Chicken antibodies as a tool of cytochrome P450 immunodetection

Cytochrome P450 is an important enzyme which catalyzes a large amount of reactions of endogenous and exogenous metabolism. There are compounds which increase expression of this enzyme and it leads up to the carcinogen activation and cancer formation. It includes much propagated chemopreventive compounds which are consumed abundantly in dietary supplements. It is therefore important to have the methods for determination of cytochrome P450 induction. One of these methods is the cytochrome P450 immunodetection by Western blotting. The detection of proteins on the membrane is done by the specific antibodies mostly gained from mammals. In this bachelor thesis there is the evidence that the antibodies from hen egg serve as well as the mammalian antibodies. The cytochromes P450 1A1 and 1A2 was detected by these egg antibodies after rat exposure to the model chemopreventive compounds β-naphthoflavone
