Microarray slides

Microarray slides are high quality glass chips functionalized with various chemical groups for biomolecular (protein, antibody, enzyme, polypeptide, DNA, etc.) immobilization. Two slide sizes are available: 20x20x0.4mm small size and 750x250x1mm standard size. All biochips are packaged in inert gas. All biochips are manufactured on a per order basis. Each package contains three pieces of chips. All listed prices are for per package and in USD.

Carboxylate functionalized slides carry negative charge in buffer with pH greater than 4. They can covalently bind to biomolecules with primary amine groups after EDC/NHS activiation. This binding is more efficient than aldehide-amine binging. Polyethylene glycol (PEG) is monofunctional polymer that is well known for resisting non-specific adsorption. Polysaccharides (dextran and arginic acid) have long and bulky chains. Synthetic polymers (SP) have long and slim chains. SP type I is highly negatively charged polymer due to high density of carboxylate. SP type II is mildly negatively charged polymer. SP type III has long spacer arms that extend the carboxylate groups away from the main chains.
