Abstract: Fusion proteins include an extracellular domain of PD1 protein (programmed cell death protein-1) and/or an extracellular domain of PD-L1 protein (programmed cell death-ligand 1 protein (CD274 or B7-H1)). Portions of the extracellular domains are expressed in specific configurations and purified as protein, which are used in immunoassays to monitor the circulating levels of biotherapeutic antibodies to these proteins. A method is for determining the amount of circulating levels of a biotherapeutic antibody in a biological sample obtained from a patient when the patient has undergone at least one dose of immunotherapy.

Abstract: The present invention relates to a method for preparing a suspension for the encapsulation of heat and moisture sensitive substances in capsules, sachets, droplets and food compositions. It also relates to methods for encapsulating, to the encapsulated products and to methods for storing the encapsulated products. The invention is extremely suitable for the encapsulation of microbial cultures. Cultures encapsulated in capsules prepared according to the method of the invention, will stay stable for a long time. At 25 degrees C. they show a stability reduction of less than 1 log per month.
