Ovalbumin (OVA) is a key reference protein for vaccination experiments.
Ovalbumin, the major protein constituent of chicken egg whites, is a glycoprotein that is sufficiently large and complex to be mildly immunogenic. Consequently, it is widely used as an antigen for immunization research.
InvivoGen provides two grades of ovalbumin: EndoFit™ ovalbumin for in vivo use (vaccination, etc.) and standard ovalbumin for detection applications. InvivoGen also offers two OVA peptide standards for ELISPOT, and an OVA-expressing plasmid.
