Fig. 7. Western blot of salt/ethanol wash proteins showing a band reactive with
antiserum against a glycophosphatidylinositol (GPI)-anchored folate receptor
and reactive with anti-cross-reactive-determinant antiserum. Lane 1, treated
with antifolate-binding-protein antiserum. The protein band at the arrow has
an approximate molecular mass of 37 kDa. Lane 2, treated with
anti-cross-reactive-determinant antiserum. Note that a band at the same
molecular mass, 37 kDa, is recognized. Gels contained 12% polyacrylamide.
