Microbiology Products

Simplify microbial research with innovative tools that deliver clarity, consistency, and speed. From selective viability dyes to sensitive Gram stains and specific primary antibodies, our microbiology products streamline workflows and enable accurate detection and analysis of live or dead bacteria, yeast, and more.

Primary Antibodies for Microbiology

Advance microbial research with highly specific antibodies against bacterial, viral, and fungal targets, available in various dye colors and labels.

Bacterial Viability

Assess bacterial viability with highly selective microbiology reagents, including dyes designed for standard flow, spectral flow, and fluorescence microscopy.

Fluorescent Gram Stains

Identify gram-positive bacteria with easy-to-use fluorescent conjugates—sensitive stains for live or fixed cells, available in bright CF® Dyes and other labels.

Other Bacterial Stains

Label bacterial cells and endospores with bright fluorescent stains in a variety of colors—offering options for all-cell labeling or live/dead discrimination.

Yeast Stains

Stain yeast cell walls, organelles, and more with bright, validated dyes—including options for viability and metabolism assessment, optimized for diverse assays.

Yeast Viability

Determine yeast viability with rapid, selective stains and kits—available in bright color combinations for broad compatibility across research workflows.

Viability PCR Reagents

Detect viable microorganisms with viability PCR reagents that deliver superior speed, sensitivity, and specificity—even for viable but not culturable (VBNC) bacteria.

PMA-Lite™ 2.0 LED Photolysis Device

Photoactivate propidium monoazide (PMA)-, PMAxx™-, or ethidium monoazide (EMA)-treated samples with a compact LED device designed for consistent, controlled activation.
