Meet Reservoir
Your immune cells shift with age and exposure. The cells you have today are biologically younger, with less accumulated damage, than the cells you’ll have tomorrow. Reservoir makes preserving them simple.
From a 15-minute appointment to long-term cryopreservation.
Draw
A trained phlebotomist comes to your home for a standard blood draw, done in about 15 minutes.
Isolate
We extract your immune cells and screen them to ensure the highest quality during the cryopreservation process.
Preserve
We resuspend your cells in a protective medium and freeze them at a controlled cooling rate.
Store
We place the frozen cells into secure, long-term cryogenic storage below −150°C in an FDA-registered facility.
Your cells are at their youngest today.
Most people wait for a reason to think about their cells: a diagnosis, a health scare, a birthday that feels different than the ones before it. But the single best day to preserve your biology is the one that feels the most ordinary: today.
Your cells, held for you, for as long as you choose.

A trained phlebotomist comes to your home for a standard blood draw of about 60 mL. No fasting needed. It takes about 15 minutes. We handle everything after that.
We isolate your immune cells, screen them for quality, and cryopreserve them at a controlled rate. They’re stored below −150°C in an FDA-registered facility, monitored 24/7.
Occasionally a sample doesn’t meet our quality threshold. It isn’t a finding about your health. We’ll cover a second draw at no cost.
You do. Nothing is released without your instruction.
No. Your cells stay in storage and aren’t used for research or anything else.
That is up to you and your physician to decide. Reservoir stores cells; we don’t diagnose or predict.
Cord blood banking collects newborn stem cells from the umbilical cord, once, at birth. Reservoir archives your adult immune cells, from a standard blood draw, at any age.
