Overview
PD1 APC-iFluor700 is a Mouse monoclonal targeting PD1, supplied as a APC-iFluor™ 700 format for FC workflows. It supports measurement of Human target expression in common experimental systems.
Key elements and design rationale
- Clone: 8G10 — consistent clone identity can support panel reproducibility and cross-study comparisons.
- Isotype: IgG1, k — informs selection of matched controls and secondary reagents when relevant.
- Conjugate: APC-iFluor™ 700 — enables direct detection in fluorescence-based assays. Excitation is typically matched to Red (633nm) lasers in cytometer configurations.
- Host species: Mouse — useful for panel design and control strategy planning.
- Reactivity: Human — interpret staining in the context of species-specific sequence and expression differences.
Key specifications such as clone identity, isotype, and fluorophore conjugation help researchers align panel design, control selection, and instrument configuration with the biological question and sample type.
Biological background
The clone 8G10, a mouse monoclonal antibody selectively binds with a 50-55 kD cell surface protein commonly known as Programmed cell death 1 (PD-1) or CD279, a member of the immunoglobulin superfamily. PD-1 expression is mostly observed in activated T cells and B cells, and also in dendritic cells. PD-1 signals via binding its two ligands, PD-L1 and PD-L2. Upon ligand binding, PD-1 signaling inhibits T-cell activation, leading to reduced proliferation, cytokine production, and T cell death. Blocking of PD-1 by its antibody restores T cells immunity against tumor and infectious agents. PD-1-blockade based immunotherapy is, therefore, highly clinically useful against various types of cancers and infectious diseases.
Research relevance and current trends
- High-parameter immunophenotyping: combining PD1 with complementary lineage and activation markers to resolve complex cell states.
- Panel standardization and data comparability: increasing emphasis on consistent reagents, compensation-aware fluorophore choices, and shared gating strategies.
- Integration with single-cell multi-omics: pairing surface marker profiling with transcriptomic or proteomic readouts to connect phenotype to function.
Common research applications
- Flow cytometry: quantify PD1-positive populations and compare expression distributions across conditions or time points.
- Cell sorting: enrich PD1-defined subsets for downstream RNA/protein assays or functional readouts.
Changes in measured signal are typically interpreted in the context of cell subset frequency, activation/differentiation state, and sample processing effects rather than as a standalone readout.
Notes for experimental interpretation
- Fluorophore selection: consider brightness, spectral overlap, and instrument configuration; compensation and spillover can affect apparent population boundaries.
- Biology-driven confounders: activation state, differentiation, and isoform/PTM variation can shift epitope accessibility and apparent expression.
- Control concepts: include matched isotype and fluorescence-minus-one (FMO) controls where appropriate, and interpret results alongside biological positive/negative reference samples.
For antibody-based assays, monoclonal versus polyclonal format can influence epitope recognition breadth and signal consistency. Conjugated antibodies support direct detection and can simplify multicolor panel design when paired with appropriate controls and instrument settings.
