Abstract: A process for the preparation of a beverage, a beverage base, a beverage concentrate or a beverage additive having a reduced prolamin content from prolamin-containing raw materials, comprising the following steps: a) contacting the beverage or a precursor of the beverage with cross-linking enzymes to obtain modified prolamin; b) removing the modified prolamin at least partially.

Abstract: The invention relates to a method for identifying the presence of BBB-specific protein/fragment in endothelial cells of brain capillaries, characterized in that a) endothelial cells of brain capillaries freshly isolated from brain are conventionally pre-purified by enzymatic digestion, b) the digest obtained in step a) is treated with a lysis buffer that essentially destroys present erythrocytes and apoptotic cells and maintains at least 70% of the endothelial cells of brain capillaries in vital form, c) the product obtained in step b) is optionally purified further, d) a subtractive cDNA library is prepared from the endothelial cells of brain capillaries and a subtractive tissue, e) a cDNA subtraction is performed using one ore more differential hybridization(s), f) clones from the subtractive cDNA library are verified by differential hybridization with respect to their respective expression, g) a complete cDNA sequence is prepared for the BBB-specific clones from the subtractive cDNA library, and h) the exp
