Title (EN) METHOD FOR PREPARING SPECIMENS FROM CELLULAR SUSPENSION
(FR) METHODE DE PREPARATION D'ECHANTILLONS A PARTIR D'UNE SUSPENSION CELLULAIRE
Abstract:
(EN) An apparatus and method for preparing specimens of biological cells uniformly distributed over a substrate surface. The method comprises providing a suspension of biological cells in fluid, and then extracting biological target cells from the suspension to leave debris and contaminants behind. The extracted target cells are distributed over a substrate surface into a primary layer of cells coupled to the substrate surface with the remaining cells forming a secondary layer on top of the primary layer. The target cells forming the secondary layer are then removed to produce a substantially non-overlapping layer of target cells coupled to the substrate surface.
(FR) Dispositif et méthode permettant de préparer des échantillons de cellules vivantes uniformément distribuées à la surface d'un substrat. Selon la méthode, on prend des cellules en suspension dans un fluide, puis on extrait les cellules cibles de la suspension en laissant les débris et les contaminants. On distribue les cellules cibles extraites à la surface d'un substrat, de façon à former une couche primaire de cellules couplée à la surface du substrat, les cellules restantes formant une couche secondaire à la partie supérieure de la couche primaire. On élimine ensuite les cellules cibles formant la couche secondaire, de façon à produire une couche de cellules cibles sensiblement non recouvrante couplée à la surface du substrat.
