Why This Blocking Buffer

Engineered where standard blocking buffers fail

Particulates and inconsistent pH can raise background noise and obscure target signal in sensitive immunoassays. TBS Blocking Buffer with Gelatin (1%) is built to remove those failure modes at the source.

Microscopy & Optical Detection

Low-background blocking supports clearer immunofluorescence and chromogenic detection in microscopy-based readouts.

ConfocalBiosensorsTEER
Gelatin blocking buffer is not suitable for all membranes: it is better suited to nitrocellulose, nylon, and charge-modified nylon membranes and may not perform optimally on PVDF membranes. It is compatible with biotin, fluorescein, and DIG detection systems.
