The HPLC was equipped with both an in-line radioactivity detector and a Waters 2487 dual wavelength absorbance detector (Milford, MA). == MN14-MORF Conjugation, evaluation and radiolabeling == For the preparation of MN14(SANH)-MORF, typically the MN14 antibody was incubated with a five to ten fold molar excess of NHS-SANH in 100 mM PBS (pH=8.0) for 1 h at room heat. tumored nude mice and the results compared to that obtained historically with MN14-MORF prepared by carbodiimide (EDC) coupling. == Results == Both new methods of conjugation provided between 1 and 2 gpm compared to 0.2 achieved previously by EDC. Furthermore, by repeat SE HPLC with and without CEA, both showed unimpaired immunoreactive fraction. MN14 (SANH)-MORF Epiberberine tolerated long-term storage best. More importantly, when labeled by hybridization with99mTc-labeled complementary MORF (99mTc-cMORF), the…
