Hi- I have a similar problem with NK cells which I isolate from
cord blood. I have been culturing them in IL-2 and IL-15 but have a high level of apoptosis in the first few days. Where you successful with your cells? I have found that there is great variability between the different cord blood units. Do you find the same with your cells?

Probably, there are no straightforward ways to detect a mycoplasma
contamination.
However, for this porpuse there is the Hoechst staining solution (Sigma, cat# H6024). Unlike other methods, there's no need to perform PCR, even though you need a flourescence microscopy.

Probably, the molecules that best fit your definition are the dideoxynucleotides (ddNTPs), the chain terminators used for the Sanger's
DNA sequencing method.

We have a problem in HeLa cell culture. In a 12 well plate, cells are dying in the outer wells (wells at the edges of the plate) while
still growing happily in the inside (central) wells. Same cells in the T75 flask are growing fine too. Wierd, isn't it? No visible bacterial contamination either.
Any thoughts?

A fluorescent light in a storage area is not an effective way of controlling
bacterial growth - the intensity of the light drops off with the square of the distance, meaning unless something is close to the bulb it'll not get sanitised.
The UV could be breaking down your media, although for the above reason's I suspect that's not the issue.
Did you do microplasma testing? Your problem ...
