Application


This Cell Comb Scratch Assay has been optimized to apply a high density field of scratches to maximize the area of wound edges, while leaving sufficient undamaged cells to migrate into the gap.


Research CategoryCell Structure


EMD Millipore′s patent pending Cell Comb™ Scratch Assay addresses the need for an easy-to-use tool for creating multiple scratch wounds, The Cell Comb™ has been optimized to apply a high density field of scratches to maximize the area of wound edges, while leaving sufficient numbers of undamaged cells to migrate into the gap. This form of high density wounding creates a high proportion of migrating cells to quiescent monolayer cells, which permits sensitive detection of the biochemical events occurring, specifically in the migrating cell population.


Components


Cell Combs: Quantity of 6 individually packaged, disposable combs. Rectangular Cell Culture Plates: Quantity of 6 individually packaged, cell culture-treated 86 mm x 128 mm plates.The Cell Combs and Cell Culture Plates have been subjected to E-beam irradiation in order to minimize the possibility of contamination.

General description


Read our application note in Nature Methods!Click Here!Cell migration can be studied by a variety of methods, but the scratch assay remains a highly popular method due to the simplicity of the required materials, experimental setup, data collection and interpretation (Lian, C., et al., 2007; Cory, G., 2011). The scratch assay is typically initiated by scratching a confluent cell monolayer with a pipette tip to create a narrow wound-like gap. Shortly after wounding, the cells at the edge of the wound initiate a program to migrate into the gap, a process that continues until the gap has been completely repopulated with cells. Extent of wound closure is typically observed through light microscopy and protein expression patterns that occur during the wound healing process can be characterized by immunofluorescence.Advances in understanding the repair mechanisms of wounded cell monolayers have been facilitated by the development of methods for performing the assay in multiwell plates. Such methods include delivering wounds to existing monolayers in the wells, or occlusion of the center of the well during monolayer formation to create a gap (Yarrow, J.C., et al., 2004; Simpson K.J., et al., 2008; Gough, W., et al., 2011). Each method then involves quantification of the extent of cell migration into the gap.However, these methods are not optimal for biochemical analysis of the molecular events mediating wound repair. For example, the small scale of a basic pipette tip-derived wound provides insufficient and inadequate material for biochemical analysis
