Blocking Reagents

Blocking solutions can prevent background interference from different sources, including autofluorescence, endogenous enzyme activity, Fc receptors, or interactions of detection reagents with tissue/cell proteins and other macromolecules.

Vector Laboratories offers blocking solutions for a variety of applications. To determine which blocking solution may be best for you, run series of negative controls as outlined in Vector Lab's Troubleshooting Guide (please see resource below).
