Sysmex Fluorocell Reagents

Fluorocell reagents are the fluorescent staining solutions that power differential and reticulocyte analysis on Sysmex XN-Series automated hematology analyzers. Each formulation targets a specific measurement channel, so labs running high-volume complete blood counts depend on having the right reagent stocked for uninterrupted throughput. This collection carries the core Fluorocell line direct for XN-Series workflows, packaged in the standard two-container configurations your analyzer expects.

The channel each reagent serves is what matters at the bench. Fluorocell WDF (2 x 42 mL) drives the white blood cell differential, staining leukocyte populations for accurate five-part differentiation. Fluorocell WNR (2 x 82 mL) handles the WBC nucleated and basophil channel, resolving nucleated red blood cells and basophils from other cell lines. Fluorocell RET (2 x 12 mL) enables reticulocyte counting and immature reticulocyte fraction reporting, while Fluorocell PLT (2 x 12 mL) supports fluorescent platelet enumeration for reliable counts even in low-platelet samples where impedance methods struggle.

Because these are analyzer-specific consumables, compatibility is the buyer's first question: confirm your instrument is an XN-Series (or the compatible Sysmex platform noted for WDF) before ordering, and match the reagent to the channels your assay panel uses. Lot consistency and proper cold-chain handling matter for stable results, so many labs order these reagents alongside their controls and calibrators to keep QC aligned. Watch pack sizes as well — the differing container volumes reflect the sample throughput of each channel, and pairing your order to actual test volume helps minimize expired inventory.
