Shipping gets discussed as a logistics line item, which is how it ends up owning a variable nobody is tracking. Cells do not pause while they are in transit. Whatever happens between the collection chair and your bench is already part of your experiment by the time the box arrives, and most of it is invisible on the paperwork.
Two shipping problems, not one
Fresh and cryopreserved material fail in entirely different ways, which is why treating them as one logistics question produces bad decisions.
| Fresh | Cryopreserved | |
|---|---|---|
| Target condition | Controlled ambient, typically refrigerated | Deep cryogenic, below the glass transition of the medium |
| Usable window | Short, measured in days, and cell state drifts across it | Long, provided the temperature never rises materially |
| Principal failure mode | Time. Every hour changes the cells. | A warming excursion, which may be invisible on arrival |
| Is failure detectable? | Partly, through viability and granulocyte content | Often not, until the cells are thawed and behave oddly |
| Recovery from failure | None. The collection is gone. | Another vial from the same lot, if one exists |
Dry ice and vapor shippers are not interchangeable
Dry ice holds around minus seventy-eight degrees Celsius. A charged liquid nitrogen dry vapor shipper holds far colder, near minus one hundred and fifty. That gap sounds academic and is not, because cryopreserved cells are stored below the glass transition temperature of the freezing medium for a reason. Above it, molecular mobility resumes, ice recrystallises, and damage accumulates slowly rather than dramatically.
Material held in vapor-phase liquid nitrogen and then shipped on dry ice has been warmed, even if it never thawed. Whether that matters depends on duration and on how sensitive your endpoint is, but it is a change and it should be a decision rather than an accident.

Excursions, and how you would know
A temperature excursion in transit is the failure that hides. Cells arrive frozen, look correct, thaw at a plausible viability, and then underperform in a functional assay for reasons nobody can reconstruct.
The defense is a temperature record covering the whole journey rather than a reading at each end. Ask whether the shipment carries a logger, whether the record is provided as a matter of course or on request, and what the supplier does when a record shows an excursion. A supplier who has thought about this has an answer ready. A supplier who has not will describe their packaging.
Turnaround means at least three different things
When a quote says a turnaround figure, it is worth establishing which clock is being described. Time from order to collection, which depends on donor availability and is the longest and most variable component. Time from collection to processing and release. Time from release to your loading dock. Suppliers quote whichever of the three flatters them.
The interval that actually reaches your bench
Of those three clocks, the one that changes the cells is the interval between collection and first processing. Granulocyte carryover rises with delay, and leukocytes that have been sitting in a bag have already begun responding to the fact. Everything measured downstream inherits that starting point, which is one of the less discussed reasons two suppliers ship the same nominal product and produce different results.
Most of the market treats this as a packaging problem. The structural answer is to not move the material at all before processing it. OrganaBio collects through its own apheresis subsidiary and processes within the same operation across Miami, Irvine, Hayward and San Diego, so the interval is an operational parameter rather than a function of the courier network.
What to require on arrival
Confirm the shipper type matches what was agreed. Check the temperature record before opening anything, because opening the container is itself a warming event and you want the transit record separate from your handling. Confirm vial counts against the certificate. Transfer cryopreserved material to appropriate storage immediately rather than at the end of the day, because a dry vapor shipper is a shipping container and not a freezer, and its hold time is finite from the moment it was charged.
For fresh material, note the actual time of receipt against the collection time and record it alongside your results. When a fresh lot underperforms, that interval is the first thing worth examining and it cannot be reconstructed later.
Scoping supply so logistics stop being the variable
Cryopreserved material removes most of this from the critical path, which is a large part of why it dominates multi-site and repeat-measure designs. Fresh material buys cell state that has not been through a freeze, at the cost of a schedule built around a collection date and a failure mode with no second attempt.
OrganaBio documents both across the leukopak portfolio, with cryopreserved formats held in vapor-phase liquid nitrogen, alongside cryopreserved PBMCs and isolated populations from the same donor program. The choice between formats is covered in more detail in the fresh versus cryopreserved guide.
Frequently asked questions
Can cryopreserved cells be shipped on dry ice?
They can, but dry ice holds around minus seventy-eight degrees Celsius while a charged dry vapor shipper holds near minus one hundred and fifty. Material stored below the glass transition of the freezing medium and shipped on dry ice has been warmed even if it never thawed, so it should be a deliberate decision rather than an assumption.
How would I know if a shipment had a temperature excursion?
Only from a temperature record covering the whole journey. Readings taken at each end do not capture what happened in between. Ask whether shipments carry a logger, whether the record is supplied routinely or on request, and what the supplier does when a record shows an excursion.
What does turnaround time actually mean in a quote?
It can mean time from order to collection, from collection to release, or from release to delivery. The first is usually the longest and most variable. Ask for all three dates as a sequence rather than accepting a single figure.
Why does the interval between collection and processing matter?
Granulocyte carryover rises with delay and leukocytes begin responding to storage conditions immediately. Every downstream measurement inherits that starting state, which is a common reason two suppliers ship the same nominal product and produce different results.
What should I check when a shipment of cells arrives?
Confirm the shipper type matches what was agreed, read the temperature record before opening the container since opening is itself a warming event, confirm vial counts against the certificate, and transfer cryopreserved material to proper storage immediately rather than later in the day.
How long does a dry vapor shipper hold temperature?
Its hold time is finite and begins from the moment it was charged, not from the moment it arrived. It is a shipping container rather than a freezer, so material should be moved to appropriate storage on receipt.
Does fresh or cryopreserved material carry less shipping risk?
Cryopreserved removes most logistics from the critical path and allows a second attempt from the same lot if a run fails. Fresh avoids freeze-thaw effects but ties the schedule to a collection date and offers no recovery if the shipment or the experiment fails.
