StartingBlock™ Blocking Buffer (Thermo Scientific™)

StartingBlock Blocking Buffer is a single purified protein for fast blocking of western blots and ELISA assays. It provides broad compatibility with a wide range of antibodies, antibody combinations, and other protein probing and assay systems. StartingBlock Blocking Buffer is available in PBS and TBS, with and without Tween 20.

Key Features

Features of StartingBlock Blocking Buffer include:
• Strip and re-probe without re-blocking—blots stay blocked even after stripping with Restore Stripping Buffer (Cat. No. 21059)
• Compatible with many detection systems—western blot, ELISA, and IHC with antibody or avidin/biotin probes (blocker is serum- and biotin-free)
• Short blocking times—less than 15 minutes for nitrocellulose or PVDF membranes; almost instantaneous for polystyrene microplate wells
