• Reactivity: Human
• Specificity: This assay has high sensitivity and excellent specificity for detection of Programmed Cell Death Protein 1 Ligand 1 (PDL1).; No significant cross-reactivity or interference between Programmed Cell Death Protein 1 Ligand 1 (PDL1) and analogues was observed.
• Sequence Length: 176

• Applicable Applications for PDL1 clia kit: Chemiluminescence Immunoassay (CLIA)
• Assay Type: Double-antibody Sandwich
• Samples: Serum, plasma, tissue homogenates and other biological fluids
• Detection Range: 27.4-20,000pg/mL
• Sensitivity: The minimum detectable dose of this kit is typically less than 11.5pg/mL
• Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Programmed Cell Death Protein 1 Ligand 1 (PDL1) were tested 20 times on one plate, respectively.; Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Programmed Cell Death Protein 1 Ligand 1 (PDL1) were tested on 3 different plates, 8 replicates in each plate.; CV(%) = SD/meanX100; Intra-Assay: CV<10%; Inter-Assay: CV<12%
• Test Principle: The microplate provided in this kit has been pre-coated with an antibody specific to Programmed Cell Death Protein 1 Ligand 1 (PDL1). Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Programmed Cell Death Protein 1 Ligand 1 (PDL1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Programmed Cell Death Protein 1 Ligand 1 (PDL1) level in the sample or standard.
• Preparation and Storage: The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.; To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

NCBI Description

This gene encodes an immune inhibitory receptor ligand that is expressed by hematopoietic and non-hematopoietic cells, such as T cells and B cells and various types of tumor cells. The encoded protein is a type I transmembrane protein that has immunoglobulin V-like and C-like domains. Interaction of this ligand with its receptor inhibits T-cell activation and cytokine production. During infection or inflammation of normal tissue, this interaction is important for preventing autoimmunity by maintaining homeostasis of the immune response. In tumor microenvironments, this interaction provides an immune escape for tumor cells through cytotoxic T-cell inactivation. Expression of this gene in tumor cells is considered to be prognostic in many types of human malignancies, including colon cancer and renal cell carcinoma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

Uniprot Description

CD274: 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. Belongs to the immunoglobulin superfamily. BTN/MOG family. 3 isoforms of the human protein are produced by alternative splicing.
