S sanguis interaction with cells expressing GPIb.

Binding of S sanguis to GPIb-transfected CHO cells. The panels on the right show binding of 546-labeled anti-GPIb antibody (SZ2, noninhibitory). The panels on the left show the cells by differential contrast microscopy. The top row shows mock-transfected cells, the middle row, transfected cells, and the bottom row transfected cells with an anti-GPIb antibody (AN51). These show representative images from at least 3 separate experiments. Original magnification × 1000-1300.
