated cells as well as some carcinomas and in melanoma. PD-L1 binds to PD-1 and CD80, where it can suppress T cell activation and proliferation as well as induce apoptosis. Levels of PD-L1 are increased in the plasma of cancer patients as well as in cerebrospinal fluid of gliomas. PD-L1 can bind PD-1 in order to regulate T cell apoptosis.

Function
Involved in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production. -
Tissue specificity
Highly expressed in the heart, skeletal muscle, placenta and lung. Weakly expressed in the thymus, spleen, kidney and liver. Expressed on activated T- and B-cells, dendritic cells, keratinocytes and monocytes. -
Sequence similarities
Belongs to the immunoglobulin superfamily. BTN/MOG family.
Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
Contains 1 Ig-like V-type (immunoglobulin-like) domain. -

SimpleStep ELISA Protocol Diagram
SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

Interpolated concentrations of native PD-L1 in cynomolgus serum and stimulated cynomolgus PBMC cell culture supernatant samples.PBMC cell culture supernatant samples were stimulated with 50 ng/ml PMA and 1 µg/ml ionomycin for 24 hours. The concentrations of PD-L1 were measured in duplicates, interpolated from the PD-L1 standard curves and corrected for sample dilution. Undiluted samples are as follows: cynomolgus serum 50% and stimulated cynomolgus PBMC cell culture supernatant 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean PD-L1 concentration was determined to be 2,281.25 pg/ml in cynomolgus serum and 2,546.31 pg/ml in stimulated cynomolgus PBMC cell culture supernatant.

Interpolated concentrations of native PD-L1 in rhesus plasma (heparin), rhesus plasma (EDTA), and stimulated rhesus PBMC cell culture supernatant samples.PBMC cell culture supernatant samples were stimulated with 50 ng/ml PMA and 1 µg/ml ionomycin for 24 hours. The concentrations of PD-L1 were measured in duplicates, interpolated from the PD-L1 standard curves and corrected for sample dilution. Undiluted samples are as follows: rhesus plasma (heparin) 50%, rhesus plasma (EDTA) 25%, and stimulated rhesus PBMC cell culture supernatant 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean PD-L1 concentration was determined to be 860.85 pg/ml in rhesus plasma (heparin), 3,398.46 pg/ml in rhesus plasma (EDTA), and 4,486.45 pg/ml in stimulated rhesus PBMC cell culture supernatant.
