>We have just bought a hybridisation oven and i was wondering if you all out
>there have any tips on making the most effective use out of it..
>What has been the maximum number of filters used per bottle?
>> I have used up to 5
I often probe microtiter dish formatted filters and have used
up to 15 filters per tube for a single hybridization.
>Do you really need to use the mesh provided for placing between filters?
>> Dunno but always have.
I've never used this mesh before. Since I have been using so many
filters per tube I might consider this. What kind of mesh are we
talking about here? Is it a special product?
>What kind of hyb solution volume to surface area of filter do people use?
>> Varies for target and probe i.e DNA-DNA, DNA-RNA etc
I use 20 ml in a tube with 15 filters.
>Has anyone altered the hyb soln composition as a result of using these ovens?
No, but I use the Church procedure. However, I have had some
problems with stripped and re-probed filters. For some reason
the newly-labelled probe has an affinity for some of the microtiter
dish wells which gave me a positive signal on a previous hybridization.
>Are any brands of filter/membrane better than others in these ovens.?
>> I use Hybond N+ and alkaline transfer.
I use ZetaProbe filters.
