Concentrated stock in.
A validated working dilution out.
PathABS sources concentrated immunohistochemistry antibodies from manufacturer partners, then contracts histology laboratories to titrate, stain, and certify a working protocol — delivered in the small volumes your bench actually needs.
From vendor stock to bench-ready reagent
A four-stage workflow, run against your control tissue, before anything ships.
Procure
We identify and purchase concentrated clone stock from established manufacturer partners on your behalf.
Aliquot & QC
Stock is repackaged into 1–4 mL working volumes with labeling, lot tracking, and QA/QC documentation.
Titrate
A contracted histology lab runs a dilution series against known-positive and negative control tissue.
Certify & ship
You receive the reagent, a certificate of analysis, and a written staining protocol ready for your bench.

Your satisfaction is the acceptance criterion.
If the stain isn't right, we make it right
Every dilution is run against control tissue before it ships, but we know optimization sometimes needs a second pass on your own specimens.
If you're not satisfied with the result, we'll re-titrate at no charge or accept the reagent back — no extended negotiation required.
- Certificate of analysis with every shipment
- Lot-tracked labeling and QA/QC records
- Re-optimization or return if staining underperforms
- Optional in-lab training on the finished protocol
