PatoLab Polymer is a robust ONE-step polymer system that provides increased sensitivity, time savings and detection simplicity. The HRP Polymer is an innovative technology. Ultimately gives the user higher sensitivity and antibody efficiency. PatoLab HRP polymer allows the use of less antibody to obtain better signal-to-noise ratios. This system is also biotin-free, which eliminates background staining found with traditional biotin-based detection methods. For optimal interpretation of results, appropriate positive and negative controls must be included.
