Welcome to the next evolution of molecular visualization. At Creative Biolabs, we have built our reputation on providing high-fidelity CRO services and specialized reagents that empower the global research community. We are proud to bridge the gap between genomic data and visual spatial context with the launch of our Microbial FISH (Fluorescence In Situ Hybridization) Probes.
As researchers increasingly shift from "what" is in a sample to "where" and "how" those organisms interact, the need for highly specific, robust, and validated detection tools has never been higher. Our new Probes category is designed to meet this demand, offering a comprehensive suite of fluorescently labeled oligonucleotides tailored for the identification, localization, and quantification of microbial taxa in diverse environmental and clinical research samples.
The Power of Visualization: Why FISH?
Microbial ecology and clinical microbiology have been revolutionized by Next-Generation Sequencing (NGS). However, sequencing often requires the destruction of the sample's physical architecture. Fluorescence In Situ Hybridization (FISH) serves as the essential counterpart to sequencing by allowing researchers to see microbes in their natural state.
By using fluorescently labeled DNA or RNA probes that bind to complementary ribosomal RNA (rRNA) sequences, FISH enables:
-
Spatial Mapping: Observe how bacteria cluster in biofilms or gut tissue.
-
Single-Cell Resolution: Identify individual cells without the need for culturing.
-
Activity Correlation: Link specific taxa to metabolic functions when combined with techniques like MAR-FISH or Bio-Orthogonal Non-Canonical Amino Acid Tagging (BONCAT).
Our Microbial FISH Probes Products
Our initial launch focuses on the most critical taxonomic groups and specialized applications requested by our partners in academia and industry. Each probe is synthesized under rigorous quality control standards and optimized for high signal-to-noise ratios.
-
Phylogenetic Backbone Probes: These are the "bread and butter" of microbial FISH. We offer universal and domain-specific probes designed to establish the total biomass or broad community structure of a sample.
-
Clinical and Pathogenic Research Probes: Tailored for researchers studying host-pathogen interactions or the human microbiome.
-
Environmental and Industrial Probes: For the study of nutrient cycling, wastewater treatment, and bioremediation.
-
Custom Probe Synthesis & Design: We understand that "standard" isn't always enough for cutting-edge research. Our CRO team offers custom design services where we:
-
Perform in silico specificity checks against the latest SILVA or Greengenes databases.
-
Optimize melting temperatures (Tm) for multiplexing.
-
Provide a variety of fluorophores (Cyanine dyes, Alexa Fluors, ATTO dyes) to fit your microscope's filter sets.

Technical Excellence: The Creative Biolabs' Difference
Microbial communities rarely exist in isolation. Whether you are studying the human gut microbiome or a deep-sea hydrothermal vent sample, the challenge lies in distinguishing a single species among thousands. Our probes target the 16S ribosomal RNA (rRNA), a proven marker for phylogenetic identification. Because cells contain thousands of ribosomes, targeting rRNA provides a built-in signal amplification, making even the smallest microbes visible under a fluorescence microscope. In the world of FISH, the difference between a clear signal and background noise lies in the chemistry. Our probes are engineered with several key advantages:
Purity
All probes undergo HPLC purification to ensure ≥85% labeling efficiency.
Stability
Formulated for long-term storage without significant fluorescence quenching.
Validation
Every batch is tested against positive and negative control strains to ensure the hybridization parameters we provide are accurate.
Permeability Optimization
We provide protocols and specialized buffers to help our probes penetrate even the toughest cell walls, such as those of Gram-positive bacteria and yeast.
Advancing Your Research Workflow
The launch of our Probe line is more than just a new product catalog-it is an invitation to collaborate. By integrating these probes with our existing CRO services, such as tissue processing, slide scanning, and image analysis, we provide a true end-to-end solution for spatial microbiology.
Whether you are exploring the complexities of the human microbiome or seeking to understand the microbial architecture of industrial bioreactors, our probes provide the precision you need to see what others miss.

Frequently Asked Questions (FAQs)
Are these probes intended for diagnostic use?
No. All Creative Biolabs' probes are labeled For Research Use Only (RUO). They are designed for laboratory research, environmental testing, and preclinical studies. They are not intended for use in human diagnostic or therapeutic procedures.
What is the recommended hybridization temperature?
While 46°C is standard for many rRNA-targeted probes, the optimal temperature and formamide concentration depend on the specific sequence. Each shipment includes a technical data sheet (TDS) with validated hybridization conditions.
Can I use these probes for multiplexing?
Absolutely. Our probes are designed to be used in combination. We recommend using fluorophores with minimal spectral overlap to visualize up to three different taxa simultaneously in a single field of view.
How do you ensure the probes don't cross-react with non-target species?
We use advanced bioinformatic tools to ensure each probe has at least 2-3 mismatches with non-target sequences in the same environment. For highly similar species, we offer unlabeled "competitor probes" to block non-specific binding sites.
Do you provide the hybridization buffers as well?
Yes, we offer a "FISH Essentials Kit" which includes optimized hybridization buffers, wash buffers, and mounting media containing DAPI for nuclear counterstaining.
