Description (continued) Current methods used to measure the activity of anti-PD-1 or anti-PD-L1 biologics rely on primary human T cells and For the PD1/PDL1 inhibitors, based on what I read the statistics seems to look like this: 20% partial an complete results, 40% stable diseas, 40% no response. This assay can be used to screen for small molecules that inhibit binding, as a competitive ligand binding (CLB) assay to screen therapeutic blocking antibodies, and for potency assays. While studies have shown that PD-1–PD-L interaction is important to maintain a balance between peripheral tolerance and autoimmunity, it also impairs viral and tumor immunity, promoting chronic infection and tumor progression. About This Kit. However, this is a statistics over all cancer types and depending on the cancer type the partial and complete response may be much higher such as for melanoma, bladder, RCC, etc. PD1 expression has been observed in a variety of cancers including melanoma and non-small cell lung cancer. The assay will exclusively recognize both natural and recombinant H PD-1. To limit damage to surrounding tissue, normal cells differentiate themselves by expressing a protein signal called PD-L1 (programmed death ligand 1).

With this kit, only three simple steps on a microtiter plate are required. The PD1:PDL1 pathway is an essential negative costimulatory pathway that plays a key role in regulating the alloimune response. PD-1 was initially considered to be a molecule that regulates cell death but is now identified as a key immune checkpoint inhibitory receptor. PD-L1 is a protein that allows some cells to escape an attack by the immune system. The PD-1 (programmed cell death-1) receptor is expressed on the surface of activated T cells. Utilizing HTRF (Homogeneous Time-resolved Fluorescence) technology, the assay enables simple and rapid characterization of compound and antibody blockers in a high throughput format.

The programmed cell death protein 1 receptor (PD-1) receptor was first described in the early 1990s given its expression during induction of apoptosis in a T-cell hybridoma [1, 2].Since its initial discovery several groups have identified that engagement of PD-1 through its ligand, programmed death ligand 1 (PD-L1), negatively regulates T-cell-mediated immune responses [3,4,5,6]. • Characterize the biological activity of PD-1 and its interactions with ligands.
