the chromogenicity curves for apob-100 and for apob-48 obtained when lipoprotein samples were applied to gels in concentrations conventionally used for this technique ( i.e . 20-100 micrograms total apob/gel ) did not extrapolate to the same point on the ordinate , which precludes the use of a simple ratio or `` '' chromogenicity factor '' '' to describe their relative chromogenicities over this concentration range , hence , a novel approach was developed to determine the relative mass of apob-100/apob-48 in lipoprotein samples , based on their staining characteristics in sds-page .
