>Identification of spot proteins by mass spectrometry is now ongoing in our laboratory. But we have not yet succeeded in assigning any spot on the 2-D gel map to proteins which have been reported as a cell senescence marker. We may achieve direct identification of spot proteins if the specific antibody is available. But unfortunately we don't have such antibody. So I would like to ask for collaboration with researchers who may offer specific antibodies against cellular senescence-related proteins to assign the location on our 2-D gel map.
>We have a plan to compare our 2-D gel map with keratinocyte database prepared by Celis in Danish Centre of Human Genome Research. Common denominators will be applied to matched proteins between two databases.
