Animal Sera — Normal Serum for Blocking, Cell Culture & Diagnostics
SeamlessBio supplies normal (non-immune) sera from 13 animal species. All sera are sterile filtered at 0.2 µm, EU origin, with full documentation on request. No minimum order quantity — single vials available. Batch reservation and free test volumes on request.
The correct serum depends on your secondary antibody species or experimental model. Each serum links directly to the product page for specifications, pricing, and ordering.
Blocking rule: Always use normal serum from the same species as your secondary antibody.
Example: anti-rabbit secondary → block with Rabbit Serum (NRS). Anti-goat secondary → block with Goat Serum (NGS).
Multiplex panels combining multiple secondary species → use Donkey Serum (NDS) — no cross-reactivity with mouse, rat, rabbit, goat or sheep.
