Molecular wieght of proteins and associated materials can be used for qaalitative analysis using western blot etc. i need to find the properties of fecal progesterone metabolites
I don't think the steroid metabolites will add much to the weight of the antibodies. Is that what you are concerned about? The difference might be too small to detect.
i just want to find out the molecular weight of antibodies to faecal progesterone metabolite (any). was thinking of qualitative and quantitative analysis of the antibody to the metabolite.
