The Chicken egg ovalbumin protein (OVA,>98% pure, Low endotoxin, antigen grade) is manufactured for Research Use Only or for diagnostics purposes.
Chickens like all bird species have IgY antibodies that are very stable and found in the yolk. Gallus Gallus domestica is the Latin name of the Chicken.
Antigens are peptides or recombinant or native dependent on the production method.The ultrapure egg ovalbumin protein (OVA,>98% pure, endotoxin, antigen grade) supplied from adi is supplied in 1. The reagent contains very low traces of production synthesis impurities and is highly purified by ultra filtration and distillation for the chemical compounds.
Ovalbumin (abbreviated OVA) is the main protein found in egg white, making up 60-65% of the total protein. Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine protease inhibitor. The function of ovalbumin is unknown, although it is presumed to be a storage protein. OVA is also the best characterized and the first antigen proteins used as a transgene to make transgenic mice. Many different transgenic mouse models have systemic OVA expression driven by the ubiquitously expressed b-actin promoter or tissue-specific OVA expression with insulin promoter to drive the transgene expression, for studying type I diabetes, or in different isoforms, secreted or cell-membrane associated, and more recently as inducible transgene models. These C57BL/6 mice, BALB/c mice models are well characterized, and have contributed to our understanding of immunogenicity and tolerance by the OVA model.
