| abstract |
This invention relates to a method of binding antigenically active materials to the surface of water insoluble, hydrophobic polymeric substances which comprises pretreating the waterinsoluble hydrophobic polymeric substance with an aldehyde of the formula, OHC-X-CHO, wherein X may be -(CH 2 )-n, wherein n is an integer of from 1 to 10; cycloalkyl, for example, cyclopentyl, cyclohexyl; monocyclic aryl, for example, phenyl, and thereafter contacting the thus treated polymeric material with the purified antigenically active material to be bound thereto. The final products of this invention are employable as diagnostic products. |
