Abstract

PURPOSE:To obtain the marker which can be easily prepd. by using a fragmented reaction product obtd. by chemically or enzymatically cutting a protein sample. CONSTITUTION:This invention relates to the marker consisting of the fragmented reaction product obtd. by chemically or enzymatically cutting the protein sample. The cutting reaction can be executed by using a suitable chemical or enzymatic cutting agent for the protein sample to be cut. There is no need for individually drawing and refining the respective samples which are different in mol.wt. and there is no need for adjusting the concn. as with the conventional standard sample.
