Blocking Reagents

Vector Laboratories offers a robust portfolio of blocking reagents designed to optimize immunostaining workflows by minimizing nonspecific binding and background interference. These reagents are essential for improving signal clarity across a variety of applications including immunohistochemistry (IHC), immunofluorescence (IF), immunocytochemistry (ICC), blotting, and ELISA. The lineup includes Protein Blocking Reagents such as normal sera, Carbo-Free Blocking Solution, high-purity Bovine Serum Albumin (BSA), and Animal-Free Blocking for multiplex assays. To address endogenous enzyme activity, Endogenous Enzyme Blocking Reagents like the dual-action BLOXALL® and Levamisole are provided. Endogenous Biotin Blocking Reagents and Autofluorescence Quenchers such as the TrueVIEW® Quenching Kit further enhance specificity in detection systems. For sensitive species-matched applications, Species-on-Species Blocking Kits ensure accurate results in complex tissues. Together, these solutions empower researchers with versatile, high-performance tools that support consistent, reliable staining and data integrity in even the most demanding experiments.
