One well established markermesothelin, a 40kDa cell surface glycoprotein, has been reported to be expressed by EM cells (8), but not SM (9)
One well established markermesothelin, a 40kDa cell surface glycoprotein, has been reported to be expressed by EM cells (8), but not SM (9). studied (liver, 2.62%ID/g; other organs or tissues 80% of EM and SM tissues, but not other tissues (10). In the present study, we investigated both thein vitroandin vivotumor targeting and imaging potential of an additional scFv (M40) for both EM (M28) and SM (VAMT-1) subtypes. == Materials and Methods == == Expression and Purification of M40 == The M40 was produced as previously reported (6,1113). == 99mTc Radiolabeling of M40 == The scFv was radiolabeled as previously reported (14,16). The carbonyl-kit (IsoLinkTyco/Mallinckrodt) was used to prepare the [99mTc(CO)3] moiety. An aliquot IRAK3 (4060 g) of M40 was mixed with 100500 L of [99mTc(CO)3(OH2)3]+solution and the mixture was…
