Expression Of Recombinant Xvax2 Peptide-104 Of Xenopus Laevis And Preparation Of The Antibody

An N-terminal polypeptide (XVAX2-P104) of the XVAX2 protein, which is involved in controlling the dorsoventral patterning of the retina in Xenopus laevis, was expressed and purified as a Histagged fusion protein (pHis-XVAX2-P104), and it was employed to generate an anti-XVAX2 antibody in New Zealand white rabbits. ELISA analysis shows that the titer of the antibody is as high as ∼1:100,000. The antibody could specifically recognize the full-length XVAX2 protein in extracts of Xenopus embryos, as determined by Western Blotting.
