Banding patterns

Banding pattern

(Science: genetics) chromosomes stained with certain dyes, commonly quinacrine (Q banding) or giemsa (g banding), show a pattern of transverse bands of light and heavy staining that is characteristic for the individual chromosome.

The basis of the differential staining, which is the same in most tissues, is not understood: each band represents 5-10% of the length, about 10exp7 base pairs, although this is not true for polytene chromosomes in drosophila that show more than 4000 bands.

Re: protein purification Ni-NTA

... also try different IMAC resins to see if there are differences in the banding patterns, again suggesting that they could be non-specifically bound contaminants.
