Uporaba monoklonskih protiteles CDI 315 za ciljano dostavo nanodelcev = Application of monoclonal antibodies CDI 315 for targeted delivery of nanoparticles : diplomska nalogaKužnik, AlenkaNanotehnologija se vse bolj uveljavlja na razliènih podroèjih, tudi v farmaciji, kjer nanodelci lahko predstavljajo selektiven terapevtski dostavni sistem. V diplomskem delu smo prouèevali ciljano ... dostavo nanodelcev s pomoèjo monoklonskih protiteles CDI 315, usmerjenih proti povrsinskemu antigenu na MCF-7 celicah raka dojke.Protitelesa CDI 315 smo pridobili z gojenjem ze pripravljene hibridomske celiène linije. Po izolaciji in èisèenju z afinitetnokromatografijo smo protitelesa okarakterizirali z encimsko-imunskim testom ELISA in z izoelektriènim fokusiranjem. Tarèni antigen protiteles je bil doloèen s pomoèjo 2D-elektroforeze citosolne in membranske frakcije MCF-7 celic, kateri je sledil prenos po Westernu in masna spektrometrija. Protitelesa CDI 315 smo nadaljnje adsorbirali na povrsino nanodelcev iz kopolimera mleène in glikolne kisline (PLGA), z vgrajenim fluoresceinom. Stopnjo adsorpcije smo doloèali na fluorimetru z merjenjem fluorescence sekundarnih kozjih antimisjih protiteles, konjugiranih z Alexa Fluor TM 546 fuorescenènim barvilom. Adsorpcijo protiteles smo opazovali tudi z uporabo fluorescenène mikroskopije. Na kokulturi tumorskih MCF-10A neoT celic in kontrolnih CACO-2 celic smo potrdili, da oznaèeni nanodelci selektivno vstopajo v tumorske celice.Iz dobljenih rezultatov sklepamo na moznost selektivne dostave protitumorskih uèinkovin do tumorskih celic. Nanodelci prispejo predvsem do tumorskih celic in protitumorska uèinkovina, ki je vgrajena v njih, ne poskoduje zdravih celic. Na ta naèin lahko razvijemo uèinkovitejsa in hkrati varnejsa zdravila, ki omogoèijo uspesnejsi terapevtskiizid pri zdravljenju rakavih bolnikov.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [Kužnik, A.], 2006Language - slovenianCOBISS.SI-ID - 1981041
