this study correlates tests of gelsolin 's severing function with quasielastic light scattering measurements of the size of mixed lipid particles and shows that the previously demonstrated diminution of the maximal effect of pip2 in micellar form by aggregation of the micelles or mixing with other phospholipids is not the result of an absolute requirement for small lipid particles , but rather the masking of critical sites by aggregation , by sequestration in multilamellar vesicles , or by dilution of the polyphosphoinositides below a critical concentration .
