Immunoblot analysis of Kidd/urea transporter protein from erythrocyte membranes of individuals with common and rare Jk phenotypes.
The RBC membrane proteins (40 μg) were separated by SDS-PAGE and immunoblotted with an affinity-purified rabbit antibody against theN-terminus of the Kidd/urea transporter protein, as described in Materials and methods. Size of products (kd) on the left.
