Figure 1. Protein-Free Blocking Buffers exhibit less background than other blocking buffers in a multiplex ELISA array. "SearchLight Arrays" were created by spotting up to 12 cytokine capture antibodies per well. The plates were then blocked with the indicated blocking buffers and the background for each well determined. Error bars represent the standard deviation for triplicate microplate wells.

Figure 2. Protein-Free Blocking Buffer efficiently blocks Western Blotting membranes.
Jurkat Apoptotic Lysate (lane 1: 0.25 µg, lane 2: 0.50 µg) was separated in 4-20% Tris-glycine gels and transferred to nitrocellulose or PVDF membranes. The membranes were blocked for 1 hour at room temperature with the indicated blocking buffer, probed with mouse anti-PARP (0.25ug/ml) followed by goat anti-mouse HRP (4ng/ml) and detected by chemiluminescence with SuperSignal West Dura Substrate.
