Product FAQs

What is the difference between the R.T.U. Animal Free Block and Diluent (SP-5035) and the 5x Animal Free Blocker® (SP-5030)?

Both products are derived from the same plant protein and in some applications can be used interchangeably. At a high level, one is presented as a ready-to-use (RTU) format and the other a more economical concentrate. The key difference is that the RTU format has been specifically optimized for use in IHC and IF applications. The RTU format has a neutral pH suitable for tissue and cell-based assays and has been more highly refined to avoid the presence of flocculent material that may cause interference with microscopy work. The 5x concentrated format is best suited for membrane blotting applications.
