How the Ammonium-nitrate ratio affects your plants
Plants can absorb nitrogen either as nitrate (NO3-) or ammonium (NH4+), and so the total uptake of nitrogen usually consists of a combination of these two forms. It's no surprise, then, that the ratio between these two forms of nitrogen is highly significance, and affects both the plants and the medium. For optimal uptake and growth, each ...

Ammonium sulphate precipitation assay pH dependence In general does the pH effect the precipitation, e.g. would a pH of 6 cause less precipitation than pH 7.5. Or are they unrelated?
I think it would affect some proteins, but ammonium sulfate precipitation usually requires such large amounts of salt, that you would have to add a _lot When I have done ammonium sulfate precipitation, its to take a rough cut of proteins out of a whole cell/whole organ lysate - its more like a hammer than

Can one use dialysis tubing several times? I would like to know, if one can use dialysis tubes multiple times. Or is there a risk of plugging the pores? I use the tubes for dialysis of a solution that contains a preci...
This is more of a long comment than an answer, since I don't know. It could be okay, but if you are unsure whether it will work, is it really worth the risk? Here are some thoughts: * With high AS concentration, there is an initial large influx of water which can stretch the tubing. If this is repea...
