Ovalbumin for in vivo use

Ovalbumin (also known as albumin or OVA) is a key reference protein for immunization. Ovalbumin is the most abundant protein in chicken egg whites.

Ovalbumin is a glycoprotein that is sufficiently large and complex to be mildly immunogenic.

Consequently, ovalbumin is widely used as an antigen for immunization experiments [1-3]. Furthermore, ovalbumin can be used as a carrier protein for conjugation to haptens [4] and other antigens to make them more immunogenic.

For accurate and reliable experimental results, the quality of ovalbumin is crucial.

However, commercially available ovalbumin is often contaminated with endotoxins which alter the results obtained in vivo [5].

InvivoGen provides EndoFit™ ovalbumin which has endotoxin levels <1 EU/mg, furthermore, EndoFit™ ovalbumin is guaranteed sterile.

EndoFit™ Ovalbumin is a high quality ovalbumin protein with an endotoxin level in vivo use.
