Title: A plate for media exchange to promote tissue growth and a method for high throughput screening of tissue
Inventor: EVERETT KEITH
IPC: B01L3/00
Filed: 2002-05-29
Abstract: A multiple well plate and method for media exchange, including a body defining a plurality of cell wells each connected via a channel to one of a plurality of aspiration holes, is provided. The cell wells contain a porous, hydrophilic frit which is suspended on a ledge above a reservoir of fluid media and supports a tissue sample. The properties of the frit wick the fluid media upwards to supply the tissue sample with nutrients for growth and proliferation. Old media is aspirated from the wells by a liquid handling device which inserts a pipette tip into the aspiration holes. The pipette tip applies a suction pressure which draws the media out of the cell well, through the channel, into the aspiration hole and out through the pipette tip. New media is dispersed through the pipette tip and directly into the cell well.

Title: Nouvelle technologie de cartographie genetique
Inventor: MA PINGSHENG
IPC: C12Q1/6876
Filed: 2002-06-21
Abstract: Procédé servant à dresser la cartographie génétique d'organismes eucaryotes et consistant à introduire des oligonucléotides multiples d'ADN artificiel dans des positions neutres dans le génome d'une souche unique de l'organisme afin de créer une souche marquée artificiellement. Cette souche contient un nombre important de marqueurs spécifiques composés soit des oligonucléotides introduits seulement, soit de ces oligonucléotides et d'une partie de la séquence d'ADN adjacente. La souche marquée artificiellement est croisée avec une autre souche présentant un ou plusieurs traits distincts. On regroupe l'ADN des ségrégants du croisement présentant un trait spécifique et on détecte la présence des marqueurs artificiels dans l'ADN regroupé. La position cartographique génétique de la totalité des gènes jouant un rôle dans l'élaboration de ce trait est indiquée par une chute de l'intensité du signal des marqueurs artificiels les plus proches de ces gènes. Ce procédé permet d'utiliser des souches isogéniques pour établir la cartographie génétique. Il permet également d'accumuler des nombres importants de mutations dans une seule souche jusqu'à la génération d'un phénotype défini et d'établir ensuite la carte des mutations associées à ce phénotype. Dans un autre mode de réalisation, on accumule des nombres importants de mutations dans la souche marquée artificiellement jusqu'à l'obtention d'un phénotype, puis on croise cette souche à mutations multiples croisée artificiellement avec une souche sauvage, on regroupe l'ADN de la totalité des ségrégants affichant ce phénotype sauvage et on détecte la présence des marqueurs artificiels. La position cartographique génétique de tous les gènes nécessaires à la restitution de ce phénotype sauvage est indiquée par une chute de l'intensité du signal des marqueurs artificiels les plus proches de la position de ces gènes. Dans un autre mode de réalisation, on ajoute au marqueur artificiel un site de restriction d'un enzyme de restriction rare, ce qui permet de diviser l'ADN génomique en différents fragments contenant chacun un marqueur spécifique. On introduit ces fragments dans un vecteur afin d'élaborer une banque génomique dans un organisme hôte, dont on peut trier les transformants selon la position du fragment dans le génome. Après transformation de cette banque génomique en souche réceptrice, on peut repérer la totalité des fragments au moyen du marqueur spécifique par l'intermédiaire d'une de plusieurs techniques disponibles.
