Sample preparation kits for microbiology

Kit 01 · Isolation

Universal microbial isolation from blood samples

The Camtech Microbial Isolation Kit uses a magnetic bead-based approach to isolate microbial cells directly from blood, supporting sample volumes from 0.5 mL to 10 mL. The workflow has demonstrated isolation across a broad range of organisms, including Gram-negative bacteria, Gram-positive bacteria and yeast, with performance demonstrated across 35 species and 125 strains, including clinical isolates.

Key features

• Automatable magnetic bead-based workflow
• Supports 0.5–10 mL sample volumes
• Demonstrated consistent isolation at 1–9 CFU/mL blood
  [Nature Scientific Reports Article]
• Broad organism coverage
• Tested across 35 species / 125 strains (including clinical isolates)

Kit 02 · Extraction

Simplified DNA extraction for molecular testing

The Microbial DNA Extraction Kit combines chemical and enzymatic microbial lysis in a streamlined workflow designed to produce high-quality DNA suitable for downstream molecular testing, including PCR and NGS. The protocol is fast and simple to perform.

Key features

• Chemical-enzymatic microbial lysis
• Designed to be non-inhibitory to downstream molecular testing
• Suitable for PCR and NGS
• Fewer reagents and processing steps
• Shorter protocol, easier to automate
• High yield HMW, NGS-quality DNA

Designed for: efficient microbial DNA preparation where speed, simplified processing and compatibility with downstream molecular workflows are priorities.

Kit 03 · Microbial DNA Enrichment

Enrich microbial sequences for NGS

The Host DNA Depletion Kit efficiently removes human nuclear and mitochondrial DNA, leaving only high quality microbial DNA for library preparation and sequencing. The protocol has demonstrated effective host DNA removal across a range of specimen types including blood, blood culture, urine, and saliva.

Key features

• Designed for efficient host DNA depletion
• Removes human nuclear and mitochondrial DNA
• Enables downstream NGS workflows
• Demonstrated performance with positive blood-culture samples
• Magnetic bead-based workflow under development for simplified, automatable processing
• PCR master mix available for QC of human nuclear and mitochondrial DNA depletion

Designed for: microbial whole genome sequencing from biological samples to enable species ID and AMR.

Kit 04 · Detection & quantification

Sensitive detection with quantitative growth monitoring

The PCR-based Microbial Detection & Quantification Kit uses a FaB (Fungal and Bacterial) multiplex PCR master mix for sensitive detection and delineation into Gram-negative, Gram-positive and/or Candida species. The kit also provides microbial quantification, by converting PCR Ct values into estimated microbial concentration (CFU/mL).

Key features

• Fungal and Bacterial (FaB) multiplex PCR master mix
• Detection of Gram-negative, Gram-positive and Candida targets to determine Gram status
• Sensitivity down to single-digit genomic copies per PCR reaction
• Suitable for microbial quantification via algorithm that converts gram-specific Ct values to estimated CFU/mL values [Nature Scientific Reports Article]
• Quantitative growth monitoring to support earlier downstream diagnostic testing

Designed for: rapid molecular detection and quantitative monitoring of microbial growth as part of pathogen identification and diagnostic workflows.
