Anti-Fli1 Unconjugated

Overview

Anti-Fli1 Unconjugated is a Mouse monoclonal targeting Fli1, supplied as a Unconjugated format for common immunoassay workflows. It supports measurement of Human target expression in common experimental systems.

Key elements and design rationale

• Clone: B2 — 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: Unconjugated — enables direct detection in fluorescence-based assays.
• 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

Fli1 belongs to the ETS transcription factor family and is expressed in megakaryocytes, macrophages, B cells and embryonic endothelial cells. It is a transcriptional activator that regulates the genes for Tie-2, GpIIb, MPL and TGF-beta RII. Human FLI1 with predicted MW of 51KDa is 452 amino acids (aa) in length. The B2 clone was raised against a full length Fli1 recombinant protein. This was shown to be able to recognize epitopes located within amino acids 30-243 of the Fli1 protein. This clone also cross-reacts with the ERG protein, another member of the ETS gene family.

Research relevance and current trends

• High-parameter immunophenotyping: combining Fli1 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

• Target detection: use the listed application(s) to compare Fli1 expression across phenotypes, treatments, or time courses.

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.
