    Abstract: The present invention relates to a method for coating a solid support which is suitable for being used in cell culture applications. The method comprises a step in which a solution of a carrier protein, which comprises attached thereto or as a part of its amino acid sequence at least one cell function- modulating peptide sequence, is heated to at least 50° C. and incubated same under conditions which result in the formation of soluble carrier protein aggregates comprising between 2 and 1000 protein molecules. Subsequently, the protein aggregates are brought into contact with the solid support under conditions that allow for the non-covalent adsorption of the aggregates to the support. The invention also relates to a coated solid support having non-covalently adsorbed on its surface at least one of the above-mentioned aggregate of carrier proteins aggregates.

    Abstract: For the simplified, intuitive and reliable operation of laboratory apparatuses, it is proposed that the laboratory apparatus be equipped with a control device comprising a touch-sensitive display unit (100), wherein the display unit (100) is configured to display a plurality of control elements (111, 112, 113 etc), which are assigned to different control functions of the laboratory apparatus, wherein the control elements are embodied (111, 112, 113 etc) to set parameters (121, 122, 123) of the control functions. At the same time, at least two of the control elements (111,112, 113, 114) are assigned to the same control function and embodied differently for setting the same parameter (121) of this control function. Therefore, the user is always offered a plurality of ways for setting a parameter or for operating the apparatus, such as, for example, for setting the rotational speed of a centrifuge. The touch-sensitive display unit is preferably embodied as a multi-touch screen, which is also able to recognise finger movements of the user, so-called gestures, as operator commands.
