BayHisto. Send a sample inquiry
Research-use-only histology · Watertown, MA

Slides your lab can trust, on a timeline your study can keep.

BayHisto processes, sections, and stains tissue for academic and biotech research groups across the Boston–Cambridge corridor — built and run by a translational cancer biologist who has spent two decades reading slides like these for his own research.

01 — Turnaround

Same-day H&E

Frozen sectioning often returns in under an hour. Standard FFPE work ships in 24–48 hours, not weeks.

02 — Access

No waitlist

Hospital core labs prioritize clinical work first. BayHisto exists only for research samples — yours don't wait behind a biopsy queue.

03 — Expertise

IHC panels, designed

Panel design and spatial immune phenotyping from a scientist who has built these panels for his own tumor immunology research.

"BayHisto is built around one idea: a research histology lab should move at the speed of the research, not the speed of a hospital queue."
