Key Reasons Why You Should Consider Discovery Cryo Leukopaks

Logistics & Risk Mitigation

  • Discovery Cryo Leukopaks allow your scientists to schedule their time, experiments, and downstream processes on their preferred schedule versus a fresh delivery schedule.

Same Quality Product

  • Discovery Cryo Leukopaks have the same cell population mix, viability, and cell counts as Discovery Fresh Leukopaks.

Deep Characterization

  • Know the cell populations, HLA-Type, demographics, and real-time virus data when you select your Discovery Cryo Leukopak.

GMP-Capable Recallable Donors

  • Collect a Discovery Cryo Leukopak, screen it, and have the same donor collected under GMP conditions.

DISCOVERY'S ADVANTAGES

Scalability

Image

We have 2,800+ recallable donors that can support your research with consistent materials.

 

 

Speed

Image

We can start collections within 2 – 14 days of receiving your purchase order, and provide same-day or next-day delivery, depending on your location.

 

Consistency

Image

We maintain a single chain of custody – from collection and leukapheresis to characterization and distribution of leukopaks to our clients. This affords consistent, rigorous quality control measures throughout and improves donor recallability via well-established donor relationships.

Compliance

Image

We are FDA Licensed for Blood Products, GMP/GLP compliant, CLIA Registered and CAP registered with accreditation pending

Advanced Analysis and Cell Processing

The FDA licensed GMP Collection facility is housed in the same building as our Cell Processing, Flow Cytometry and our HudsonAlpha Discovery Sequencing and Bioinformatics, which provides highly sophisticated analyses and high quality data meeting our customers’ turnaround time needs.

READY FOR GMP COMPLIANT LEUKOPAKS FOR CLINICAL USE?

Detailed Information

Discovery Cryo Leukopaks (RUO) are manufactured from the peripheral blood of normal human donors at our wholly owned and operated US Donor Center. They are frozen quickly after collection using a controlled rate method to maximize viability.

EACH DISCOVERY CRYO LEUKOPAK (RUO) CONSISTS OF A CONCENTRATED FRACTION OF MONONUCLEAR CELLS INCLUDING:

  • B cells
  • Dendritic cells
  • T cells
  • Monocytes
  • NK cells
  • CD34+

All cells are obtained using IRB approved consent forms and protocols. Each donor is tested for HIV, HBV, HCV, and CMV, and HLA typed via 6-digit NGS. Additional characterization can be performed—please inquire.

Frequently Asked Questions

How long until I receive my first shipment of Discovery Cryo Leukopaks?
Once we receive your purchase order, we can start collections within 2 – 14 days. Depending on your location, we provide same-day or next-day delivery.
Do you have a specific thawing protocol?
Watch a demonstration on our recommended method for handling and thawing.
What cryopreservation protocol do you follow?
We use a controlled rate method that quickly freezes leukopaks after collection to maximize viability, resulting in ~95% viability post-thawing.
Where are your sites?
Our Research Use Only (“RUO”) and our Good Manufacturing Processes (“GMP”) collections are both done in Huntsville, AL, in two separate suites in the same building. Our Cell Biology Lab is also co-located in the same facility, enabling real-time fresh processing or downstream manipulation as needed.
Your samples are all from healthy, normal donors—how do you define “normal"?

For a donor to qualify as normal, they cannot be currently diagnosed or have a history of cancer, autoimmune disease, or any major comorbidity (i.e. diabetes, high blood pressure, etc.). Contact us to learn more.

How do you facilitate the transition between RUO and GMP?

Our integrated project management approach facilitates the transition between research and clinical phases. Client-specific donor pools provide premier access and flexibility for GMP and RUO collections.

 
Has COVID-19 affected your collection, processing, and/or analytical facilities?
Our collection clinic, cell processing, NGS, and flow cytometry facilities have not been negatively impacted by COVID-19. We are located in Huntsville, Alabama, and have been considered an essential business by the state, enabling our facilities to remain open and fully operational. In addition, we have been able to continuously maintain our supply chain for lab consumables, keeping all projects running on schedule.
What anticoagulant do you use for Discovery Leukopaks™?
We use ACD-A.
What apheresis equipment do you use?
We use Spectra Optia apheresis machines.
Which collection protocol/program and consumable sets are you using?
We use the CMNC (Continuous Mononuclear Cells) Protocol. This allows us to use only one separation process which is far more efficient than the MNC Protocol.
How often can you perform apheresis on a specific donor?
There must be a 61 day delay between one leukopheresis to the next donation. In addition, we require that our donors wait 21 days after a standard venipuncture (whole blood collection) before donating a leukopheresis product.
