What Laysan Bio does
Laysan Bio, Inc. is a privately-held life sciences company founded in 2006 and headquartered in Arab, Alabama, that manufactures and supplies activated polyethylene glycol (PEG) reagents and related bioconjugation chemistries used in pharmaceutical, drug delivery, and medical device applications. Its product portfolio spans monofunctional, bifunctional, heterobifunctional, and multi-arm PEG reagents organized across more than 20 functional-group categories — including esters (NHS, SAS, SC, SG, SS, SVA), maleimides, amines, aldehydes, biotins, carboxylic acids, epoxides, hydrazides, hydroxyls, phospholipids, thiols, silanes, and valeric acids — together with cGMP-manufactured product lines and pre-packaged conjugation kits. The company states its reagents have been qualified into multiple FDA and EU-approved drug and device products, evidencing quality system maturity relevant to regulated therapeutic and medical device supply chains.
The business operates as a specialty chemicals supplier serving pharmaceutical companies (primary segment), medical device manufacturers, and drug delivery developers. Revenue is generated through unit-priced catalog sales via a direct e-commerce storefront, with per-SKU pricing ranging from approximately $24 to $1,200 and quantity-based tier discounts. Technical documentation (MSDS, SDS, product information sheets, hydrolysis half-life data) and direct customer support ([email protected], phone) supplement the catalog motion, with custom reagent inquiries handled directly. On January 22, 2026, Laysan Bio was acquired by Gannet BioChem, a specialty CDMO backed by Ampersand Capital Partners, and the commercial offering is now delivered under the unified "Gannet BioChem & Laysan Bio" brand through the consolidated catalog.gannetbiochem.com storefront, extending the company's reach from reagent supply into an end-to-end CDMO platform serving advanced therapeutic, drug delivery, and medical device programs from early development through GMP manufacturing.

The company also offers bioconjugation expertise to support drug formulation, protein modification, drug delivery systems, and medical device functionalization.
Product overview
Laysan Bio is a life sciences company that supplies activated polyethylene glycol (PEG) reagents for use in therapeutics, devices, and diagnostics. Founded in 1992, the company has supplied PEG reagents for multiple FDA and EU-approved drug and device products. The product portfolio is organized into several categories: cGMP Products for commercial manufacturing; Monofunctional, Bifunctional, Heterobifunctional, and Multi-Arm PEG reagents; and Kits for specific conjugation applications. Products are further categorized by functional group including Esters (NHS, SAS, SC, SG, SS, SVA), Maleimides (MAL), Amines (NH2), Thiols (SH), Aldehydes, Acrylates, Epoxides, Hydrazides, Hydroxyls, Nitrophenyl Carbonates, Orthopyridyl Disulfides, Phospholipids, Protected Amines, Silanes, Biotins, Carboxylic Acids, and Valeric Acids. Featured products include MAL-PEG-SVA (heterobifunctional), mPEG2-NHS (monofunctional), mPEG-SH-4MW KIT (thiol kit), and mPEG2-MAL (monofunctional). The company operates a robust quality system supporting cGMP-manufactured products. In January 2026, Laysan Bio was acquired by Gannet BioChem, a specialty Contract Development and Manufacturing Organization backed by Ampersand Capital Partners.
