I have seen that before, in fact I posted a question about in on my website. My best answer so far, is that day I incubated the cells in CO2 for one of the steps. When I repeated the assay in regular air/water bath, I did not see the cells. When I tried it in CO2 again, there they were, again. That's more of an observation than an answer but I would be curious to see what every one else has to say? Maciej __________________________________________________ Do You Yahoo!?
