Made to the standards of our own research
At AB Biosciences, we don’t just sell reagents — we use them in our own research. Every product is produced with the highest standards of purity, consistency, and functional performance, because our own results and reputation depend on it.
That’s why our quality surpasses what other manufacturers can offer.

Mammalian Expression
Produced in HEK 293T or CHO cells for proper folding, post-translational modifications and consistent biological functionality.

Highly Purified
Low in-host proteins, size-excluded for mono-dispersion, high performance reagents

Low Endotoxin
< 1EU/mg protein endotoxin content, ready for animal studies with minimal background noises.

Biologically Active
Verification of biological activity by ligand-receptor interactions or other cognate protein-protein interactions.

Our Story
Founded in 2007, AB Biosciences began as a research lab devoted to developing protein biologics for the treatment of autoimmune diseases. Confronted with a lack of reliable, high-quality reagents for our own research, we created what we couldn’t find — an extensive panel of premium protein reagents, meticulously crafted to meet the exacting standards of our internal R&D.
Led by scientists from Biogen, Harvard University, and Harvard Medical School, our team has successfully engineered and produced more than 120 high demand proteins, each delivering exceptional purity, consistency, and performance.
In 2016, we opened our reagent portfolio to the scientific community worldwide. Today, leading institutions — including Roche, Stanford, Merck, and the NIH trust AB Biosciences to power their discoveries,

How are AB Biosciences’ reagents different from those offered by large suppliers like Thermo Fisher?
How are AB Biosciences’ reagents different from those offered by large suppliers like Thermo Fisher?
Unlike large vendors that often source reagents from third-party manufacturers, AB Biosciences designs, produces, and quality-controls all protein reagents in-house. This vertical integration ensures we have deep, first-hand knowledge of every product, allowing our team to provide direct, expert support.
Additionally, while companies like Thermo Fisher may offer the same protein reagent from multiple sources—leading to confusion during selection—we offer a single, well-characterized version you can trust for consistency and performance.
