Why Researchers Choose abinScience

Pre-Conjugated & Panel-Ready Ready-to-use fluorophore conjugates — no secondary antibody needed. Optimized fluorophore-to-protein ratios for maximum signal-to-noise in multicolor panels.

Broad Fluorophore Selection From classic dyes (FITC, PE, APC) to next-generation options (BV421, BV510, BV605, AF700) — build panels with minimal spectral overlap.

CD Marker Coverage Comprehensive coverage of CD markers for immune cell phenotyping — T cells, B cells, NK cells, monocytes, dendritic cells, and stem cell populations.

Intracellular & Phospho Targets Validated antibodies for intracellular cytokines (IFN-γ, TNF-α, IL-2), transcription factors (FoxP3, T-bet, RORγt), and phospho-signaling molecules.
