Quantitative precipitin studies on the specificity of an extract from Tridacna maxima (Röding).


Haemolymph from the clam Tridacna maxima precipitated with purified H-blood-group substances, Helix pomatia galactogen, and pneumococcus type XIV polysaccharide. Although gel diffusion, gel electrophoresis, and inhibition experiments indicated that only a single precipitating lectin was present in the haemolymph, quantitative precipitin and… (More)
