The invention provides a container for storing a biomaterial in which adhesion of a minute amount of a biomarker(s) contained in the biomaterial to the surface of the container for storage can be suppressed, and sample loss is reduced, while enabling analysis with accuracy and highly precision. In particular, the container for storing a biomaterial for reducing sample loss of a biomarker(s) contained in the biomaterial has a coating containing a copolymer which contains a recurring unit which contains a group represented by the following formula (a), a recurring unit which contains a group represented by the following formula (b), and optionally a recurring unit which contains a group represented by the following formula (c), on at least a part of the surface of the container: (wherein, Ua1, Ua2, Ub1, Ub2 and Ub3, An− and Rc are as defined herein).
A container for storing a biomaterial for reducing sample loss of a biomarker(s) contained in the biomaterial, which comprises a coating containing a copolymer which contains a recurring unit which contains a group represented by the following formula (a) and a recurring unit which contains a group represented by the following formula (b):
A container for storing a peptide, which comprises
A container for fragmentation treatment of a protein and/or a peptide, which comprises a coating containing a copolymer which contains a recurring unit which contains a group represented by the following formula (a) and a recurring unit which contains a group represented by the following formula (b):
An analytical method of a fragmented protein and/or peptide which comprises
A method for measuring an absolute amount(s) of a biomarker(s) in a solution, which comprises
