Flow Cytometry Reagents

Biotium Choice Antibodies

Access antibodies developed, validated, and optimized for flow cytometry assays-available in a range of CF® Dyes, Astral Leap™ Dyes, and other high-performance fluorescent probes.

Mix-n-Stain™ Antibody Labeling Kits

Simplify and accelerate covalent antibody labeling with a wide range of CF® Dyes and fluorescent protein tags-creating custom flow cytometry reagents in as little as 15 minutes.

Apoptosis Assays

Measure apoptosis in real-time with fluorescent caspase activity, mitochondrial membrane potential, and phosphatidylserine (PS) staining assays-individually or in multi-target kits.

Dead Cell Stains

Identify dead cells with highly specific membrane-impermeant fluorescent dyes—including fixable stains and channel options for standard and spectral flow cytometry.

Proliferation & Viability Assays

Detect proliferation, apoptosis, and necrosis with bright, multiplexable dyes-stable, specific, fluorescence-based flow cytometry reagents available in a wide range of colors.

Cell Cycle Analysis

Profile cell cycle and viability using DNA-binding dyes for live, dead, or fixed cells-featuring options designed to reduce fluorescence bleed-through in flow cytometry assays.

Flow Cytometry Accessory Products

Support your workflow with ready-to-use flow cytometry products, including a formaldehyde-based fixation buffer and permeabilization buffers for consistent, convenient staining.
