Fresh Frozen / OCT Tissue Block

US Biolab maintains an evolving banked collection of fresh frozen, and OCT-embedded samples from healthy and diseased donors. Custom sample sets are sourced from our global partners. Please speak to us about your research needs.  Contact our Specialist

Cellular Viability

Preserved cell structure and morphology

Molecular Integrity

Intact RNA, DNA, and protein profiles

Custom Sample Sets

Tailored to your research specifications

Controlled Storage Conditions

Maintained at optimal cryogenic temperatures

Our team will work with yours to develop sample sets that meet your specific needs.

When cellular viability is essential, fresh samples are preferred as freezing significantly reduces viability. However, when molecular integrity is the priority, fresh-frozen samples will deliver greater flexibility and will avoid protein denaturization.

Access a Worldwide
Network of  Viable Sources

Precision is essential to the success of your development project. Our integrated global network ensures you can access the specific samples needed to advance to the clinic and beyond.

Frozen samples may be accessed from banked inventories. Fresh tissue collections are guided by carefully designed prospective collection protocols. Such samples can be shipped directly to the researcher within tight timeframes, depending on the geographical location.

As with any tissue samples collected prospectively, donor matched biofluids or normal adjacent samples may be provided on request.

Custom Collections on Request

All samples in our biobank are sourced from our global network of hospitals, laboratories, and research facilities,
each IRB-compliant and approved for research.

We welcome inquiries into custom collections and invite you to connect with us to discuss your project. Matched 
samples are available in most formats, and our board-certified pathologists will work closely with you to ensure
you have the tissue samples you need to support your research.

Frequently
Asked Questions

Common questions about our fresh frozen and OCT tissue specimens

What temperature are specimens stored at?

All fresh frozen specimens are maintained at -80°C or below in monitored, alarmed freezers with backup power systems. OCT blocks are stored at -20°C to -80°C depending on anticipated usage timeline. We maintain comprehensive temperature logs and provide chain-of-custody documentation with every shipment.

How quickly is tissue frozen after collection?

All fresh frozen specimens are maintained at -80°C or below in monitored, alarmed freezers with backup power systems. OCT blocks are stored at -20°C to -80°C depending on anticipated usage timeline. We maintain comprehensive temperature logs and provide chain-of-custody documentation with every shipment.

Can I get both frozen tissue and FFPE from the same case?

All fresh frozen specimens are maintained at -80°C or below in monitored, alarmed freezers with backup power systems. OCT blocks are stored at -20°C to -80°C depending on anticipated usage timeline. We maintain comprehensive temperature logs and provide chain-of-custody documentation with every shipment.

What sizes and quantities are available?

All fresh frozen specimens are maintained at -80°C or below in monitored, alarmed freezers with backup power systems. OCT blocks are stored at -20°C to -80°C depending on anticipated usage timeline. We maintain comprehensive temperature logs and provide chain-of-custody documentation with every shipment.

What clinical data is provided with specimens?

All fresh frozen specimens are maintained at -80°C or below in monitored, alarmed freezers with backup power systems. OCT blocks are stored at -20°C to -80°C depending on anticipated usage timeline. We maintain comprehensive temperature logs and provide chain-of-custody documentation with every shipment.
