Ultra-Low Binding Microtubes: A Simple Switch for Improved Recovery in DNA and Protein Workflows

If you’re already familiar with low-retention labware, you understand that materials matter. The surfaces your samples come into contact with can influence recovery, consistency, and ultimately your results.  
 
When working with low-yield samples or sensitive assays, recovery becomes especially critical, and even small losses can impact data quality or repeatability. 

Ultra-low binding microtubes are a practical choice for applications that demand optimal sample recovery, particularly in low-concentration or molecular workflows. 

How Are Ultra-Low Binding Tubes Different ?

Low-Retention vs. Ultra-Low Binding

Low-retention tubes reduce liquid hold-up, helping ensure more of your sample is dispensed accurately. Ultra-low binding tubes go further, minimizing adsorption (when molecules stick to the tube’s surface) and protecting what’s inside the tube throughout the workflow. For applications that demand precise control, this simple switch can deliver measurable performance gains.  

What Happens Inside the Tube  

Sample loss isn’t always visible, but it adds up. Adsorption to tube walls during storage, mixing, or centrifugation can compound across a workflow, especially when starting concentrations are already low. Ultra-low binding materials help protect your sample throughout the workflow, not just during storage. 

Benefits for your sample: 

  • Minimize DNA or protein loss to tube walls and preserve low-abundance molecules
  • Maintain true sample concentration across workflow steps 

How It Improves Assay Performance 

  • More consistent input, reduced variability and improved result reliability
  • Better amplification efficiency or signal detection

Who Are Ultra-Low Binding Microtubes For? 

PROGENE® 1.5 mL Ultra-Low DNA Binding Microtubes

 
Ultra-low binding microtubes are ideal for samples that are low in concentration, high in value, or particularly sensitive to loss such as DNA, RNA, or proteins 

To support different applications, PROGENE® Ultra-Low Binding Microtubes are available in two specialized formulations, each engineered to minimize adsorption at the molecular level. 

DNA-Specific Ultra-Low Binding Formulation 

Designed to preserve every DNA molecule for accurate, high-purity results, this formulation is ideal for researchers and labs working with nucleic acid workflows, including:  

  • Low-yield or precious DNA samples, such as forensic DNA, single-cell sequencing, or rare clinical samples
  • PCR, qPCR, and DNA sequencing applications

Protein-Optimized Ultra-Low Binding Formulation 

Engineered to minimize protein adsorption and support near-complete sample recovery, this formulation helps maintain protein concentration, integrity, and reproducibility. It is designed for researchers and labs whose workflows involve proteins and peptides, including: 

  • Proteomics and mass spectrometry sample preparation
  • Antibody and enzyme handling 

Designed for the Realities of the Bench 

Beyond materials, PROGENE® Ultra-Low Binding Microtubes are built for everyday lab use: 

  • Hinged locking caps minimize evaporation and leakage
  • Withstand centrifugation up to 25,000 × g
  • Working temperature range: -80°C to 121°C
  • Manufactured in a Class 100,000 cleanroom
  • DNase/RNase-free, non-pyrogenic, human DNA-free, and PCR inhibitor-free
  • Packaged in tamper-proof, resealable bags of 50 for contamination-free storage
