As government labs and public health agencies push forward with cutting-edge research, it’s important more than ever to have access to the right antibody tools for the job. That’s where Government Scientific Source (GovSci) comes in.

We proudly offer one of the most comprehensive selections of antibodies and antibody-related products: Whether you’re targeting a biomarker, running high-throughput screens, or engineering a therapeutic molecule, GovSci connects you with trusted suppliers and specialized solutions through multiple procurement options, and our team can provide technical sourcing assistance to ensure the products you choose align precisely with your project goals.

Monoclonal Antibodies (mAbs)

The gold standard in research and therapeutics
Monoclonal antibodies are widely used across federal labs and clinical applications. Their high specificity and broad availability make them ideal for ELISAs, flow cytometry, and targeted therapies. Through GovSci, researchers can access validated mAbs for hundreds of applications backed by responsive service and compliance-ready procurement.

Fab Fragments (Fabs)

Smaller size. Greater flexibility.
When reduced size and faster tissue penetration are critical, Fabs offer a powerful alternative. These antigen-binding fragments are perfect for imaging, blocking studies, and structural biology. GovSci works with leading manufacturers to provide Fabs tailored to your research objectives delivered through contracts like GSA, ECAT, and DAPA.

Domain Antibodies (dAbs)

Compact tools for complex targets
Looking for precision at the nanoscale? dAbs (domain antibodies) are the smallest functional antibody units, capable of reaching hidden epitopes and enabling modular therapeutic design. Popular in CAR-T and fusion protein development, dAbs are available to government labs through GovSci’s streamlined procurement channels.

Bispecific Antibodies (bsAbs)

Two targets. One solution.
Bispecific antibodies are revolutionizing areas like cancer immunotherapy by enabling dual binding to two different antigens. These sophisticated reagents can redirect immune cells, block multiple pathways, or enhance diagnostics. GovSci helps you navigate the growing bsAb landscape with sourcing support, technical insight, and fast, compliant fulfillment.
