Stabilization of lyophilization-sensitive antibody-enzyme conjugates

A simple method for stabilization of lyophilization or freezing/thawing sensitive enzyme-antibody conjugates is described. The method involves soaking of these reagents directly onto the placebo homoepathic sugar tablets followed by a brief air drying. This solid dry formulation is stable at elevated room temperature and is very convenient for storing or shipping small aliquots of these lyophilzation sensitive reagents.
