Description

R.T.U. Animal Free Blocker and Diluent is a ready-to-use solution designed to be used as an antibody diluent and a blocking reagent to stabilize diluted antibody solutions and diminish background due to non-specific binding in immunohistochemical applications. This product contains no animal-derived proteins. The R.T.U. Animal Free Blocker and Diluent is especially convenient in multiplex IHC (multiple antigen labeling) applications where antibodies from several different species are used.

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.

Technical Information

This plant protein derived product is a universal antibody diluent and blocking reagent intended for cell and tissue based immunohistochemistry (IHC) and immunofluorescent (IF) applications. This ready-to-use solution can be used as an alternative to normal sera, BSA, casein and non-fat dry milk in methods where these or other blocking agents have been found to be ineffective.

It is supplied without any sodium azide, and as such, can be used with both peroxidase and alkaline phosphatase antibody conjugates and all secondary detection reagents including polymer systems and avidin/biotin reagents that incorporate these enzymes. 

Importantly, this is a different formulation than our concentrated (5x) animal free blocker, due to the optimized conditions and neutral pH of the solution for IHC and IF methods.
