EndoFit™ OVA protein

OVA protein for in vivo use

OVA (ovalbumin or albumin) is the most abundant protein in chicken egg whites. This glycoprotein is sufficiently large and complex to be mildly immunogenic.
 

Key features

Commercially available OVA is often contaminated with endotoxins which alter the results obtained in vivo [1]. InvivoGen ensures a high-quality OVA EndoFit™, for you to obtain accurate and reliable experimental results:

• Endotoxin levels <1 EU/mg
• Guaranteed sterile
• For in vivo use

Applications

• Model antigen for immunization experiments [2-4]
• Carrier protein for conjugation to haptens [5] and other antigens to increase their immunogenicity

InvivoGen also offers a large choice of vaccine adjuvants including alum & emulsions, PRR agonists, and conjugatable PRR ligands.
