In Vivo Antibodies | Low-Endotoxin for Animal Studies

Home > Products > Antibodies > Invivo Antibodies

Browse 500+ in vivo-grade antibodies formulated for preclinical animal studies. Low-endotoxin, azide-free formulations suitable for immune cell depletion, checkpoint blocking, cytokine neutralization, and receptor modulation studies. For the highest purity requirements, see our InVivo Plus line with ultra-low endotoxin (≤0.001 EU/µg). All products are designated Research Use Only (RUO) — not intended for diagnostic or therapeutic procedures. RUO

Why Researchers Choose abinScience

Depletion & Blocking Validated Antibodies validated for in vivo immune cell depletion (CD4, CD8, NK) and pathway blocking (PD-1/PD-L1, CTLA-4, TNF-α) in mouse models.

Low Endotoxin & Azide-Free Formulated without sodium azide and with controlled endotoxin levels — reducing off-target inflammatory effects in animal studies.

Scalable Quantities Available in bulk sizes (mg scale) for dosing studies. Consistent lot sizes for multi-week treatment protocols in preclinical efficacy and toxicology studies.
