We have previously demonstrated that 111In-labeled autologous leukocyte scintigraphy is able to detect osteomyelitis in living juvenile pigs. In animal research studies, it may well be an advantage if the animals could be scanned after euthanasia. Applying traditional scanning of living animals to euthanized animals will render anaesthesia unnecessary and be ideal for obtaining good and reliabl...
BACKGROUND Nuclear medicine imaging of neuroendocrine tumours is performed either by SPECT/CT imaging, using 111In-octreotide or by PET/CT imaging using 68Ga-radiolabelled somatostatin analogs. These imaging techniques will give different image quality and different detection thresholds for tumours, depending on size and activity uptake. The aim was to evaluate the image quality for 111In-SPECT...
in this study, the preparation of 111in-bleomycin complex was optimized for temperature, time, concentration and ph during several experiments. the results showed that by the addition of bleomycin to 111in-incl3 sample (dried under flow of n2) and heating the mixture up to 90-100°c the radiopharmaceutical can be obtained in 99.5% yield and a specific activity of 1.745 ci/mmol. the final sample ...
INTRODUCTION With the introduction of positron-emitting radionuclides with half-lifes in days, such as 89Zr and 124I, radioimmunoscintigraphy (RIS) with positron-emitter-labeled monoclonal antibodies (moAbs) becomes feasible. RIS, using positron emission tomography (immuno-PET), combines the specific localization of an antibody with the high resolution of a PET camera. In the present study, sci...
Tetraspanin 8 (TSPAN8) overexpression is correlated with poor prognosis in human colorectal cancer (CRC). A murine mAb Ts29.2 specific for human TSPAN8 provided significant efficiency for immunotherapy in CRC pre-clinical models. We therefore evaluate the feasability of targeting TSPAN8 in CRC with radiolabeled Ts29.2. Staining of tissue micro-arrays with Ts29.2 revealed that TSPAN8 espression ...
A new method has been developed for conjugating diethylenetriaminepentaacetic acid (DTPA) to proteins using the N-hydroxysuccinimide active ester of DTPA. The DTPA-active ester was prepared using diisopropylcarbodiimide in a simple single step synthesis. DTPA-conjugated proteins were prepared by adding the DTPA-active ester reaction mixture to protein solutions (5 mg/ml) buffered at pH 7.0 and ...
111In-octreotide scintigraphy in patients with persistent medullary thyroid carcinoma (MTC) visualized tumors in about half of the surgically explored sites. Tumor visualization correlated with rapid tumor growth and large tumor volume as judged from calcitonin levels. The 111In concentration ratio between tumor (T) and blood (B) in surgically excised lymph node metastases of MTC showed a large...
We have studied the kinetics, biodistribution, and fate of autologous platelets labeled with 111In-oxine in rabbits. The initial recovery was 75% and mean survival time was 2.8 days when the data were analyzed by the multiple-hit gamma function model. Using a modified geometric mean for correction of attenuation, there was good correlation between the values obtained by in vivo quantification a...
