Yersinia ruckeri, Lyophilized qPCR

Overview

Yersinia ruckeri is a Gram-negative bacterium causing Enteric Redmouth Disease (ERM) in salmonids such as rainbow trout and occasionally Atlantic salmon. Characteristic signs include haemorrhages in the mouth, eyes (exophthalmia), darkened skin, lethargy and internal bleeding. The disease remains of commercial importance in freshwater and early grow-out phases, and is managed with vaccines in many regions.

The Yersinia ruckeri Probe-based qPCR Kit (Lyophilized) is a ready-to-use, freeze-dried reagent system for the rapid and sensitive detection of Y. ruckeri DNA in biological samples.
This assay utilizes a probe-based real-time qPCR approach to ensure high specificity and accurate quantification of bacterial load, supporting reliable diagnostics and research in fish health and aquaculture disease monitoring.

Each lyophilized reaction bead is pre-formulated with all essential components — DNA polymerase, dNTPs, optimized buffer, and fluorescent probe mix — ensuring consistent performance and eliminating the need for cold-chain logistics.

Key Features

• Specific and Sensitive: Designed for accurate detection of Y. ruckeri DNA using TaqMan-style probe chemistry.
• Lyophilized & Ready-to-Use: Each reaction bead contains all reagents; simply add nuclease-free water and DNA template.
• Room-Temperature Stable: Maintain stability for up to 12 months without refrigeration.
• Fast and Reliable: Compatible with standard real-time PCR instruments for efficient workflows.
• Convenient Format: Ideal for field testing, laboratories with limited cold storage, and routine surveillance programs.

Applications

• Detection and quantification of Y. ruckeri in fish tissue, cell culture, or environmental samples
• Aquaculture health monitoring and outbreak investigation (e.g., Enteric Redmouth Disease (ERM))
• Research use in microbiology, epidemiology, and vaccine development
