XENOPROBE is our name for our line of streptavidin coated products.  Our products are different from most of the other streptavidin products currently available because the streptavidin is covalently attached to the surface.The covalent attachment is achieved by a proprietary attachment chemistry which binds the streptavidin without affecting its biotin binding properties.

 

Covalent attachment provides exceptional uniformity and stability.  AFM studies have shown that the streptavidin is primarily present as a monolayer, with few uncoated spots and few multilayer attachment points.  There are approximately 10 exp(13) biotin binding sites per square centimeter, although steric hinderence limits the number of biotin labeled molecules that can be attached.

 

 

The XENOROBE products are available in standard 96 well plate format and as strip plates, which have 12 strips of 8 wells in a frame in the standard  8 x 12 format.  While more expensive than solid plates, the advantage of this format is that you can use as few or as many wells as needed in any given assay without the possibility of contamination of the other wells by spillage.
