Cation-exchange paper (P81)

Researchers at SVI have developed a cation-exchange paper replacement for GE Healthcare’s Whatman P81 and PerkinElmer's P30 filters. This product is available to the wider research community at an affordable price.

SVI phosphocellulose paper is not an exact replica of trademarked P81 paper or P30 papers – its synthesis uses a different chemistry. However, it performs as well as both P81 and P30 across a range of peptide (Arg/Lys) and protein substrates.

The paper has been used by more than 80 laboratories worldwide, since it was made available in 2018. It can be used for applications covering kinase, methyltransferase and acetylation assay applications.
