A byproduct,
refined into
a growth medium.
UBS recovers and refines bovine serum from the meat processing stream, turning material that would otherwise be discarded into a consistent, validated supplement for cultured meat and cell culture — without a fetus.
Serum, sourced
with intent.
Fetal bovine serum has powered cell culture for decades, but its supply is finite, expensive, and ethically fraught — drawn from bovine fetuses at the point of slaughter. As cultured meat moves from lab to plant scale, that supply chain becomes a bottleneck the industry can't scale through.
UBS takes a different input entirely: serum recovered from adult cattle already within the existing meat processing stream. Through a controlled collection, clarification, and quality-control pipeline, that recovered serum is refined into a growth supplement suited to cultured meat media and standard cell culture — evaluated against FBS on proliferation and viability across bovine and murine cell lines.
Built for labs that need to scale.
Everything a growth supplement needs to do — for teams who need it to keep doing it, batch after batch.
Upcycled, not extracted
Sourced from material already generated by the meat industry — no dedicated fetal harvest required.
Performance-validated
Benchmarked against FBS in proliferation and viability assays across bovine and murine cell lines.
Cost-stable supply
Priced off an existing supply stream rather than a scarce, fluctuating fetal-serum market.
Lot-level QC
Every batch is screened for microbial and mycoplasma contamination with a certificate of analysis on file.
From processing floor to culture flask.
Collection
Blood is recovered under controlled conditions at the point of processing, from cattle already within the meat supply chain.
Clarification & processing
Serum is separated, decolorized, and processed to reduce residual particulates and standardize composition batch to batch.
Quality control
Each lot is screened for microbial load and mycoplasma, and profiled for protein content before release.
Supply
Filtered, lot-traceable serum ships with a certificate of analysis, ready to supplement culture media.
Where UBS goes to work.
Proliferation media
A serum supplement for expanding bovine satellite cells and myoblasts at scale, ahead of differentiation.
Routine culture
A drop-in supplement for maintaining established cell lines without disrupting existing protocols.
Serum-free transition studies
A defined, characterized reference point for teams weaning media formulations off FBS entirely.
