Preparation and Storage
推奨アッセイ手順
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

The 29F.1A12 monoclonal antibody specifically recognizes CD279 which is also known as Programmed Death-1 (PD-1). CD279 (PD-1) is a ~55-kDa type I transmembrane glycoprotein that is encoded by Pdcd1 (Programmed cell death 1) which belongs to the CD28/CTLA-4 family of immunoreceptors within the Ig superfamily. CD279 (PD-1) is comprised of an extracellular region with an IgV-like domain, a transmembrane sequence, and an intracellular region with an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM) that are associated with suppressive immunoregulatory functions. CD279 (PD-1) is variably expressed on some thymocyte subsets and developing B lymphocytes at the pro-B-cell stage. It is also inducibly expressed on activated myeloid cells, B cells, and T cells including exhausted T cells found in mice during chronic viral infections or cancer. Although this co-inhibitory receptor plays roles in mediating immunological tolerance and preventing autoimmune responses it can also inhibit protective immune responses against microbial infections and cancer. CD273 (also known as PD-L2 or B7-DC) and CD274 (PD-L1 or B7-H1) are members of the B7 family within the Ig superfamily. These molecules serve as ligands for CD279 (PD-1) and are variably expressed on lymphoid and nonlymphoid cell types including antigen-presenting cells and tumor cells. The 29F.1A12 antibody can reportedly block the binding of these ligands as well as other mouse PD-1-specific antibodies including clones J43, G4, and RMP1-14. Antibody-mediated inhibition of the interaction between PD-1 and its ligands can serve as an immune checkpoint blockade that can augment T-cell responses against tumor cells.
