A mixture includes at least two radically curable compounds as a backbone resin, and is useful in reactive resins. In particular, the mixture reduces the viscosity of such reactive resin-containing mixtures and thus the dispensing forces required for ejecting the reactive resin components produced therefrom. The mixture also increases the performance of the reactive resins containing such mixtures and of the reactive resin components produced therefrom. Further, said reactive resins and the reactive resin components thereof are useful for construction purposes, in particular for chemical fastening.

Disclosed herein are photodegradable hydrogels and associated kits for selectively capturing and releasing cells. The hydrogels result from cross linking in the presence of a photoinitiator (1) a macromer having a polymeric backbone structure, a photo labile moiety, and a first linking moiety, and (2) a cell-binding moiety having a second linking moiety. These two components are cross-linked by a polymerization reaction of the linking moieties to form a photodegradable hydrogel incorporating the cell-binding moiety within the hydrogel. Also disclosed are methods of making the hydrogels, and methods of using the hydrogels for selectively capturing and releasing cells and for detecting cells in a fluid. Such methods can be used to detect the presence and quantity of certain rare cell types in a biological fluid.
