ABSTRACT:
The present invention features stable bulking agents and blocking agents for solid phase materials containing proteins. The proteins have thiol groups which are blocked or chemically inert, preventing the formation of aggregates. Chemical solutions wherein thiol groups, if present, are blocked or chemically inert, are particularly useful in analytical applications and in diagnostic reagents utilizing solid phase materials or particles.
