The present invention relates to composite materials useful for purifying proteins obtained from biological feedstocks. The composite materials of the invention comprise a porous support having an average pore size of 5 to 500 nm, said porous support being filled with a first polymer which is cross-linked, and a second polymer which is not crosslinked and is covalently bonded to the external surface of the cross-linked polymer-filled porous support.

An object of the present invention is to provide a method for analyzing an isomer of triglyceride, a method for sorting oils and fats having different contents of an isomer of triglyceride, and a method for producing triglyceride of which an isomer can be fractionated. The present invention is a method for analyzing triglyceride, including a step of analyzing an isomer of triglyceride by supercritical fluid chromatography, in which multiple types of stationary phases are used in the supercritical liquid chromatography, and at least two stationary phases among the stationary phases have different chiral selectors in each of which one or more chlorines are bound to a polysaccharide derivative.

Provided herein are new compositions and methods to target and deliver agents to pathological areas by utilizing multifunctional compounds. These compounds include three or more domains: (i) a vimentin-binding peptide, (ii) a linker, and (iii) a drug binding, a capturing reagent, or a detectable moiety. These compounds can be used to detect, isolate, and/or treat cancerous cells such as circulating tumor cells.

A sample is stored in a container (125) disposed upstream of a back-pressure control valve (140). A mixed fluid of carbon dioxide in a supercritical state and a modifier is introduced into the container, and a component contained in the sample is extracted. The extracted component is introduced into a trap column (135) together with the carbon dioxide and the modifier and collected in the trap column. The trap column is loaded with polymer beads as a filler.
