این پایان نامه در ابتدا به چگونگی اندازه گیری ضرایب نفوذ منفرد با استفاده از تکنیک pfg اسپکتروسکوپی nmr و تحلیل طیفها بوسیله برنامه core می پردازد و سپس با بدست آوردن ضرایب نفوذ منفرد اجزا سیستم به مطالعه سیستم سورفکتانهای triton x-100, ctab و sds می پردازد که نقاط cmc سورفکتانتهای ctab و triton x-100 بدست آمد و سپس مخلوط این دو سورفکتانت بررسی شد و وجود سینرجیسم...
Experiments were performed to determine whether platelets contain a membrane skeleton. Platelets were labeled by a sodium periodate/sodium [3H]borohydride method and lysed with Triton X-100. Much of the filamentous actin could be sedimented at low g forces (15,600 g, 4 min), but some of the actin filaments required high-speed centrifugation for their sedimentation (100,000 g, 3 h). The latter f...
GPI-linked membrane folate receptors (MFRs) have been implicated in the receptor-mediated uptake of reduced folate cofactors and folate-based chemotherapeutic drugs. We have studied the biosynthetic transport to and internalization of MFR isoform alpha in KB-cells. MFR-alpha was synthesized as a 32-kD protein and converted in a maturely glycosylated 36-38-kD protein 1 h after synthesis. 32-kD M...
Cryo-TEM was carried out on samples containing polyelectrolyte-micelle complexes, formed by combining poly(diallyldimethylammonium chloride) (PDADMAC), a strong cationic polyelectrolye, with oppositely charged mixed micelles of sodium dodecyl sulfate (SDS) and nonionic Triton X-100 (TX100), in 0.40 M NaCl. Complexation appears to involve the formation of micelle-rich regions, presumably within ...
Article history: Received on: 02/03/2013 Revised on: 29/03/2013 Accepted on: 15/04/2013 Available online: 12/05/2013 This study is an investigation of the physicochemical interaction of Losartan potassium (LST K), an angiotensinII receptor (type AT1) antagonist, with micelles of triton X, a nonionic surfactant. The effect of micelles on the spectral properties of LSTK was monitored on at pH 7.4...
