- Abstract:
The binding of antibodies onto the lamellar system of Antirrhinum majus
was determined in dependence on the serum addition. The unspecific
adsorption of serum proteins was taken into account or eliminated. The
binding of antibodies as a function of the amount of serum added is seem
from a saturation curve. From an antiserum obtained by hyperimmunization
with stroma-freed chloroplasts, the chloroplasts bind maximally 1 gram
antibodies per gram stroma-freed chloroplasts. From an antiserum to the
proteins of the thylakoid membrane prepared in the same way an equal
amount of antibodies is adsorbed. It is assumed that with this amount the
surfaces of the lamellar system accessible to antibodies is completely
covered by antibodies. For an antiserum to monogalactosyl diglyceride a
maximal antibody binding of 0.16 g, for sulphoquinovosyl diglyceride 0.12
g and for phosphatidyl glycerol 0.13 of antibodies per gram stroma-freed
chloroplasts are obtained. The significance of these results with respect
to the molecular surface structure of the thylakoid membrane is discussed.
