Abstract
Disclosed are proteins which are covalently bound to a solid support at a first temperature where they have a first configuration, and then biomolecules are attached to the bound proteins at a higher temperature at which the proteins have more exposed functional groups, each such group being capable of covalently bonding to a biomolecule. The biomolecule can be, for example, a nucleic acid, including an amine functionalized oligonucleotide. The proteins can include, BSA (Bovine Serum Albumin) which can be bound using a reaction with the surface of a tosyl-activated microparticle.
Claims7
A product comprising:
- (i) a microparticle;
- (ii) a single layer of bovine serum albumin molecules covalently attached to the microparticle;
- (iii) oligonucleotides covalently attached to the single layer wherein attachment of the single layer to the microparticle is performed at a pre-selected temperature such that the bovine serum albumin molecules in said single layer attached at said pre-selected temperature display a greater number of available sites for covalent attachment of oligonucleotides than if the single layer was attached to the microparticle at a different temperature.
