Because the proteins in a particular organism has a lot of flat happens a lot and is not clear. Making it difficult to identify clearly that the SDS has made molecular mass proteins with different or the same.
The protein in organisms with a lot of flat happens a lot and it is not clear. Making it difficult to clearly identify the bacteria used to make SDS molecular weight proteins that are different or the same could be.
Because the protein in a creature, there are a lot of flatten caused many and was not clear. Make difficult to identified clearly was used SDS have different molecular weight protein or alike how much.
