Abstract: Magnetic particles capture a biological target molecule for cryo-electron microscope imaging. The magnetic particles include paramagnetic beads. At least two spacer modules extend from a periphery of the paramagnetic beads comprising a first spacer module and a second spacer module. The first spacer module binds the nanoparamagnetic beads and the second spacer module is located outwardly of the first spacer module and binds the first spacer module. The first spacer module includes first spacer proteins and the second spacer module includes second spacer proteins. A capture module is linked to an outer location of the second spacer module. The capture module includes capture proteins that are adapted to capture target molecules. At least two spacer modules are arranged so that a combined length of the at least two spacer modules locates the capture module a distance that is spaced from the nanoparamagnetic beads.

Abstract: An artificial catalyst system which can acylate chromosome proteins with high selectivity has successfully been established by using a combination of an acyl CoA activating catalyst having target acylation area binding ability and acyl CoA or a derivative thereof.
