    摘要: An electroporation device having a battery pack including a plurality of battery cells and at least one lead in electrical communication with a circuit board. The battery pack including a safety switch and a controller for selectively placing the battery cells in electrical communication with the one lead. Where the controller is in operable communication with the safety switch such that when the controller detects one or more operating conditions the controller instructs the safety switch to electrically isolate the lead from the battery cells. The battery pack also includes a manual switch, and where activation of the switch causes the controller to instruct the safety switch to electrically isolate the lead from the battery cells.

    摘要: The invention relates to a device for applying an electric field to a suspension of cells, comprising at least one chamber which comprises at least one internal space 40 for holding the suspension, the internal space 40 comprising at least two segments 41, 42, wherein each segment 41, 42 comprises at least one electrode 43, 44 and wherein neighboring electrodes 43, 44 are separated from each other by at least one gap 47 which is at least partially filled with an insulating material 46, and wherein the edges of the electrodes 43, 44 facing each other within the internal space 40 are rounded. Rounding the electrodes' edges facing a neighboring electrode results in a significant reduction of field gradients and thus even of the risk of arcing. The invention further concerns a method, wherein voltage is applied to at least one active electrode 43, 44 while the electrodes 43, 44, 45 or electrode segments next and/or opposite to the active electrode 43, 44 are set to ground potential. Setting neighboring electrodes that surround the active electrode to ground potential results in decreased scattering of the electric field within the internal space so that the electrically active area is locally limited and the field lines are focused near the active electrode and thus control of the process is enhanced.

    摘要: Methods for producing a population of human-derived glial restricted progenitor cells (GRPs) with decreased potentially unintended or undesired cellular phenotypes and/or decreased standard deviation in the cells of the population are provided. Also provided are antibody panels and gene expression profiles to characterize GRPs and a method for its use in characterizing GRP cells. In addition methods for use of these GRP cells to generate astrocytes and/or oligodendrocytes, to re-myelinate neurons and to treat glial cell related and other neurodegenerative diseases or disorders or injuries or damage to the nervous system are provided. A method to manufacture neural cells depleted of A2B5 positive cells is also provided.

    摘要: The invention relates to a method for fractionating components of a biomass of protein-rich microalgae of the
    Chlorella genus, characterised in that it comprises the following steps: providing a biomass of microalgae produced by fermentation; optionally, washing the biomass to remove the interstitial soluble compounds; thermally permeabilising the biomass at a temperature of 0ºC to 150°C, preferably 100ºC to 150°C, for a time of several seconds to 5 minutes, preferably for a time of 5 seconds to 1 minute; separating the biomass thus permeabilised from the soluble fraction using a centrifugation technique, specifically multi-stage centrifugation; optionally, recovering and clarifying the soluble fraction thus obtained by microfiltration so as to remove residual insolubles from same; separating the aforementioned soluble fraction by precipitation, in order to obtain a peptidic isolate and a peptidic concentrate.
