Abstract: A polymer substrate, such as a polymer coating or a polymer hydrogel network, includes carboxyl moieties that can be used as conjugation sites to which receptor or analyte molecules can be attached. In an example, the polymer substrate includes a polyacrylamide polymer network having alkanoic acid moieties or derivatives thereof, which can react with carboxyl activating compounds to provide an activated alkanoate moieties on the polyacrylamide network. Amine-terminated nucleic acids can react with the activated alkanoate moieties to capture the nucleic acid to the polymer network through an alkylamide moiety.

Abstract: Methods of reversal of the binding between a biotin compound and a biotin-binding compound are disclosed. A method of reversibly releasing a biotinylated moiety from a streptavidin (or avidin) coated support is shown as an example. The strong interaction between streptavidin or avidin-biotin is made much weaker by using a combination of modified streptavidin or avidin and modified biotin like desthiobiotin or a derivative thereof like DSB-X Biotin. A protein, such as an antibody may be biotinylated with the modified biotin. When this protein is isolated by binding the modified biotin to the modified streptavidin or avidin bound to an solid surface, it may be released under very gently and very rapid conditions by addition of free biotin. In contrast to proteins obtained by the prior art release methods the protein obtained using the previously available release methods, the proteins obtained using the methods disclosed herein will maintain their native conformation. Uses of the methods in various procedures including cell detachment procedures and techniques of detection, identification, determination, purification, separation and/or isolation of target proteins or nucleic acid molecules are also described.

Abstract: A silyl protected diacrylamide compound is described. A method of forming such a compound includes mixing a silylation reagent with a hydroxylated diamine compound under first reactive conditions to form a product in a first solution, separating the product from the first solution, and mixing the product with acryloyl chloride under second reactive conditions in a second solution to form a silyl protected diacrylamide compound.
